What do crocodiles do

The short answer is yes. Saltwater crocodiles have a huge range that extends from northern Australia to eastern India and South-east Asia. As their name suggests, saltwater crocodiles are able to live in coastal habitats, but they are comfortable in freshwater rivers as well. These huge reptiles are so well adapted to life in saltwater that they are able to spend days or even weeks at sea, drifting and swimming hundreds of kilometres and possibly hunting en route.

The temperature of the nest in which eggs are laid determines the sex of the offspring. Lower incubation temperatures produce mostly females; higher temperatures mostly males. Saltwater crocodiles have long lifespans, with many living to more than 65 years, longer than any other crocodile species. In addition to protecting their eggs from potential predators, females carry new hatchlings to nearby bodies of water so that they will not be harmed during that dangerous first journey and continue to protect the young for at least several months.

Interestingly, the temperature of the nest determines the sex of the hatchlings. Cooler nests produce mostly females, while warmer nests produce mostly males. Though they have few natural predators, saltwater crocodiles have been hunted for many decades by people. Their eggs and meat are eaten, and their skin is particularly valuable for use as a material for bags, shoes, and other goods. Recent conservation efforts have allowed populations to rebound in some places, but the historic range has certainly contracted, as a result of local extinction.

Currently, the saltwater crocodile has complete legal protection in Australia and other places. However, it is important to further monitor saltwater crocodile population trends to ensure that the recent positive trend continues to support recovery of this top coastal and marine predator.

Saltwater crocodiles are the largest crocodile species in the world, and the largest living reptile in the world. However, crocodiles in the wild will usually go for crustaceans, frogs, birds, deer, etc. Even though the colossal crocodile has been known to survive the dinosaur period and species-ending asteroids, contrary to popular opinion, they are not immortal. Most crocodile species have a lifespan of approximately 40 years, however, large species like the saltwater and Nile crocodile have been known to live up to 80 — years.

Crocodiles are carnivores, which mean they eat only meat. In the wild, they feast on fish, birds, frogs and crustaceans.

At the zoo, they eat small animals that have already been killed for them, such as rats, fish or mice. They also eat live locusts. In the wild, crocodiles will clamp down on their prey with their massive jaws, crush it, and then they will swallow the prey whole. They do not have the capability to chew or break off small pieces of food like other animals. To help with digestion, crocodiles swallow small stones that grind up the food in their stomachs.

Thanks to their slow metabolisms, crocodiles can survive for months without food. During the Mesozoic Era , about million years ago, the Crocodilia order was one of the top animals on the food chain. Today, crocodiles are found in the tropical habitats of Africa, Asia, Australia and the Americas.

They normally live near lakes, rivers, wetlands and even some saltwater regions. One of the largest known populations of American crocodiles is found in the Dominican Republic's at a large saltwater lake called Lago Enriquillo, according to National Geographic.
