About Sea Turtles
There are seven species of sea turtles: the Green, Loggerhead, Kemp’s Ridley, Olive Ridley, Hawksbill, Flatback, and Leatherback. Most of them are endangered, with some (such as Hawksbill) being critically endangered. Apart from Flatbacks, who are found only in the waters around Australia, all six sea turtle species are found in every ocean except the Antarctic.
Most sea turtle species live between 35 to 80 years. Some individuals, however, may exceed 200 years. Green sea turtles tend to have the longest average lifespan of 80 years. Hawksbill and the Flatbacks tend to live around 35+ years.
Sea turtles are as old as dinosaurs
Leatherback turtles were around while dinosaurs were still alive. The fossils of the oldest known sea turtle date back around 150 million years. Dinosaurs became extinct around 65 million years ago. That means they were swimming in our oceans while T.Rex was running around on land.
Leatherbacks are huge
Leatherbacks are the largest of all sea turtle species. They grow to around 1.2 to 1.9m (3.9-6.2 feet) and weight from 200 to 500kb (441 to 1,100 pounds). The biggest Leatherback found weighted 916 kg (2,019 pounds).
Leatherbacks are unlike other sea turtles
Leatherbacks are also the only sea turtle that doesn’t have a hard shell. Their carapace is rubbery to touch and is somewhat flexible. Hence, is their name – leatherback.
