Leatherbacks have downward pointing spines in their throat, which allows jellyfish to be swallowed, but prevents them from coming back up. Typical Lifespan: Leatherbacks reach maturity at approximately 13 to 14 years. Their average lifespan is unknown, but itâs thought to be at least 30 years. Habitat: Leatherbacks spend most of their lives at sea and sometimes look for prey in coastal waters.
Estimated numbers left in the wild: 60,000 (very approximate). Leatherback sea turtles are the largest turtles in the world, and are fourth in size among all current reptiles. Their body is protected only by leathery, oily skin, rather than a hard shell. The leatherbackâs front flippers can grow to a spread of 2.7 meters, and the animal itself measures from 1.8 to 2.2 meters long.
