A crocodile (family Crocodylidae) or true crocodile is a large, semiaquatic reptile that lives throughout the tropics in Africa, Asia, the Americas and Australia. The term "crocodile" is sometimes used more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (both members of the family Alligatoridae), the gharial and false gharial (both members of the family Gavialidae) as well as other extinct taxa.

AI overview
A crocodile is a large, semiaquatic reptile belonging to the family Crocodylidae that lives in tropical regions across Africa, Asia, the Americas, and Australia. Though the term is sometimes used broadly to describe related reptiles like alligators and gharials, true crocodiles represent a distinct group within the larger order of crocodilian reptiles.

鳄科（学名：Crocodylidae）是鳄目下的一个科，它包括所有一般被称为鳄的动物。但是鳄这个概念在一般生活中的定义不非常确定，它往往也指所有鳄目中的动物，既也包括短吻鱷科和長吻鱷科的动物。有时这个概念甚至包括鱷形超目的所有动物，即也包括今天鳄的远古亲属和祖先。鳄是大型水生爬行动物，它们生活在非洲、亚洲、美洲和澳大利亚的热带地区。它们喜欢在淡水中如河、湖和沼泽地中聚集。有时也会生活在半海水中。有些种，比如澳大利亚的灣鱷以及东南亚和太平洋岛屿的鳄也生活在海滨。它们可以游到离海岸相当远的地方。大多数鳄吃脊椎动物如鱼、爬行动物和哺乳动物。有些种有时也吃无脊椎动物如软体动物和甲壳动物。鳄是一种非常古老的动物，从恐龙时代至今它们没有发生很大的变化。 鳄科物种分布图 鳄的学名来自希腊语，它由kroke（石头）和drilos（虫）两个部分组成。 埃及神话中的神索贝克是拥有鳄的头的。

A crocodile (family Crocodylidae) or true crocodile is a large, semiaquatic reptile that lives throughout the tropics in Africa, Asia, the Americas and Australia. The term "crocodile" is sometimes used more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (both members of the family Alligatoridae), the gharial and false gharial (both members of the family Gavialidae) as well as other extinct taxa. This article will use "crocodile" or "true crocodile" to refer only to the species taxonomically included in the Crocodylidae family, extant or extinct.
Crocodile size, morphology, behaviour and ecology differ among species. However, they have many similarities in these areas as well. All crocodiles are semiaquatic and tend to congregate in freshwater habitats such as rivers, lakes, wetlands and sometimes in brackish water and saltwater. They are carnivorous animals, feeding mostly on vertebrates such as fish, reptiles, birds and mammals, and sometimes on invertebrates such as molluscs and crustaceans, depending on species and age. All crocodiles are tropical species that, unlike alligators, are very sensitive to cold. Many species are at the risk of extinction, some being classified as critically endangered.
