Ecology Summary - Lepidochelys olivacea

SeaLifeBase

Language:

Ecology of Lepidochelys olivacea

Main Ref.	Schneider, W., 1990
Remarks	Shallow coastal waters; open sea forming schools (Ref. 417). Habitat is a warm vertically stratified water with deep thermocline (Ref. 78527). Observed to be basking on sand beaches (Ref. 1397). Nesting patterns range from solitary to small groups to arribadas (Ref. 97534). Little information exists on the feeding behavior of post-hatchlings and juveniles in pelagic waters, but they are most likely exclusively carnivorous, consuming, for instance, invertebrates and fish eggs. Older juveniles and adults feed on a wide variety of benthic organisms (Ref. 122680).
