In spite of their sluggish visual appearance, crocodiles are top predators in their surroundings and a variety of species are noticed attacking and killing sharks. Crocodiles typically feed on vertebrates like fish, reptiles, and mammals, from time to time with invertebrates like molluscs and crustaceans, based upon species.
Put up-Cranial: While alligators and caimans have DPRs only on their jaws, crocodiles have very similar organs on virtually every scale on their bodies. The function from the DPRs to the jaws is evident; to catch prey, but it is even now not apparent what the perform is on the organs on the remainder of the physique. The receptors flatten when exposed to greater osmotic stress, which include that knowledgeable when swimming in sea h2o hyperosmotic to the body fluids.
It really is believed that this crocodile species feeds on fish, insects, crabs, and snails but absolutely nothing changes The actual fact that they're opportunistic and feed on animals remaining within just their selection.
There isn't any reputable way of measuring the age of a crocodile, While several tactics can be employed to derive an affordable guess.

Though crocodiles, alligators, as well as gharial are equivalent in visual appearance, they belong to independent Organic people. The gharial, with its narrow snout, is less complicated to tell apart, when morphological variations are tougher to identify in crocodiles and alligators.

The armoured skin has scales and is also thick and rugged, giving some protection.
