As soon as it entered the water the young Olive Ridley Sea Turtle (Lepidochelys olivacea) struggles against the waves to swim away from the coast. The swimming frenzy lasts for approximately 48 hours to keep the hatchlings from being washed ashore. The turtles do not feed within the first days as they live on the reserves they acquired from the yolk in their eggs. The swimming hatchlings often fall prey to Frigatebirds or larger fish.
