Caimans vary in size from one meter for the dwarf caiman to almost five meters for the black caiman. They are most closely related to alligators and crocodiles.

Females build large nests and lay anywhere from 10 to 50 eggs which hatch in about six weeks. The temperature determines the gender of the babies.

Piranhas are omnivorous and will eat almost anything that it can find. Its diet mainly consists of snails, insects, fish, and aquatic plants.

They are usually found in fast flowing rivers where there is enough food to go around. Since piranhas live in large shoals, competition for food is fierce and feeding frenzies can occur when there is blood in the water or when a shortage of food occurs. In April and May, piranhas mate. They move, in pairs, to slower moving waters and prepare a nest. The female then lays an average of 5000 eggs of which, usually 90 percent survive.
