Crocodile

Crocodiles are enemies that appear in Tomb Raider, Tomb Raider: Unfinished Business, Tomb Raider III, Tomb Raider IV and Tomb Raider Anniversary.

Tactics
They swim but can follow you onto land as well. Fairly easy to avoid so just keep you riddance and keep shooting them.

Beta
Some earlier screenshots of Tomb Raider show Crocodiles appearing in the Lost Valley level. In the final version, Crocodiles do not appear in Peru. Only in Greece and Egypt.
