As a Pet

The container for the pet should be large enough, though it need not be very tall, as this variety of lizard does not climb largely. The minimum recommended size of wooden or glass terrarium is 2×4 feet and 8×4 feet for larger pets. One end the container should have a soaking or swimming pan for the lizard to submerge in filtered and heated water. You should use an Aquatic Heater with thermostat setting of 25 – 28° C and an Aquarium internal filter for the purpose. You can make the land or dry area from coir or forest bark, providing cork tubes or caves, sufficiently big for the lizards to coil up at the cooler end of the terrarium.

You would do well to maintain the following features about temperature and humidity

•    Basking spots (use a basking spot lamp) – Temperature of 32-35 degrees C

•    Cooler temperatures – 25-28 degree C with 21-24 degrees C at night

•    Control the temperatures with a pulse thermostat


The large Northern Caiman Lizard is carnivorous and hunts prey mainly for nutrient sustenance. Although their main foods are snails, they will also eat other invertebrates like crabs, insects and larger animals like amphibians, rodents and fish.

Surprisingly, they also like hard-boiled eggs, can O’ snails, rats, mice, chicks, Goliath hornworms, canned jumbo krill, mangoes, grapes, banana, peach, apples and the like. Variety is the key of their diet.

There is not much recorded evidence about the breeding habits of the Northern Caiman Lizard, although many experts feel that their behavior in this regard will have a similarity with those of the other species of large lizards. Post mating, the females dig a hole in the substrate, deposit their eggs in it, and cover it up in protection. Normally, in their original habitat, they bury their eggs in the sand in riverbanks to prevent access to predators. The babies, when they hatch, are independent, and get no maternal care from their mother.
