What animals live and the sea land?

It sounds like you're asking about animals that live in both the sea and on land! There aren't many animals that can do that, but here are a few examples:

* Sea Turtles: These reptiles spend most of their lives in the ocean, but they come ashore to lay their eggs.

* Sea Snakes: Some sea snakes are entirely marine, but others can spend time on land.

* Marine Iguanas: Found in the Galapagos Islands, these lizards are the only known marine lizards and spend time swimming in the ocean for food.

* Crabs: Many crabs live in the ocean, but some species are adapted to life on land, like the Coconut Crab.

* Amphibians: While most amphibians are freshwater, there are a few species of sea frogs that live in the ocean.

It's important to remember that these animals are still adapted to a primarily aquatic life. They may come ashore for certain purposes like breeding or basking in the sun, but they rely on the ocean for their food and shelter.
