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.
Recent global estimates of nesting females of the critically endangered leatherback sea turtle (Dermochelys coriacea) runs between 26,000 and 43,000.
