Here are some facts on the leatherback sea turtle:
– One of seven species of marine turtles in the world.
– Evolved around 100 million years ago and co-existed with the dinosaurs.
– The shell is shaped like a teardrop with seven distinct dorsal ridges tapering at the tail. – The adults that frequent Atlantic Canadian waters have an average curved carapace (shell) length of approximately 1.5 metres and an average weight of approximately 400 kilograms.
– The throat and esophagus are covered with spines, which are believed to be an adaptation to assist in swallowing slippery jellyfish prey.
