What is giant sea turtle whose back resembles an island?

The giant sea turtle whose back resembles an island is the Leatherback sea turtle. It is the largest living turtle and one of the heaviest reptiles in the world. They can grow up to 7 feet in length and weigh up to 2,000 pounds.

Leatherback sea turtles are named for their unique shell, which is made up of flexible, rubbery skin that gives it a leathery texture. Their back is covered with ridges and grooves that make it look like it has an island on its back.

These turtles have a unique diet, unlike other sea turtles that are vegetarians. They feed almost exclusively on jellyfish, which they swallow whole and digest using specialized spines in their throat.

Leatherback sea turtles are also known for their long-distance migrations, traveling up to 10,000 miles each year to feed and breed. They can dive to depths of over 4,000 feet and stay underwater for up to 85 minutes.

Leatherback sea turtles are considered an endangered species due to habitat destruction, accidental entanglement in fishing gear, and poaching for their meat and eggs. Conservation efforts are underway to protect and preserve these giant sea turtles.
