in the sea? Crocodile is a common reptile. It is a very ancient and primitive animal. Crocodiles have a wide range of distribution in the world, especially in tropical and subtropical regions, because they have certain requirements for the surrounding temperature. Crocodiles can move in water, generally in fresh water. Most modern crocodiles live in fresh water, and few can live in the sea. However, in ancient times, crocodiles lived in the sea, that is to say, the ancestors of crocodiles lived in the sea, and then no longer lived in the sea due to environmental changes and other reasons. Although crocodiles no longer live in water, they also have salt glands in their body structure, which are used to expel excess salt from their bodies. Salt glands are located near the eyes of crocodiles, and when they shed tears, they are actually expelling salt.

Although most crocodiles do not live in the sea, there is one exception, that is, saltwater crocodiles, which can move in the sea and spend a long time in the sea. This crocodile is distributed in the south and southeast of Asia, and also in the coastal areas of Australia.

2. Where

do crocodiles live? Crocodiles are very ancient creatures that have existed for more than two thousand years. Crocodiles originally lived in the ocean, but now most crocodiles do not live in the sea, but in fresh water. For example, there may be some crocodiles living in rivers, lakes, swamps and other places. Only one species of saltwater crocodile, mentioned above, lives near the ocean and on the beach. In terms of latitude, crocodiles are mainly distributed in the tropics and subtropics, because they like to live in warm places. There are also some crocodiles living in temperate regions, but the number is not as large as that in tropical and subtropical regions.
