Caimaninaeとは 意味・読み方・使い方

Caimans are alligatorid crocodylians within the subfamily Caimaninae. The group is one of two subfamilies of the family Alligatoridae, the other being alligators. Caimans inhabit Central and South America. They are relatively small crocodilians, with most species reaching lengths of only a few meters, although one species, the Black caiman, can exceed 4 metres (13 ft) in length. Several extinct forms are known, including Purussaurus, a giant Miocene genus that grew to 12 metres (39 ft) and the equally large Mourasuchus, which had a wide duck-like snout.
