The term 'Cousin of Croc' can be solved by the five-letter word 'GATOR'. The American alligator is a close relative of the crocodile, and is commonly referred to as a 'cousin of croc'. Alligators are native to the southeastern United States, and are found in freshwater rivers, lakes, and swamps. They are large reptiles, with adults growing up to 4.5 meters in length. Alligators are carnivorous, and feed on fish, birds, and small mammals.
