The loggerhead turtle has a large head and powerful jaws built for crushing hard-shelled prey like crabs and conches. Females often return to lay their eggs on the very beach where they hatched, sometimes decades earlier.
What defines this group — Sea turtles
Reptiles that went back to the sea: they breathe air and return to lay eggs on the beach where they hatched.
Lungs, not gills: they have to surface to breathe.
The front limbs have become paddles, and the shell can no longer tuck them away.
Females find their way back to their birth beach, sometimes across thousands of kilometres.
