Although the taxonomy varies, there are three families of crocodilians: alligatoridae alligators and caimans , crocodylidae "true crocodiles" and gavialidae gharial. Alligators and caimans Alligatorids possess a characteristically broad snout and upper jaws that normally overlap their lower jaws, hence hiding their lower teeth which fit into depressions in the upper jaw.
Crocodylids have a more V-shaped snout in general, with both upper maxillary and lower mandibular teeth interdigitating outside the jaw ie. Gavialids have the most slender or longirostrine jaw of any species, specially adapted to sweeping through water to catch fish.
All crocodilians possess " integumentary sense organs ", which appear as dark spots, across the scales of their upper and lower jaws. This gives many species a somewhat "unshaven" appearance when viewed up close, and lends them an unprecedented ability to detect small vibrations and movement through water and across the ground.
However, while these spots are present all over the body scales of crocodylids and gavialids, they are absent from the bodies of alligatorids. Which crocodilian species make the best captives? Are there laws against keeping crocodilians?

These caimans tend to do better in smaller surroundings for the first month or two.
As the caiman grows and is feeding well, the accommodations will need to be larger. A 55 gallon or gallon aquarium would be the next best size. Every habitat should have an area with a basking spot. This area could be as simple as a rock, a piece of floating cork bark, a piece of fixed driftwood or a combination of cork bark, driftwood, rocks and plants.
We use a day light bulb during the day and a heat light bulb at night in the basking area. The wattage of the light will depend on the size of the tank. Ceramic heat emitters may also be used instead of the lights.
