Because they are aquatic in the wild, they require a large source of water in captivity. Caimans are largely active at night nocturnal. They usually spend the day submerged in water, or in burrows they dig into the banks of waterways. Some caimans live in loose-knit groups, whereas others are solitary and develop small home ranges.
They have a range of communication calls such as bellows, growls and hisses. Before hatching, juveniles emit chirping calls to synchronize hatching with the other babies. Hatchlings also give distress calls when they need the protection of their parents. When threatened, some caiman species inflate their bodies to exaggerate their size, and they can also hiss loudly to scare off predators. Spectacled caimans become sexually mature at 4 — 7 years of age.
Females build a large nest of soil and vegetation which can be more than 5 ft 1. They lay 14 — 60 eggs depending on the species in the nest, and cover them with more vegetation.
Other females may share the nest, and the duty of guarding it, and are sometimes helped by males. After about 70 days, the eggs hatch. You may also feed turtle pellets or krill.
Feeder fish should be available at all times. It has been said that feeding exclusively goldfish may cause a deficiency of Vitamin E so try to feed a variety of feeder fish including bait fish such as minnows. A calcium supplement is a good idea especially in young, growing animals.
You can "gut-load" your live prey with a number of commercially available diets. A hatchling should be fed every day or two. Sub-adult dwarf caimans should be fed 2 to 3 times per week using properly sized food items.
Adults can be fed 1 to 2 times per week with properly sized food items. Try to feed a variety of prey items that can be easily swallowed whole. Adults feed on fish, frogs, tadpoles, snails, small mammals and a wide variety of insects. Their prey is usually swallowed whole or in large pieces.
Senses: Even though their skin is heavily armored, it is very sensitive, allowing them to detect physical and chemical stimuli.
As carnivores, their senses are extremely powerful — hearing can hear young call while inside the egg , eyes on top of their head, and well-developed senses of taste and smell.
Communication: They communicate through sounds, postures, movements, smells, and touch. During courtship, males make a grunting sound. Group name. Semiaquatic, Precocial, Burrowing, Ambush predator. Diet and Nutrition Cuvier's dwarf caimans are carnivores insectivores, piscivores.
Diet Carnivore, Insectivores, Piscivores. Population Trend. Least concern LC. Population Population threats Cuvier's dwarf caimans are threatened by habitat destruction, including the mining of gold, intensive agriculture, and urbanization. Population number According to IUCN, the Cuvier's dwarf caiman is locally common and widespread throughout its range but no overall population estimate is available.
Ecological niche Cuvier's dwarf caimans are very important for their ecosystem. The genus name 'Paleosuchus' is derived from the Greek and roughly translates as 'ancient crocodile'. This refers to the belief that this crocodile comes from an ancient lineage that diverged from other species of caimans some 30 million years ago.
