“…We believe that this generally also applies to G. ocellatus, since during a very dark moonless night dive, fish baits tightly sealed inside clear plastic bags failed to attract sand morays before opened. The knotting behavior reported here for G. ocellatus was already described by Miller (1987Miller ( , 1989 for four other genera and eight species of muraenid eels. We thus regard G. ocellatus as a carcinophagous-piscivorous nocturnal predator feeding on bottom prey, located primarily by the sense of smell.…”

“…If the dead fishes were smaller than about 25% of the moray's length, they were quickly swallowed whole. If larger, the morays applied the knotting behavior (see Miller 1987Miller , 1989) to bend the fish or remove pieces from it (Fig. 3).…”

Activity, habitat utilization, feeding behaviour, and diet of the sand moray Gymnothorax ocellatus (Anguilliformes, Muraenidae) in the South western Atlantic.The sand moray Gymnothorax ocellatus is a nocturnal predator from the western South Atlantic that actively forages on the bottom, preying mostly on crustaceans (mainly shrimps and crabs) and ray-finned fishes, which are located primarily by the sense of smell. The individuals stay stationary during the day, almost always being hidden in individual tunnels dug by animals other than the morays in the muddy sand bottom.Key words: Muraenidae; Gymnothorax ocellatus; habitat use; feeding behaviour; diet.

Os indivíduos permanecem inativos durante o dia, quase sempre escondidos em túneis individuais escavados por outros animais, que não moréias, em substrato areno-lodoso. Palavras

“…Morays using casitas did not appear to control the abundance of co-occurring lobsters and lobsters were virtually absent in stomach contents of morays. These morays have been observed feeding on lobsters previously killed by other predators (Weiss et al 2006), but morays in general tend to respond quickly to chemical cues from dead or injured animals irrespective of their size (Bardach et al 1959, Miller 1989). In contrast, Gymnothorax morays use visual cues to select live animals that they can swallow 181 whole (Miller 1989, Fishelson 1997, Metha & Wainwright 2007.…”

The Caribbean spiny lobster Panulirus argus is a valuable fishing resource, but local populations may be limited by availability of crevice shelter on juvenile (seagrass) habitats. This has prompted research into the potential density enhancement of juvenile lobsters with 'casitas', large (1.1 m 2 surface area) but low-lying (3.8 cm entrance height) artificial shelters that exclude large predators. Moray eels (Muraenidae), however, fit into casitas and could therefore pose a threat to lobster enhancement. In a shelter-poor reef lagoon, we examined potential interactions between juvenile lobsters and the locally dominant morays Gymnothorax vicinus and G. moringa in the absence (four 1 ha control sites) and presence of casitas (five 1 ha 'casita sites', each with 10 casitas), before (6 surveys) and after (22 surveys) deployment. Morays and lobsters did not interact as predator-prey, as morays neither consumed nor intimidated co-occurring lobsters. Rather, the 2 taxa appeared to compete for limited shelter on the reef lagoon, as suggested by a significant increase in density and mean size of both taxa on casita sites after deployment. Casitas significantly increased cohabitation of morays and lobsters, yet they tended to co-occur less often than expected by chance, but this result likely reflects behavioral differences between the highly gregarious, more numerous lobsters and the typically solitary, cannibalistic morays. Our study exemplifies the influence of habitat complexity on the nature of interspecific interactions and shows that G. vicinus and G. moringa would not pose a threat to lobster enhancement with casitas.

“…Otherwise, the food item will rotate with the twisting predator [2]. This behavior has been observed in crocodilians [3], caecilians [4], and a few groups of fishes including anguillids [5], muraenids [6], and representatives of a few other families [1]. Most fish species for which rotational feeding has been reported are anguilliform or have an attenuated body.…”

Neogobius melanostomus, the round goby, was recorded by underwater video feeding on crushed dreissenid mussels at a depth of 12 m in Georgian Bay of Lake Huron, a Laurentian Great Lake. In the video, gobies used rotational or twist feeding to tear away particles from crushed mussels. At least 43 examples of this feeding maneuver occur in the video. Up to 120 gobies m −2 were visible at a time in the video. Mean standard length of gobies appearing in the video was 37 mm. Mean standard length of fish exhibiting twist feeding was larger, 48 mm. Mean size of intact mussels in visible clusters was about 10 × 20 mm, a size which exceeds the gape width of the largest gobies observed in the video. Neogobius melanostomus is known to use twisting to wrest small attached mussels from the substrates which can be crushed by their pharyngeal teeth. I surmise that the behavior observed in the video is an opportunistic manifestation of this inherent behavioral adaptation to overcome gap limitation and exploit a temporary windfall of food.
