Pehmusteisista

Pehmusteisista, also known as soft-shelled turtles, are a group of turtles characterized by their soft, leathery shells. This group includes both marine and freshwater species, and they are found on every continent except Antarctica. Pehmusteisista are known for their unique shell structure, which is composed of a series of bony plates covered by a thin layer of horny material. This shell is not as rigid as that of hard-shelled turtles, allowing for greater flexibility and mobility.

The most well-known pehmusteisista are the sea turtles, which include species such as the green sea turtle, the leatherback sea turtle, and the hawksbill sea turtle. These turtles are adapted to life in the ocean and have streamlined bodies and flippers for swimming. They are also known for their long migrations, during which they travel thousands of miles between feeding and nesting grounds.

Freshwater pehmusteisista, on the other hand, are found in rivers, lakes, and ponds. They have shorter, more rounded shells and are adapted to life in freshwater environments. Examples of freshwater pehmusteisista include the red-eared slider and the painted turtle.

Pehmusteisista are an important part of many ecosystems, serving as both predators and prey. They play a crucial role in maintaining the balance of their environments. However, many species of pehmusteisista are threatened by habitat loss, pollution, and climate change. Conservation efforts are underway to protect these unique and valuable creatures.
