Full Answer

Sea turtles are made up of two scientific groupings: Cheloniidae and Dermochelyidae. Turtles in Cheloniidae are relatively long-lived. Green sea turtles can live up to 75 years, while loggerheads are estimated to live between 30 to 62 years in the wild. In captivity, loggerheads fare less well, with a life span up to 30 on average.

Dermochelyidae consists of one species, the leatherback. As of 2015, its maximum life span is unknown, but they are estimated to live for 30 or more years.
