Dwarf crocodiles belong to the subfamily Crocodylinae. The West African dwarf crocodile has a knob on its snout which distinguishes it from its Congolese cousin.
Crocodiles often snap at things that splash near their heads.
In this way, they easily catch their lunch in the form of a jumping frog, fish or bird that has selected a poor place to land. When zoo visitors throw coins at crocodilians, the animals may snap at and swallow the coins, and become ill. Reproduction Dwarf crocodiles become sexually mature when they are about 5 to 6 years old. The male approaches a floating female, slides onto her back and embraces her while attempting to align his cloaca with hers. If she is receptive, she opens her cloaca and he inserts his copulatory organ.
