The Crocodile is one of the default species available for villager creation. Although there are differences between the species, both crocodiles and alligators fall under this villager. The variations in lineart are very small, having changes only in a couple teeth and iris size.
The crocodile has 4 different colors. The first three can be used upon villager creation, but the rest have to have a potion or correct color plush to be applied.
