Résumé :
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).

Résumé :
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.

Résumé :
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.

Canadian Journal of Zoology 80, no 4 (1 avril 2002) : 596–623. http://dx.doi.org/10.1139/z02-031.

Texte intégral
Résumé :
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).

Résumé :
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.

Résumé :
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.

Résumé :
In this paper Hybrid Meotipa Pulcherrima-Echeneis Neucratoides (HMPEN) optimization algorithm are applied for solving true power loss reduction problem. In the proposed Meotipa Pulcherrima inspired optimization (MPIO) algorithm at the commencement of exploration, the concept of decent opinions is utilized to acquire the enhanced preliminary populace and it assist the procedure to swiftly define the accurate exploration way. At that juncture, quadratic exclamation approach is utilized to progress the solution accurateness and quicken the convergence. In the meantime, to evade the procedure tumbling into local optima, wavelet alteration is presented to progress populace multiplicity and supports the procedure to pursuit the global optima. In the Exploration segment Echeneis Neucratoides attached with Istiophorus and its location can be measured as the Istiophorus position. Subsequently in minor comprehensive drive, Echeneis Neucratoides will equate appropriateness standards of Stratagem and familiarity endeavor to elect whether to swap the horde. The location with a minor appropriateness rate is engaged in Echeneis Neucratoides Optimization (ENO) Algorithm. Both the Meotipa Pulcherrima inspired optimization algorithm and Echeneis Neucratoides Optimization Algorithm are hybridized to enhance the search. Through this Hybridized Meotipa Pulcherrima-Echeneis Neucratoides Exploration and Exploitation has been balanced. Better refined solutions have been obtained.
