Abstract:

Eudendrium pocaruquarum , a new species of athecate hydroid referable to the family Eudendriidae, is described from the state of São Paulo, Brazil. The species is very similar to the widespread Eudendrium ramosum (Linnaeus, 1758), differing from it in the smaller size of the large microbasic euryteles. Longstanding problems in the systematics of eudendriid hydroids are noted, and the inadequacies of many early descriptions of species are discussed. The nematocysts provide a supplementary character for discrimination of species of Eudendrium, although information on the cnidome appears to have been sometimes misinterpreted in literature.

Abstract:

Four species of foraminifers Rosalina globularis, Lobatula lobatula, Acervulina inhaerens and Miniacina miniacea were observed as epibionts on some species of the athecate hydroids of the genus Eudendrium—E. armatum, E. glomeratum, E. moulouyensis and E. racemosum—from the Mediterranean Sea. The abundance and the distribution of the protozoans were determined for each hydroid and considered in relation to the shape and size of the Eudendrium branches. Results revealed differences in the composition of the epibiontic assemblage among different species of Eudendrium which were dependent on several factors, but were mainly related to the habitat and to the morphology of the host.The interactions between Eudendrium and its epibionts were considered to emphasize the role of the Eudendrium colonies as a hotspot not only of poorly known species but also of co-evolutionary relationships and life histories.

Abstract:

Previous evidence has shown that benthic hydroids capture all kinds of available prey and the only known constraint was prey size. Among the prey captured are phytoplankton cells but it is not known whether they are digested and assimilated. To test the hypothesis that benthic hydroids assimilate phytoplankton cells, a series of feeding experiments was carried out with the Mediterranean species Eudendrium racemosum. Ingestion rates and assimilation efficiency were determined by analysing the 14C incorporated from a labelled population of the diatom species Thalassiosira weissflogii. Eudendrium racemosum fed on T. weissflogii, after a period of starvation, and with the diatoms as the sole food item. In the presence of approximately 15,000 diatoms ml−1, Eudendrium fed at rates ranging from 16 to 55 diatoms polyp−1 hour−1. Accumulation of radioactivity in the hydrocaulus and the polyps of the hydroids were observed. A maximum ingestion of 31.6 diatoms per μgC of polyp (i.e. 175 diatoms per polyp) was observed in the experiments. Most of the diatom 14C ingested would have ended up in the Eudendrium tissue (efficiency 94%), and it was expected that a certain percentage would have been respired by the polyps. These data show that Eudendrium feed on phytoplankton, which can satisfy almost 100% of their energy demand when this type of food is sufficiently abundant.

Abstract:

A new species of the cosmopolitan genus Eudendrium, E. klausi, is described from Carrie Bow Cay, Belize. The species is characterized by a small colony with an intense blue colour, polyps armoured with large microbasic euryteles scattered on the hydranth body, hypostome, and female spadix; female gonophores on normal hydranths with a reduced number of tentacles. The new species is compared to other Eudendrium with similar cnidome, and other Caribbean species, including those described by Allman (1877). Among the latter, E. gracile, E. laxum, E. attenuatum, and E. tenellum (sensu Allman) are considered as species inquirenda due to the lack or the unsuitability of the type materials and the inconclusive original descriptions. Eudendrium exiguum, E. eximium, and E. fruticosum were also studied and demonstrated to be different from E. klausi sp. nov.

Abstract:

The ecology of Eudendrium spp. from the Brazilian coast is poorly known, although it already proved to be useful and important as a tool to solve some taxonomical problems of the genus. The seasonality and reproduction patterns of a population of Eudendrium caraiuru Marques & Oliveira, 2003 were studied. Data were sampled from test panels immersed in the water off Cabelo Gordo de Dentro beach, in São Sebastião Channel, Southeastern Brazil, from July 1999 to July 2000, every three months. Eudendrium caraiuru was active throughout the study period. Reproductive peaks of the species were regulated by cold and low-salinity water, although part of the population always bore mature gonophores. In addition to morphological differences, ecological differences between E. caraiuru and its similar species, E. glomeratum Picard, 1951, especially from well known populations of the Mediterranean Sea, corroborated that these species are diverse lineages of a unique ancestor.

Abstract:

The purpose of this note is to describe a new species of the hydrozoan Eudendrium found during an ecological study at the coastal lagoon Bahía de Chengue, near the city of Santa Marta, Colombia (Alvarez-Leon et al., 1995). Colonies of 6–16 cm height were collected between September 1982 and March 1983, up to 0.6 m deep. As of February 2016, this species was still present in the region. They grow on stilt roots of the red mangrove, Rhizophora mangle, in the lagoon channel, and near the opening of Cienaga Grande de Santa Marta estuary. This species is similar to the more common Caribbean Eudendrium carneum Clarke, 1882, but differs in the morphology of female and male gonophores. Voucher material is deposited in the Senckenberg Museum in Frankfurt, Germany (SMF) and in the Makuriwa-Museo de Historia Natural Marina de Colombia at Instituito de Investigaciones Marinas y Costeras—INVEMAR, Santa Marta (INV-CNI).

Abstract:

Eudendrium caraiuru sp. n. is described for the southeastern coast of Brazil. The species was reported previously from the area as E. glomeratum, a common species of the Mediterranean Sea. However, morphological, morphometrical and ecological data suggest they are diverging lineages, requiring a new specific name for the Brazilian population.

Abstract:

Two new species of hydroids, Eudendrium bleakneyi and Halecium praeparvum, are described from the Bay of Fundy. Fourteen others, Tubularia acadiae Petersen, 1990, Coryne pusilla Gaertner, 1774, Sarsia lovenii (M. Sars, 1846), Zanclea implexa (Alder, 1856), Corydendrium dispar Kramp, 1935, Rhizogeton fusiformis L. Agassiz, 1862, Bougainvillia muscus (Allman, 1863), Rhizorhagium roseum M. Sars, in G.O. Sars, 1874, Hydractinia symbiolongicarpus Buss & Yund, 1989, Eudendrium vaginatum Allman, 1863, Tiaropsis multicirrata (M. Sars, 1835), Obelia bidentata S.F. Clark, 1875, Halecium marsupiale Bergh, 1887, and Sertularella gigantea Hincks, 1874, are reported, with collection data, for the first time from the bay. All but Coryne pusilla, Rhizorhagium roseum, Eudendrium vaginatum, and Sertularella gigantea are also new to Atlantic Canada, while Zanclea implexa, Corydendrium dispar, and Halecium marsupiale are reported for the first time in the western North Atlantic. Two of those species, Hydractinia symbiolongicarpus and Obelia bidentata, are disjunct in distribution, with core populations occurring in warmer waters to the south of Cape Cod, Massachusetts. Both were discovered in Minas Basin, a hydrographically distinct embayment where surface water temperatures are much warmer during summer than in the perpetually cold lower Bay of Fundy. Rhizorhagium roseum and the subfamily Rhizorhagiinae are transferred from family Bougainvilliidae Lütken, 1850 to Pandeidae Haeckel, 1879. An annotated checklist of hydroids from the Fundy region, based on previously published reports and on new records of species, is added as an appendix. Included in the checklist are 43 species of anthoathecates and 75 species of leptothecates, referable to 30 families and 56 genera. Families with the most species were Sertulariidae (23), Haleciidae (13), Eudendriidae (11), and Obeliidae (10). Biogeographically, the aggregate hydroid fauna of the bay conforms with that occurring in other parts of the Western Atlantic Boreal Region. Halecium permodicum is proposed as a replacement name for Halecium minor Fraser, 1935, an invalid junior homonym of H. minor Pictet, 1893.

Abstract:

Thirty colonies of Eudendrium carneum and 100 colonies of E. glomeratum, collected on recruitment panels in São Sebastião (SP, SE Brazil), were studied concerning morphometrical parameters and compared with morphometrical data available from other locations. The results show that E. carneum from Brazil has a relatively smaller morphometric variation than colonies of E. glomeratum for Brazil and other areas. Both morphological and speciation causes are suggested as possible explanations for the high variation of E. glomeratum.

Full text

Abstract:

Eudendrium moulouyensis is a zooxanthellate hydroid originally described from the Chafarinas Islands (Alboran Sea, south-western Mediterranean) in summer 1991. According to the original description, this species can be identified due to the occurrence of symbiotic zooxanthellae in the entire endodermal layer of the colony (gastrodermis and tentacle endodermis), a unique feature among the Mediterranean Eudendrium species. However, several aspects of its life cycle and the extent of its phenotypical variability are still unknown. Since winter 2004, colonies of E. moulouyensis were recorded throughout the year from 0.5 m to 30 m depth from the southern Adriatic Sea (Otranto Channel) and the Gibraltar Strait (Alboran Sea). Additional specimens were collected from the northern Adriatic (Vis, Croatia), Sicily Channel (Pantelleria and Lampedusa Islands), and western Sardinia (Costa Paradiso). These findings offered the opportunity to describe for the first time the full life cycle and to elucidate several biological aspects related to phenotypical variation of colony morphology, vertical zonation, seasonality, zooxanthellae–polyp relationship, and cnidome morphology and distribution. The number and morphology of male gonophores per reproductive polyp is described here for the first time, providing a useful taxonomic character to easily discriminate Myrionema amboinense from E. moulouyensis. From the available information, the occurrence of M. amboinense in the Mediterranean Sea should be regarded as doubtful, if they are not accompanied by observations of cnidome, male gonophores or distinctly separate tentacles whorls.

Abstract:

Hydroids were examined in collections from a biological survey of Northumberland Strait undertaken by Fisheries and Oceans Canada from June to August 1975. No investigations have been undertaken previously on hydroids of the study area. Forty-eight species referable to 12 families were present in the samples, with Sertulariidae dominating in both numbers of species (12) and frequency. Gonophores were found in 30 of the species. As usual in hydroids of higher latitudes, a majority of those represented do not have a medusa stage in their life cycle. Gonophores in 42 of the 48 species are known to be fixed sporosacs while free medusae or medusoids occur in only six. Two major species groups were distinguished in a numerical analysis of hydroid species/station data. One of these groups included the three most ubiquitous species (Calycella syringa, Hydrallmania falcata, Sertularia latiuscula) together with 15 others most prevalent in samples from shallower (<20 m) and warmer stations. The second group included species occurring primarily in samples from stations in deeper (>20 m) and mostly colder waters. Two species (Lafoeina tenuis, Halecium lankesteri) are new to the Atlantic coast of North America. Eight others (Bougainvillia sp., Eudendrium dispar, Eudendrium ramosum, Cuspidella humilis, Opercularella pumila, Halecium scutum, Halecium sessile, Diphasia fallax) are reported in the southwestern Gulf of St. Lawrence for the first time. The subtidal hydroid fauna in open waters of Northumberland Strait is a cold-water assemblage typical of the boreal zone in the western North Atlantic, and no relict warm-temperate species were found.

Abstract:

Paracaprella pusilla MAYER, 1980 is a tropical caprellid amphipod species first described from Brasil and very common along the Atlantic coast of Central America. Since its original description, P. pusilla has been found at numerous widespread locations in tropical and subtropical seas around the world, primarily associated with fouling communities in harbours. An established population of P. pusilla was recently found in Cádiz, southern Spain, which is both the northernmost collection and first record of this species in European coastal waters. Ship fouling is the most probable vector for its introduction. The species was always found associated with the native hydroid Eudendrium racemosum (CAVOLINI, 1785) and appeared to display a mutualistic relationship with this host.

Abstract:

Some examples of relationships between hydroids and epibionthic diatoms from the Mediterranean Sea are described, verifying the kind of interaction existing between the two partners. The athecate Eudendrium racemosum hosts an extremely rich diatom assemblage, mainly comprising Licmophora spp., Amphora spp. and Cocconeis spp. On the contrary, only adnate growth forms (Cocconeis pseudonotata, C. dirupta) were observed in diatom communities growing on the external side of thecate species Campanularia hincksii, Clytia linearis and Synthecium evansi. Some diatom species (Cocconeis notata, Cylindrotheca sp. and Navicula sp.) are able to survive in the intrathecal microenvironment. They live in the narrow space between hydrotheca and polyp, receiving protection and probably using the nutrients produced by hydroid metabolism. Sunlight can penetrate through transparent thecae and reach the diatom layer, making photosynthesis possible.

Abstract:

The exposure to discharging nematocysts of the eolid nudibranch Cratena peregrina feeding on polyps of the hydroid Eudendrium racemosum was examined. The smaller size-class of microbasic eurytele mastigophor nematocysts is located on the tentacles of the hydroid polyps, while the larger size-class of holotrichous isorhiza nematocysts is located on long cnidophores and basal rings of some polyps. Discharging nematocysts of the tentacles do not appear to have damaging effects on the dorsal appendages of the snail, the cerata. In contrast, contact of a cnidophore with a ceras elicits massive discharge of nematocysts, which results in adherence, membranolysis and local destruction of the epidermis within seconds. The differential locations and effects indicate that the small tentacle nematocysts serve for capturing prey, while the large cnidophore nematocysts serve for the hydroid's defence. Both small and large, discharged and intact nematocysts were found in the pharynx and stomach of the snail after feeding. Thus, the alimentary tract appears to be efficiently protected against discharging nematocysts. Small and large intact nematocysts, which were capable of discharge, were also found in the cnidosacs.

Abstract:

Predation occurs when an organism completely or partially consumes its prey. Partial consumption is typical of herbivores but is also common in some marine microbenthic carnivores that feed on colonial organisms. Associations between nudibranch molluscs and colonial hydroids have long been assumed to be simple predator–prey relationships. Here we show that while the aeolid nudibranch Cratena peregrina does prey directly on the hydranths of Eudendrium racemosum , it is stimulated to feed when hydranths have captured and are handling prey, thus ingesting recently captured plankton along with the hydroid polyp such that plankton form at least half of the nudibranch diet. The nudibranch is thus largely planktivorous, facilitated by use of the hydroid for prey capture. At the scale of the colony this combines predation with kleptoparasitism, a type of competition that involves the theft of already-procured items to form a feeding mode that does not fit into existing classifications, which we term kleptopredation. This strategy of subsidized predation helps explain how obligate-feeding nudibranchs obtain sufficient energy for reproduction from an ephemeral food source.

Abstract:

Despite the hydroid fauna of the Mediterranean Sea being considered one of the best known in the world, the eastern basin of the Mediterranean Sea remains nearly unexplored. This paper reports on 38 species collected along the Levant Sea coast (mainly Lebanon), of which three are new records for the Mediterranean and nine for the Levant Sea. Six alien species, i.e. Eudendrium carneum, Sertularia marginata, Sertularia techocarpa, Macrorhynchia philippina, Diphasia digitalis and Dynamena quadridentata, are described in detail and illustrated on the basis of Levant Sea material. The last four species are considered as immigrants from the Red Sea. The synonymy of Sertularia stechowi, described from Japan, with S. techocarpa is established. Taken as a whole, the collection comprised a majority of circum-(sub)tropical species, and a reduced proportion of Atlantic–Mediterranean elements and Mediterranean endemics. The ecology (seasonality, depth distribution and habitat preference) of the indigenous species resulted similar to what is known for the more studied western Mediterranean, with some exceptions. Adding the present species inventory to the scanty published information, the total of hydroid species known from the Levant Sea rises to 70, indicating the need for future investigation in this sector of the Mediterranean Sea.

Abstract:

A recent collection of shallow-water hydroids from Guadeloupe and Les Saintes, in the eastern Caribbean Sea, was studied. This is the first comprehensive report on the hydroid fauna from the study area. A total of 48 species, belonging to 9 families of athecates and 12 families of thecates, are described or listed. All the species are illustrated and, when necessary, data on the cnidome composition are provided. Two new species, Zanclea migottoi sp. nov. and Halopteris vervoorti sp. nov., are described. Rhizogeton sterreri (Calder, 1988) is redescribed based on fertile material. Its taxonomic status is discussed and the genus Rhizodendrium Calder, 1988 is included in the synonymy of Rhizogeton L. Agassiz, 1862. Scandia michaelsarsi (Leloup, 1935) is believed to be a synonym of S. gigas (Pieper, 1884), and morphological arguments are provided to support this hypothesis. An undescribed type of peculiar gonothecae, arising from the hydrothecal apertures, was found in Dynamena disticha (Bosc, 1802). Sertularella peculiaris (Leloup, 1935) is redescribed and its synonymy discussed. The nematocyst types of Symmetroscyphus intermedius (Congdon, 1907) were identified. Some species in the present collection are provisionally identified or assigned to a genus, pending the discovery of fertile material or additional life cycle studies. Finally, the hydroid fauna from the study area proves to be preponderantly tropical in nature, with several species also occurring in temperate seas. A number of species are first records for the Caribbean basin: R. sterreri, Eudendrium capillare Alder, 1856, Coryne pusilla Gaertner, 1774, Halecium cf. lankesteri (Bourne, 1890), S. gigas, and Sertularia loculosa Busk, 1852.

Abstract:

An account is given of 48 species identified in a small collection of hydroids from the west coast of Sweden. Assigned to39 genera and 18 families, most are well-known from boreal waters of the North Atlantic Ocean. Campanulina paniculaG.O. Sars, 1874 is referred to Racemoramus, a new genus of leptothecates distinguished in part by having monopodialgrowth, rigid and non-segmented hydrocauli, and grape-like clusters of hydrothecae that arise at irregular intervals fromthe stem. The name Sertularia dumosa (now Lafoea dumosa) is taken to have been made available by Fleming (1820), notFleming (1828). As such, it is not threatened by a virtually unused subjective synonym (Lafoea cornuta Lamouroux,1821). Aselomaris michaeli Berrill, 1948 and Rhizorhagium navis Millard, 1959 are regarded as synonyms and combinedunder the binomen Pachycordyle michaeli (Berrill, 1948). Confusion in the literature over the identity of Sertularia teneraG.O. Sars, 1874 is addressed, and distinctive characters of the species are discussed. A species often misidentified as S.tenera is assigned to Sertularia spitzbergensis (Jäderholm, 1909); the name spitzbergensis is elevated in rank from sub-specific to specific, and assigned priority over its simultaneous synonym siberica Jäderholm, 1909 under the First ReviserPrinciple. Gonothecae of Clytia gigantea (Hincks, 1866) (type locality: Lamlash Bay, UK) are reported for the first timein material from Europe. Although much like Clytia hemisphaerica, this species is retained as valid due to its remarkablyrobust colony form, elongate and gradually tapered hydrothecae, and linguiform rather than wavy or pointed marginalcusps. Eudendrium album Nutting, 1896, Pachycordyle michaeli (Berrill, 1948), and the hydroid stage of Halitholus cir-ratus Hartlaub, 1913 are reported for the first time from the study area. A checklist of hydroids from the study area is included.

Abstract:

Fourteen species of hydroids, collected during August 2019 by ROV SuBastian of the Schmidt Ocean Institute, are reported from the Emperor Seamount chain in the western North Pacific Ocean. Two others, Candelabrum sp. and Eudendrium sp., were observed only on videos taken by the ROV. From collections and video observations, eight species of hydroids were found at Jingū Seamount, three at Yomei, Nintoku, and Annei seamounts, and one at Koko Seamount and Hess Rise. At Suiko and Godaigo seamounts, hydroids were seen in videos but they could not be identified. Latebrahydra schulzei, an endobiotic associate of the hexactinellid sponge Walteria flemmingii Schulze, 1886 from Annei Seamount and Hess Rise, is described as a new genus and species tentatively attributed to Hydractiniidae L. Agassiz, 1862. Another new species, Hydractinia galeai, is described from Jingū Seamount. Among its distinctive characters is a zooid termed a sellectozooid, likely serving in both food capture and defence. Hydroids examined from Yomei, Nintoku, and Jingū seamounts are elements of a cold-water fauna occurring in the North Pacific Boreal Bathyal province, while those of Annei and Koko seamounts, and Hess Rise, are part of the biota of the Central North Pacific Bathyal province. Hydroids identified as Bouillonia sp., from Nintoku Seamount, represent the first record of this predominantly deep water tubulariid genus in the North Pacific Ocean. Bonneviella superba Nutting, 1915, from Jingū Seamount, is reported for the first time outside the Aleutian Islands. Bonneviella cf. gracilis Fraser, 1939, known elsewhere only from Dease Strait in the western Canadian Arctic, was also collected on Jingū. In addition to hydroids, medusae of Ptychogastria polaris Allman, 1878 were observed on videos from Nintoku, Jingū, Annei, and Koko seamounts at depths between 2423–1422 m. An unidentified siphonophore was observed near bottom at 2282 m on Nintoku Seamount.

Abstract:

A systematic account is given of 17 families, 25 genera, and 32 species of anthoathecate hydroids and limnopolyps reported from Hawaii. Applying Reversal of Precedence provisions in zoological nomenclature, the familiar hydrozoan genus names Hydractinia Van Beneden, 1844a, Bimeria Wright, 1859a, and Porpita Lamarck, 1801 are designated as valid and as nomena protecta, while seldom-used older names threatening them (the synonyms Echinochorium Hassall, 1841 and Manicella Allman, 1859a, and the homonym Porpita Soldani, 1789 respectively) are relegated to nomena oblita. Also designated a nomen oblitum is the name Pyxidium Leuckart, 1856, threatening its junior but widely used synonym Ectopleura L. Agassiz, 1862. The species name Bimeria vestita Wright, 1859a is rendered valid and a nomen protectum, while its virtually unused senior synonym Manicella fusca Allman, 1859 becomes a nomen oblitum. Hydrodendrium Nutting, 1905 is reinstated as a valid genus, distinct from Hydractinia and replacing its junior objective synonym Nuttingia Stechow, 1909. The spelling of Hydrodendridae Nutting, 1905 is emended to Hydrodendriidae, but that family name is retained as a synonym of Hydractiniidae. Usage of the familiar generic name Sphaerocoryne Pictet, 1893 is upheld by recognizing it and its former senior subjective synonym Corynetes Haeckel, 1879 as valid. The correct spelling of the family name originally founded as Olindiadae Haeckel, 1879 is taken to be Olindiidae, and spelling of the species name Solanderia misakinensis (Inaba, 1892), first established as Dendrocryne (sic) misakii, is stabilized. One new species, Stylactaria munita, is described from shallow waters at Hawaii Kai, Oahu. Lectotypes are designated for Corydendrium corrugatum Nutting, 1905 and Corydendrium minor Nutting, 1905 (=Turritopsis minor), both originally described from Hawaii. Type material of Balea mirabilis Nutting, 1905 (=Balella mirabilis), originally described from waters between the islands of Molokai and Maui, could not be located. Six anthoathecate species [Corydendrium parasiticum (Linnaeus, 1767), Bimeria vestita, Amphinema sp., Eudendrium carneum Clarke, 1882, Ectopleura viridis (Pictet, 1893), and Sphaerocoryne bedoti Pictet, 1893] are recorded from Hawaii for the first time.
