Abstract:

The anatomy of the suction disk of two species of echeneid fishes, Echeneis naucrates L., 1758 and E. neucratoides Zuiew, 1786, is described, and measurements of their suction performance on both smooth and textured surfaces are given. Disk muscles erect or depress the numerous paired laminae, or toothed plates, which bear two to four rows of posteriorly directed spinules. The erect laminae create a sub-ambient chamber, allowing these fishes to adhere to other fish and inanimate objects. Resting sub-ambient suction pressure differentials were recorded, as were the greatest sub-ambient pressure differentials as the fish were pulled posteriorly to simulate drag induced by a swimming host. The resting pressure differential averaged –0.5 kPa, with no significant difference between Plexiglas® and shark skin surfaces. With a force applied to their caudal peduncle, the echeneids generated suction pressure differentials averaging –92.7 kPa within the disk cavity while attached to Plexiglas. On shark skin, the use of spinules increased friction and reduced the maximum sub-ambient suction pressure differential to –46.6 kPa; considerably more force (17.4 N) was required to dislodge the echeneids from the shark skin than from the smooth Plexiglas (11.2 N).

Abstract:

Abstract Carcharhinus brevipinna (spinner) and Carcharhinus limbatus (blacktip) sharks make spectacular jumps and spinning leaps out of the water. Some believe these are: jumping responses to rid sharksuckers (Echeneis naucrates) that attach to their bodies, chaffing, shuttling, or heat hunter- cool rest behaviors. Examination of North Carolina shark data suggests that C. brevipinna and C. limbatus in temperate waters of North Carolina sense changes in abrupt ocean water temperatures. Echeneis naucrates is just along for the ride. Why after fourty-six years of longlining only one Echeneis naucrates occurred on C. brevipinna while many occurred on C. limbatus is unknown. Perhaps something in the skin texture, not shape, of C. brevipinna deters Echeneis from attaching.

Abstract:

An overview is presented for a poorly documented relationship between reef vertebrates in Southwest Atlantic: remoras (Echeneidae) associated with marine turtles. Two remora species (Echeneis naucrates and Remora remora) and four turtle species (Caretta caretta, Chelonia mydas, Eretmochelys imbricata, and Dermochelys coriacea) are here recorded in symbiotic associations in the SW Atlantic. Echeneis naucrates was recorded both on the coast and on oceanic islands, whereas R. remora was recorded only at oceanic islands and in the open sea. The remora-turtle association is usually regarded as an instance of phoresis (hitchhiking), albeit feeding by the fish is also involved in this symbiosis type. This association seems to be rare in SW Atlantic.

Full text

Abstract:

A phylogenetic analysis, based on 138 putatively informative characters, of the 11 species of the superfamily Echeneoidea (Echeneidae, Rachycentridae, and Coryphaenidae) resulted in a single most parsimonious tree. This tree strongly supports the monophyly of the superfamily with the following relationships: Coryphaenidae + (Rachycentridae + (Phtheirichthys lineatus + ((Echeneis naucrates + Echeneis neucratoides) + (Remora brachyptera + (Remora remora + (Remora australis + (Remora osteochir + Remora albescens))))))). One of the traditional subfamilies, Echeneiinae, and one of the traditional genera, Remora, were both found to be paraphyletic. A new classification of the family based on natural groupings eliminated the subfamilial designations and subsumed the genus Remorina under the genus Remora, rendering it monophyletic. An examination of the behavioural data resulted in the hypothesis of a gradual step-by-step development of "hitchhiking" behaviour from general schooling behaviour (outgroups) to attaching to a select few types of hosts in the pelagic environment (as exhibited by R. osteochir).

Full text

Abstract:

This study used field data of echeneid and ectoparasite associations with free-swimming whale sharks (Rhincodon typus) and captured mako sharks (Isurus oxyrinchus) to test whether (1) echeneid presence was positively correlated with ectoparasite presence; and (2) the number of ectoparasites was negatively correlated with the number of echeneid fish. Data from whale and mako sharks do not support the first hypothesis whereas data from mako sharks yields support for the second hypothesis. The results indicate that echeneids do regulate the number of ectoparasites on at least some host species, but these benefits may be contingent on the echeneid species.

Abstract:

The single record of the sharksucker (Echeneis naucrates) attached to a spinner dolphin (Stenella longirostris) is based on a photograph taken at Fernando de Noronha Archipelago, off northeast Brazil. A careful examination of this photograph demonstrates that the diskfish attached to the dolphin is the whalesucker (Remora australis), a species so far recorded on cetaceans only. Thus, the record of S. longirostris as a host for E. naucrates is here invalidated and the value of vouched records is reiterated. The exaggerated reliance even on refereed papers dealing with species records and checklists that lack or have dubious vouchers and their further use is commented upon.

Full text

Abstract:

1. Ram ventilation has been demonstrated in rainbow trout, Salmo gairdneri. The swimming speed eliciting the transition in mode of ventilation increased with declining ambient water oxygen tension (PwOO2). 2. The mode of ventilation of fish swimming at a constant speed could be altered by controlled variations in PwOO2. 3. Oxygen consumption (V·OO2) decreased by 10.2% when rainbow trout, swimming at a constant speed, shifted from active to ram ventilation. This difference can be ascribed to a lowering of the energetic cost of active ventilation as well as improved drag characteristics. 4. Water velocity required for the transition from active to ram ventilation in the resting sharksucker, Echeneis naucrates, increased with decreasing PwOO2. 5. The results show that water oxygen tension is an important stimulus for setting the ventilatory mode in rainbow trout and sharksucker.

Full text

Abstract:

The relationship between phoretic diskfishes and their hosts is a classic example of marine symbiosis, yet surprisingly few studies have quantified this trophic relationship. We investigated the hypothesis that by consuming host parasites and prey scraps phoretic diskfishes (Echeneidae) feed at a higher relative trophic position than free-living individuals through expanded foraging opportunities. We used carbon and nitrogen stable isotope analysis of muscle tissue from both free-living and commensal sharksuckers Echeneis naucrates and their hosts, supplemented with gut-content analysis, to investigate this hypothesis. Our analysis revealed that commensal sharksuckers likely occupy higher relative trophic positions than free-living sharksuckers. The importance of scavenging host prey decreased ontogenetically as sharksuckers shifted from symbiotic phoresis to free-swimming behavior, leading to an ontogenetic change in which obligately commensal juveniles occupy higher trophic positions than free-living adults which are only facultatively commensal. Relative differences in δ13C and δ15N among individual host-commensal pairs varied among host species, suggesting potential differences in foraging opportunities among host taxa.

Abstract:

Sea bream Spams aurata L. and sea bass Dicentrarchus labraxL. were sampled from three different locations in Greece (2 cage fish farms located in different geographic areas and a lagoon), in order to investigate the prevalence of Metazoa parasites, the intensity and the factors associated with the prevalence. In farm 1 (Eastern Greece) the prevalence of the ectoparasites was: 61.5% and 76.9% for Monogenea, 0% for Isopoda and 0% and 23% for Copepoda in sea bream and sea bass, respectively. In farm 2 the prevalence was: 13.3% and 26.3% for Monogenea, 13.7% and 20% for Isopoda and 0% and 13.6% for Copepoda in sea bream and sea bass, respectively. Lesions in the gills of Sparidae were due to monogeneans, but lesions in the skin and eyes were due to Ceratothoa oestroides larval stages causing severe pathology. Furnestinia. echeneis and Diplectanum aequans were host specific for sea bream and bass, respectively and showed persistence in all aquaculture systems. The Greek lagoon had the largest variety of parasites among the ecosystems studied, however, this variety did not significantly affect the health of infected fish. Lernanthropus kroyeri was host specific and was detected only in sea bass in both cage farms investigated.

Abstract:

Abstract Remora suckerfish (Echeneis naucrates) can perform skimming and sliding motions on the surfaces of moving hosts to optimize adhesion positions. We found that remora achieve skimming and sliding motions through coordinated movement of the suction disc’s lamellae and lip locomotion through live animal observations. We implemented an integrated biomimetic remora suction disc based on morphological and kinematic data of biological remoras. With soft actuators enabling ‘compression–rotation’ and ‘compression–extension’, the biomimetic disc controls the disc lip and lamellar movement under driving with only one degree of freedom, and can switch freely between three states: zero, low-friction, and robust adhesion. Then we investigate the effects of the biomimetic suction-disc soft-lip material, preload, and lamellar movement on the tangential friction force (both forward and backward) under different adhesion states. This biomimetic suction disc with a low-modulus soft lip can adhere to a smooth surface under 0.1 N preload and achieve normal adhesion-force and tangential frictional-force control ranges spanning ∼10−1 to ∼102 N and ∼10−1 to ∼101 N, respectively. The results reveal how remora disc achieved fast, tunable adhesion for skimming and sliding on surfaces. Furthermore, we demonstrate a bio-inspired robot capable of attachment, detachment, skimming, and sliding motions with the aiding of simple biomimetic pectoral-fin flapping. This study lays a foundation for future integrated applications of underwater adhesion robots and related biomechanical exploration.

Full text

Abstract:

Despite being among the largest and most charismatic species in the marine environment, considerable gaps remain in our understanding of the behavioural ecology of manta rays (Mobula alfredi, M. birostris). Manta rays are often sighted in association with an array of smaller hitchhiker fish species, which utilise their hosts as a sanctuary for shelter, protection, and the sustenance they provide. Species interactions, rather than the species at the individual level, determine the ecological processes that drive community dynamics, support biodiversity and ecosystem health. Thus, understanding the associations within marine communities is critical to implementing effective conservation and management. However, the underlying patterns between manta rays, their symbionts, and other hitchhiker species remain elusive. Here, we explore the spatial and temporal variation in hitchhiker presence with M. alfredi and M. birostris throughout the Maldives and investigate the factors which may influence association using generalised linear mixed effects models (GLMM). For the first time, associations between M. alfredi and M. birostris with hitchhiker species other than those belonging to the family Echeneidae are described. A variation in the species of hitchhiker associated with M. alfredi and M. birostris was identified, with sharksucker remora (Echeneis naucrates) and giant remora (Remora remora) being the most common, respectively. Spatiotemporal variation in the presence of manta rays was identified as a driver for the occurrence of ephemeral hitchhiker associations. Near-term pregnant female M. alfredi, and M. alfredi at cleaning stations, had the highest likelihood of an association with adult E. naucrates. Juvenile E. naucrates were more likely to be associated with juvenile M. alfredi, and a seasonal trend in E. naucrates host association was identified. Remora were most likely to be present with female M. birostris, and a mean number of 1.5 ± 0.5 R. remora were observed per M. birostris. It is hoped these initial findings will serve as the basis for future work into the complex relationships between manta rays and their hitchhikers.

Abstract:

The ecology of mantas and echeneids in the Tropical Eastern Pacific is poorly understood. In this study we describe the frequency of interactions between the vulnerable Mobula birostris and its symbiont Remora remora based on observations of scientists and tourists in a marine protected area. Data were obtained by analysing underwater photographs of observed mantas with remoras over 139 diving days at sea during the period 2016–17. In all, there were 271 photographic records of this symbiosis, corresponding to 207 mantas, with a mean (±s.d.) of 1.6±0.6 remoras per manta. This study is the first to provide information regarding the sex ratio, length, morphotype frequency and echeneids per manta of M. birostris in the Tropical Eastern Pacific.

Full text

Abstract:

ABSTRACTRemoras (echeneid fish) reversibly attach and detach to marine hosts, almost instantaneously, to “hitchhike” and feed. The adhesion mechanisms that they use are remarkably insensitive to substrate topology and quite different from the latching and suction cup-based systems associated with other species at similar length scales. Remora adhesion is also anisotropic; drag forces induced by the swimming host increase adhesive strength, while rapid detachment occurs when the remora reverses this shear load. In this work, an investigation of the adhesive system’s functional morphology and tissue properties was carried out initially through dissection and x-ray microtomographic analyses. Resulting finite element models of these components have provided new insights into the adaptive, hierarchical nature of the mechanisms and a path toward a wide range of engineering applications.

Abstract:

The adhesion disc of living remoras (Echeneoidea: Echeneidae) represents one of the most remarkable structural innovations within fishes. Although homology between the spinous dorsal fin of generalized acanthomorph fishes and the remora adhesion disc is widely accepted, the sequence of evolutionary—rather than developmental—transformations leading from one to the other has remained unclear. Here, we show that the early remora † Opisthomyzon (Echeneoidea: †Opisthomyzonidae), from the early Oligocene (Rupelian) of Switzerland, is a stem-group echeneid and provides unique insights into the evolutionary assembly of the unusual body plan characteristic of all living remoras. The adhesion disc of † Opisthomyzon retains ancestral features found in the spiny dorsal fins of remora outgroups, and corroborates developmental interpretations of the homology of individual skeletal components of the disc. † Opisthomyzon indicates that the adhesion disc originated in a postcranial position, and that other specializations (including the origin of pectination, subdivision of median fin spines into paired lamellae, increase in segment count and migration to a supracranial position) took place later in the evolutionary history of remoras. This phylogenetic sequence of transformation finds some parallels in the order of ontogenetic changes to the disc documented for living remoras.

Abstract:

Abstract Suckerfish attached to dolphin species have been extensively reported worldwide, yet such association has been rarely seen in the tropical and shallow waters of South America. In Brazil, the Guiana dolphin Sotalia guianensis is distributed along almost the entire extent of the coast and only one case of association with suckerfish has been published. Here we report on a sharksucker Echeneis naucrates associated with a young Guiana dolphin on the north-eastern coast of Brazil. The juvenile dolphin with an attached sharksucker was observed on two occasions separated by a 47-day period; we hypothesize the occurrence of host attachment fidelity. The present report adds information to better discuss the ecological interactions between echeneids and dolphins, and expands the baseline information on cetacean species serving as host to suckerfish.

Abstract:

AbstractExaminations of materials of trichinelloid nematodes recently collected from the digestive tract of marine fishes off New Caledonia, South Pacific, revealed the presence of several species of the families Capillariidae and Trichosomoididae, including capillariids Pseudocapillaria novaecaledoniensis sp. nov. from the deep-sea Pristipomoides argyrogrammicus (Valenciennes) (Lutjanidae) and Pseudocapillaria echenei (Parukhin, 1967) from Echeneis naucrates Linnaeus (Echeneidae), and the trichosomoidid Huffmanela sp. (female) from Bodianus perditio (Quoy et Gaimard) (Labridae). P. novaecaledoniensis is characterized mainly by the structure and length (318–321 µm) of spicule and the presence of a dorsal cuticular membrane interconnecting both ventrolateral caudal lobes in the male (subgenus Ichthyocapillaria Moravec, 1982). The previously poorly known P. echenei is redescribed and recorded for the first time from the South Pacific Ocean. In addition, five morphologically different types of capillariid females without generic identification, designated as Capillariidae gen. spp. 1–5, each of them probably representing a new species, were recorded from Fistularia commersonii Rüppell (Fistulariidae), Synodus dermatogenys Fowler (Synodontidae), Carangoides oblongus (Cuvier) (Carangidae), Diagramma pictum (Thunberg) (Haemulidae) and Stegostoma fasciatum (Hermann) (Stegostomidae), respectively. Capillaria decapteri is transferred to Pseudocapillaria Mendonça, 1963 as P. decapteri (Luo, 2001) comb. nov.

Abstract:

AbstractEcheneis naucrates, as known as live sharksucker, is famous for the behavior of attaching to hosts using a highly modified dorsal fin with oval-shaped sucking disc. Here, we generated an improved high-quality chromosome-level genome assembly of E. naucrates using Illumina short reads, PacBio long reads and Hi-C data. Our assembled genome spans 572.85 Mb with a contig N50 of 23.19 Mb and is positioned to 24 pseudo-chromosomes. Additionally, at least one telomere was identified for 23 out of 24 chromosomes. Furthermore, we identified a total of 22,161 protein-coding genes, of which 21,402 genes (96.9%) were annotated successfully with functions. The combination of ab initio predictions and Repbase-based searches revealed that 15.57% of the assembled E. naucrates genome was identified as repetitive sequences. The completeness of the genome assembly and the gene annotation were estimated to be 97.5% and 95.4% with BUSCO analyses. This work enhances the utility of the live sharksucker genome and provides a valuable groundwork for the future study of genomics, biology and adaptive evolution in this species.

Abstract:

Hybrid aerial–aquatic robots can operate in both air and water and cross between these two. They can be applied to amphibious observation, maritime search and rescue, and cross‐domain environmental monitoring. Herein, an aerial–aquatic hitchhiking robot is proposed that can fly, swim, and rapidly cross the air–water boundaries (0.16 s) and autonomously attach to surfaces in both air and water. Inspired by the mechanoreceptors of the remora (Echeneis naucrates) disc, the robot's hitchhiking device is equipped with two flexible bioinspired tactile sensors (FBTS) based on a triboelectric nanogenerator for tactile sensing of attachment status. Based on tactile sensing, the robot can perform reattachment after leakage or adhesion failure, enabling it to achieve long‐term adhesion on complex surfaces. The rotor‐based aerial–aquatic robot, which has two thrust vectoring units for underwater locomotion, can maneuver to pitch, yaw, and roll 360° and control precision motion position. The field tests show that the robot can continuously cross the air–water boundary, attach to the rough stone surface, and record video in both air and underwater. This study may shed light on future autonomous robots capable of intelligent navigation, adhesion, and operation in complex aerial–aquatic environments.

Abstract:

Many real-world applications for robots—such as long-term aerial and underwater observation, cross-medium operations, and marine life surveys—require robots with the ability to move between the air-water boundary. Here, we describe an aerial-aquatic hitchhiking robot that is self-contained for flying, swimming, and attaching to surfaces in both air and water and that can seamlessly move between the two. We describe this robot’s redundant, hydrostatically enhanced hitchhiking device, inspired by the morphology of a remora ( Echeneis naucrates ) disc, which works in both air and water. As with the biological remora disc, this device has separate lamellar compartments for redundant sealing, which enables the robot to achieve adhesion and hitchhike with only partial disc attachment. The self-contained, rotor-based aerial-aquatic robot, which has passively morphing propellers that unfold in the air and fold underwater, can cross the air-water boundary in 0.35 second. The robot can perform rapid attachment and detachment on challenging surfaces both in air and under water, including curved, rough, incomplete, and biofouling surfaces, and achieve long-duration adhesion with minimal oscillation. We also show that the robot can attach to and hitchhike on moving surfaces. In field tests, we show that the robot can record video in both media and move objects across the air/water boundary in a mountain stream and the ocean. We envision that this study can pave the way for future robots with autonomous biological detection, monitoring, and tracking capabilities in a wide variety of aerial-aquatic environments.
