Ecology of Eretmochelys imbricata
 
Main Ref. Schneider, W., 1990
Remarks Most often seen in shallow waters around reefs, bays, and inlets (Ref. 122680). Turtles measuring up to 10 cm straight carapace length are usually nektonic animal. It changes to benthic feeding when it approaches coastal areas. This is a carnivorous turtle commonly poking in crevices between rocks and corals. It feeds on algae, ascidians, sponges, bryozoans, molluscs, hydroids, barnacles, cephalopods, salps, and seagrasses (Ref. 97534). It becomes a regular inhabitant of hard substrata, i.e., corals, tunicates, algae and sponges (Ref. 417). Associated with reef fishes (Ref. 104964) and a shrimp (Ref. 104967).

Associations

Ref. Schneider, W., 1990
Associations symbiosis;
Associated with reef fishes Acanthurus chirurgus, Acanthurus coeruleus, Acanthurus coeruleus, Acanthurus nigrofuscus, Ctenochaetus strigosus, Zebrasoma flavescens, Ophioblennius trinitatis, Thalassoma duperrey, Thalassoma lunare, Abudefduf saxatilis, Abudefduf sexfasciatus, Stegastes rocasensis (Ref. 104964) and Pomacentrus paru (Ref. 104970); Shrimp Stenopus hispidus (Ref. 104967).
Association remarks Reef fishes forage on the epibionts of the turtle, exhibiting cleaning symbiosis (Ref. 104964). This association is also observed between a barber pole shrimp and E. imbricata (Ref. 104967).
