It has an almost an elastic texture to touch as well as a somewhat flexible shell, instead of having a bony, hard one, which is made of scutes, thick plates that other sea turtles have.

 

Turtle journeys

 

There are incredible long migrations that sea turtles make between breeding and feeding areas. The leatherback, for example, goes approximately 3,700 miles each way. Female leatherbacks dig a hole onto the shore after they are got mated at sea, to lay their eggs. Then they settle their eggs (up to one hundred), cover them back up, then get back to the sea.

 

The eggs hatch after about 2 months, at night, the young turtles move from the beach into the sea. That journey would be full of dangers as these tiny babies can be hunted by crabs, seabirds, and other predators. Also, sea turtles could be confused and heading the wrong way because of the homes, hotels, and other buildings’ lights. However, the hatchings can be guided to the sea by natural light on the horizon.

 

Extreme threats

There are many practices that make 6 of the 7 these species are assorted as critically endangered, endangered, or threatened such as climate change, pollution, bycatch in fishing nets, and humans hunting. The outcome of the hatchlings’ sex is affected during the hot weather as the sand they’re laid in gets warmer.
