1. Leatherback sea turtle (Dermochelys coriacea)

 

The leatherback sea turtle (Dermochelys coriacea) is the largest living turtle species and one of the most unique in appearance.

Here are some details about this fascinating creature:

Size: Leatherbacks can reach lengths of up to 2 meters (6.6 feet) and weigh as much as 700 kg (1,500 pounds). They have a streamlined body shape that helps them swim efficiently in the open ocean.

Appearance: Leatherbacks have a unique look compared to other turtle species. They lack a hard, bony shell and instead have a leathery skin that is covered in tough, flexible plates that resemble armor. These plates, known as "dermal bones," are made of tiny, overlapping bones that are covered in a thick layer of connective tissue. The turtle's back and sides are black or dark brown, while the underside is white or pale pink.

Habitat: Leatherbacks can be found in all of the world's oceans, from the tropics to the subarctic. They are highly migratory and can travel thousands of kilometers each year to find suitable breeding and feeding grounds.

Diet: Leatherbacks are carnivores and feed almost exclusively on jellyfish. They have special adaptations in their throat and digestive system that allow them to swallow large, gelatinous prey without getting stung by the jellyfish's tentacles.

Threats: Leatherbacks face a number of threats in the wild, including habitat loss, hunting, accidental capture in fishing gear, and ingestion of plastic pollution. Climate change is also a significant threat, as rising temperatures can disrupt nesting patterns and affect the turtles' food sources.

Conservation status: Leatherbacks are listed as "Vulnerable" by the International Union for Conservation of Nature (IUCN), which means they are at high risk of extinction in the wild. Conservation efforts include protecting nesting beaches, reducing accidental capture in fishing gear, and raising awareness about the importance of reducing plastic pollution in the ocean.
