Abstract (sommario):
Nudibranchia are mollusks without a shell. They are simultaneous hermaphrodites and are carnivores while some of them are cannibals. Nudibranchia are frequent occupants and foraging on coral reefs. The study was conducted at two locations, namely Waleo Village Waters representing the waters of Mollucas and Sulawesi Sea was represented by Kalasey Village. The difference in the location of the two waters is expected to affect the existence of community structures. The present study includes diversity, richness, evenness, dominance and similarity. A line transect was used to collect data. We found 84 individuals from both study sites representing 8 species of Nudibranchia, which fall into 4 genera and 3 families namely, Pteraeolididae, Phyllidiidae, and Chromodorididae. The most common family was the Phyllidiidae. The similarity value at both locations was 54.5%© Penelitian tentang struktur komunitas gastropoda nudibranchia telah dilakukan di dua lokasi yaitu Desa Waleo (Laut Maluku) dan Desa Kalasey (Laut Sulawesi). Struktur komunitas yang dikaji meliputi studi keanekaragaman, kekayaan, kemerataan, dominansi dan kesamaan. Metode yang digunakan dalam penelitian adalah line transect. Hasil penelitian menunjukkan, dari kedua lokasi, ditemukan 84 individu yang terdiri dari 8 jenis yang masuk dalam 4 genera dan 3 famili (Pteraeolididae, Phyllidiidae, dan Chromodorididae).

Abstract (sommario):
Nudibranchia is the largest order of Opistobranchia which is known to have about 3,000 species. Nudibranchia is a popular macro photography object among divers. Although Tulamben Waters, Bali is one of popular destination for macrobiota’s habitat, but research on marine biota, especially nudibranchia in these waters is still very rare. This study uses two methods, which is direct observation to reveal diversity and species number, belt transect methods to estimate density or abundance per sampling area using diving techniques . A transect line of 50 m at each point of observation site was used to evaluate abundance. This study wants to see the level of diversity, mapping various species and abundance of nudibranchia. For biodiversity, 31 species from 15 families are found, Chromodoridae, Dorididae, Elysiidae, Facelinidae, Flabellinidae, Goniodorididae, Halgerdidae, Hexabranchidae, Phyllidiidae Polyceridae, Hydatinidae, Costasiellidae, Elysiidae and Limapontiidae. Whereas the transect method found 12 species from 6 families, Chromodoridae, Facelinidae, Phyllidiidae Aglajidae, Costasiellidae, and Elysiidae. With a diversity index of 2.27 and the highest level of abundance found in Pteraeolidia ianthina species with a relative abundance of 0.19%.

Abstract (sommario):
Pantai Penimbangan terletak Desa Baktiseraga, Kecamatan Buleleng merupakan kawasan pusat kota Kabupaten Buleleng, Bali yang memiliki hamparan pasir hitam. Kegiatan konservasi penyu di kawasan ini meningkatkan gairah masyarakat dalam menjaga kelestarian ekosistem terumbu karang. Salah satu biota yang beriteraksi di ekosistem terumbu karang adalah nudibranch. Keberadaan nudibranch di Pantai Penimbangan diharapkan mampu menjadi alternatif potensi wisata yang bisa dikembangkan, sehingga antusiasisme masyarakat untuk menjaga kelestarian ekosistem pesisir akan terus terjaga. Penelitian bertujuan untuk memperkuat data dasar ekologi tentang keanekaragaman dan kelimpahan nudibranch. Penelitian populasi nudibranch dinilai dengan sensus visual mengikuti line intercept transect. Penelitian nudibranch di Pantai Penimbangan menunjukkan bahwa terdapat 12 famili yaitu Chromodorididae, Phyllidiidae, Discodorididae, Aeolidiidae, Elysiidae, Aglajidae, Bornellidae, Facelinidae, Flabellinidae, Hexabranchidae, Limapontiidae, dan Pleurobranchidae, dengan 42 jenis. Kelompok Chromodorididae dan Phyllidiidae adalah kelompok yang umum dijumpai di Perairan Pantai Penimbangan. Kedua kelompok ini memanfaatkan patahan karang yang menjadi subsrat perairan sebagai tempat berlindung. Komposisi substrat sangat menentukan kekayaan nudibranch, kategori substrat yang menentukan keberadaan nudibranch adalah dead coal with alga, sponge, dan hard coral. Tingginya persentase dead coral with alga, dan sponge berbanding lurus dengan keanekaragaman nudibranch, dan hard coral berbanding terbalik dengan keanekaragaman nudibranch. Kriteria indeks keanekaragaman tinggi dengan nilai 2,6199, Indeks keseragaman 0,7055 dan nilai dominansi 0,0342. Tingkat kelimpahan tertinggi pada jenis Hypselodoris tryoni. Penimbangan Beach is located in Baktiseraga Village, Buleleng District, which is the downtown area of Buleleng Regency, Bali which has a stretch of black sand. Turtle conservation activities in this area increase the enthusiasm of the community in preserving the coral reef ecosystem. One of the biota that interacts in the coral reef ecosystem is the nudibranch. The existence of nudibranchs at Penimbangan Beach is expected to be an alternative tourism potential that can be developed, so that public enthusiasm for preserving coastal ecosystems will continue to be maintained. This study aims to strengthen the basic ecological data on the diversity and abundance of nudibranchs. The study of the nudibranch population was assessed by visual census following the line intercept transect. Research on nudibranchs at Penimbangan Beach showed that there were 12 families namely Chromodorididae, Phyllidiidae, Discodorididae, Aeolidiidae, Elysiidae, Aglajidae, Bornellidae, Facelinidae, Flabellinidae, Hexabranchidae, Limapontiidae, and Pleurobranchidae, with 42 species. Chromodorididae and Phyllidiidae groups are common groups found in Penimbangan Beach. Both of these groups take advantage of coral fractures which become the substrate of the waters as a shelter. Substrate composition greatly determines the richness of nudibranchs, the substrate categories that determine the presence of nudibranchs are dead coral with algae, sponges, and hard corals. The high percentage of dead coal with algae, and sponges is directly proportional to nudibranch diversity, and hard coral is inversely proportional to nudibranch diversity. The criteria for the high diversity index are 2.6199, the uniformity index is 0.7055 and the dominance value is 0.0342. The highest abundance level was in Hypselodoris tryoni.

Abstract (sommario):
With the complexity of the family Phyllidiidae and the problems of identification in the Indo-West Pacific, the story of the Red Sea species continues to unfold. One new species and one new record are added to the Red Sea fauna, both belonging to the genus Phyllidiella. Phyllidiella amphitritesp. nov. is described from a single specimen from the northern Red Sea and clearly differs from all species of Phyllidiella in having pale yellow pigment on the tubercles. Phyllidiella zeylanica is newly recorded from the Red Sea with five specimen records and several photographed individuals; other than this, it has a western Indian Ocean distribution. Phyllidia schupporum was collected for the first time since its original description; because its distribution is now extended to the Persian Gulf, it is no longer considered endemic to the Red Sea. The distribution of the Red Sea endemic Phyllidia dautzenbergi is extended northwards to Hurghada, Egypt. A small specimen of the endemic Phyllidiopsis sinaiensis was found at 214–237 m depth just at the mouth of the Red Sea, which is a bathymetrical range extension from its previous shallow coral reef records. The identifications of other species are revisited. A new species of Paradoris is described as Paradoris hypocritasp. nov., differing from the well-known but localised West Pacific P. liturata which also resembles a phyllidiid. This new species was recorded many years ago by published photographs, and it is relatively common in the Red Sea, evidenced by several specimens and additional photographs. It is described herein, and is considered a Red Sea endemic, differing from both the unnamed Indian Ocean species and the named Pacific species.

Abstract (sommario):
AbstractMembers of the widely distributed and common nudibranch family Phyllidiidae are often easily spotted in the marine environment because of their conspicuous colours and obvious presence on the reef. They are interesting with regard to their defensive chemical compounds that may lead to new drug discoveries. Despite their abundance, the family is also well known for its taxonomic problems and the difficulties in species identification due to very similarly coloured species and lack of morphological characters. In this study, phyllidiid species were analysed using an integrative approach. Molecular analysis of the mitochondrial genes 16S and CO1 was utilised, running phylogenetic analyses, species delimitation tests, and haplotype network analyses. Additionally, for the first time, external morphological characters were analysed, museum material was re-analysed, and chemical profiles were applied for characterising species. The analyses are based on sequences of 598 specimens collected in Indonesia by the team, with the addition of published sequences available on GenBank. This study comprises 11 species of Phyllidia, seven species of Phyllidiopsis, and at least 14 species of Phyllidiella. Moreover, 11 species belonging to these three genera are probably new to science, Phyllidiopsis pipeki is synonymised with P. krempfi, and Phyllidiella albonigra is resurrected. Some of the external colouration previously used for species identification is shown to not be valid, but alternative characters are provided for most species. Chemical analyses led to species characterisation in a few examples, indicating that these species use particular sponge species as food; however, many species show a broad array of compounds and are therefore characterised more by their composition or profile than by distinct or unique compounds.

Abstract (sommario):
Abstract Phyllidiid nudibranchs are brightly colored gastropod molluscs, frequently encountered in coral reefs of the tropical Indo-Pacific. This study aimed to identify the phylogenetic similarities among the Phyllidia spp. The phylogenetic similarities among all the available Phyllidia spp. were studied by comparing the nucleotide sequence of 16s rRNA and cytochrome c genes (cox I). Sequences were retrieved from NCBI databases and aligned by using Geneious software. A phylogenetic tree was constructed for the retrieved sequences of Phyllidia spp. by using the neighbor-joining method on MEGA software and the pairwise distances were also calculated. The similarities among nucleotide sequences of 16s rRNA showed that the P. elegans, and P. haegeli had the highest similarities (99.92%) and the lowest similarities (99.14%) among P. haegeli and P. picta. While nucleotide sequences of cox I showed the highest similarities (99.90%) between P. elegans and P. ocellata, and the P. varicosa had the lowest similarities 99.74% with P. koehleri and P. larryi. The molecular phylogenetic analysis based on mitochondrial marker indicated a close relation between P. elegans and P. alyta in both cox I and 16s rRNA phylogenetic tree. The phylogenetic tree of 16s rRNA gene shows the P. ocellata is closely related to the clade of species P. exquisita. The available phylogenetic analysis could be useful in further studies of Phyllidiidae within Nudibranchia.

Abstract (sommario):
AbstractIn the present study, we compared mucus and gut-associated prokaryotic communities from seven nudibranch species with sediment and seawater from Thai coral reefs using high-throughput 16S rRNA gene sequencing. The nudibranch species were identified as Doriprismatica atromarginata (family Chromodorididae), Jorunna funebris (family Discodorididae), Phyllidiella nigra, Phyllidiella pustulosa, Phyllidia carlsonhoffi, Phyllidia elegans, and Phyllidia picta (all family Phyllidiidae). The most abundant bacterial phyla in the dataset were Proteobacteria, Tenericutes, Chloroflexi, Thaumarchaeota, and Cyanobacteria. Mucus and gut-associated communities differed from one another and from sediment and seawater communities. Host phylogeny was, furthermore, a significant predictor of differences in mucus and gut-associated prokaryotic community composition. With respect to higher taxon abundance, the order Rhizobiales (Proteobacteria) was more abundant in Phyllidia species (mucus and gut), whereas the order Mycoplasmatales (Tenericutes) was more abundant in D. atromarginata and J. funebris. Mucus samples were, furthermore, associated with greater abundances of certain phyla including Chloroflexi, Poribacteria, and Gemmatimonadetes, taxa considered to be indicators for high microbial abundance (HMA) sponge species. Overall, our results indicated that nudibranch microbiomes consisted of a number of abundant prokaryotic members with high sequence similarities to organisms previously detected in sponges.

Abstract (sommario):
AbstractDorid nudibranchs are a large group of mollusks with approximately 2,000 recorded species. Although agreement exists on the monophyletic nature of the dorid nudibranch group, the interfamily relationships of the suborder are subject to debate. Despite efforts to elucidate this issue using short molecular markers, the conclusiveness of the findings has been hindered by branching polytomy. Mitogenomes are known to be effective markers for use in phylogenetic investigations. In this study, eight mitogenomes of dorid nudibranchs were decoded and analyzed. Gene content and structure showed little change among species, reflecting the conserved mitogenomes of dorid nudibranchs. For most genes, the direction was typical for nudibranchs; nevertheless, tRNACys had an inverse direction in Cadlinidae species. Phylogenetic trees based on nucleotide and amino acid datasets revealed a relatively consistent pattern of interfamily relationships with little difference for positions of Phyllidiidae and Cadlinidae. Species of Cadlinidae were clustered together and did not form a clade with Chromododidae. Additionally, Goniodorididae was sister to Aegiridae, whereas Discodoridae was sister to Dorididae. This finding was supported by tree topology test based on mitogenome data. The results of the present study indicate that complete mitogenomes are promising markers for investigating interfamily relationships among dorid nudibranchs.

Abstract (sommario):
The family Dendrodorididae has a global distribution, with prevalence in tropical and subtropical intertidal zones. Three species of Dendrodorididae were collected from the intertidal zone of the northern coast of the Persian Gulf in Iran. Based on anatomical, histological, and molecular investigations they can be assigned to Dendrodoris fumata, Dendrodoris nigra, and a new species of Doriopsilla, D. aroni sp. nov. Molecular analyses of CO1 and 16S, including all genera of Dendrodorididae, members of the sister taxon Phyllidiidae, and other dorid outgroups resulted in a polyphyletic genus Dendrodoris, which is in contrast to the nuclear gene studies. Our molecular results confirm the differentiation between Dendrodoris rubra and D. fumata. Dendrodoris nigra, D. fumata, and D. krusensternii each consist of several clades, indicating cryptic species complexes requiring further investigation. We describe the presence of bacteria for the first time in the vestibular gland of D. fumata. Validation of the specimens of Doriopsilla from the Persian Gulf as a new species is supported by haplotype networking, genetic distance, and ABGD analyses of mitochondrial genes. Our CO1 analysis confirms a previous hypothesis that Cariopsilla is a junior synonym of Doriopsilla.

Abstract (sommario):
Siput laut memiliki manfaat ekologi, ekonomi, dan menjadi objek penting dalam penelitian di berbagai disiplin ilmu. Sebagai bagian dari gastropod yang berasosiasi dengan organisme sesil, siput laut menjadi indikator yang baik untuk kesehatan habitat di perairan. Belum ada penelitian mengenai siput laut di Bangsring Underwater dan Pulau Tabuhan. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis kelimpahan dan keanekaragaman spesies siput laut (Opisthobranchia) di lokasi tersebut. Pengambilan data dilakukan di 9 lokasi penyelaman. Data siput laut diambil menggunakan belt transect dan fotografi bawah air di kedalaman 0 sampai 10 m (dikateogikan sebagai dangkal) dan >10 sampai 18 m (dikategorikan sebagai dalam). Identifikasi dilakukan melalui foto bawah air dengan melihat morfologi, warna, bentuk rhinophores, notum (punggung), kaki, dan insang. Waktu pengambilan data dimulai pada bulan November sampai dengan Desember 2020. Hasil penelitian menunjukkan bahwa ditemukan 85 spesies dalam 19 famili dan 3 ordo (Nudibranchia, Sacoglossa, dan Cephalaspidea). Famili paling beragam adalah Chromodorididae (29% dari total spesies) dan Phyllidiidae (19%) dari ordo Nudibranchia. Frekwensi temuan spesies terbanyak adalah spesies P. pustulosa dan P. briareum. Keanekaragaman tertinggi terdapat di Rumah Apung dangkal dengan nilai H’= 4,2 sedangkan keanekaragaman terendah terdapat di Tabuhan Selatan dengan nilai H’= 1,0. Kelimpahan tertinggi terdapat di Zona inti dangkal dengan nilai 23 ind/200 m2, sedangkan kelimpahan terendah terdapat di Tabuhan Selatan, Tabuhan Timur, dan Tabuhan Barat dengan nilai yang sama yaitu 1 ind/200 m2.

Abstract (sommario):
Phyllidiid Nudibranchs Phyllidia varicosa and Phyllidiella pustulosa were observed under laboratory conditions and abnormal behaviours were recorded. This study described the manoeuvering, mating behaviour, egg laying and abnormal activities. Some abnormal behaviours were recorded while retaining the sample in the aquarium such as emitting noxious chemicals, lifting up the mantle edge to expose the gills and crawling towards the water surface and lie there. Maneuvering behaviour was distinguished when two individuals were interacting with each other before the mating. Mating behaviour started by extending and joining the reproductive organs followed by gamete exchange for several minutes. During the mating behaviour, there was a limited movement like contracting of the body and hiding the rhinophores into the rhino-tube. Egg deposition was observed in the aquarium as natural behavior after mating and as a stress response after placing the sample in the captivity.

Abstract (sommario):
Based on an examination of 41 dorid nudibranch species (Gastropoda: Opisthobranchia: Anthobranchia: Doridina) we report the existence of intra-individual variation in the distribution of different spicule types in various parts of the integument of nudibranchs. Interspecific variation in spicule morphology is also described and compared. Twelve species of the family Phyl-lidiidae were examined and all possessed spicules. Phyllidiid spicules showed considerable morphological diversity, and par-ticular spicule types were localised in specific parts of the body, in contrast to all the other families. Of the 19 species of the Chromodorididae examined, only Cadlinella ornatissima (Risbec, 1928) contained spicules. Of the remaining species from other families, only the discodorids Halgerda rubicunda Baba, 1949 and Platydoris formosa (Alder Hancock, 1864), the dorid Aldisa albatrossae Elwood et. al., 2000, and the hexabranchid Hexabranchus sanguineus (Rüppell Leuckart, 1830) possessed spicules.
