Origin

The crocodile is a reptile order that together with the birds are the last descendants of the Arhozaurians, a category of dinosaurs.

Crocodiles have descended from 240 million years ago. Until now, 23 species of crocodiles are known.

All belong to the Crocodylidae family. The male crocodile can reach up to three meters in length while the female rarely exceeds two meters. There are some cases of giant crocodiles that can reach 5 or 6 meters long (salt water crocodile).

Both male and female live about 15 years. Crocodiles live in tropical regions of Africa and Australia while Aligators live only in South America and North America.

They do not live at all in Europe.

Crocodile’s Food

Crocodiles and related species are carnivores. The long jaw and look seems to have a sadistic jam, suggests aggressive and fierce behavior. Most people are horrified by crocodiles, though their feed depends on their size and the prey available around them.

At first, the crocodile pups feed on insects, tadpoles, snails, small fish, crayfish and shellfish. Because they grow very fast and can only catch small animals of prey, they eat very often.

As they grow up, they begin to capture bigger animals and simultaneously increase the duration between two meals. First they catch bigger fish and other reptiles, and then gradually hunt  mammals. Inhale any living thing in the way, be it monkey, buffalo, zebra, snake or even man. Many animals fall prey to crocodiles while quenching their thirst on the water’s edge. Crocodiles also consume stunts, not just live captured leeks.

As sharp as the teeth of these animals, they are still not suitable for the slaughter and devouring of the flesh of the leek. When a crocodile or alligator inhabits an animal that quenches thirst on the shore, it usually catches it and tries to pull it in the water to drown it.

Many times he has to put the prey in a hole in his mother’s throat until his skin is soaked and the meat begins to decompose, because only then can he squeeze it through big bites. Sometimes the crocodile or alligator begins to roll in the water with the prey in the mouth to pull out large pieces of meat from it.

He usually swallows the whole piece in his mouth. Often a prey serves as the food of many crocodiles that devour it on the spot. Crocodiles crush fish in little water: they just suddenly close their nose or teeth them with teeth.

They swallow the fish in their entirety with their heads, lest the gills or bones scratch the fragile tissue of the pharynx. Most crocodile species swallow various things, stones, pieces of wood, along with prey. They probably help fast digestion in the stomach.

Crocodile’s Features

The crocodile’s body is covered with bone plaques, and the circulatory system has kept some characters in common with birds. Animals today live on the shores of flowing waters or lakes in tropical or subtropical warm regions.

Some crocodile species can also be found in the salt water of the seas around the islands. These animals are good swimmers, when they hunt, they are hiding under water to the eyes and naves.

The shape of the body of today’s animals is adapted to the living environment in which they live, so the body is dorsventral, and ends with a narrow, muscular tail that helps to swim or as a rudder.

The mouth is wide with a strong conical dentition. Crocodiles have a body length depending on the species between 1,20 and 7 m long. Fossil crocodile excavations with a length of 12 m were found.

Animals grow throughout life, but as the age gets older, the growth process becomes slower, so older crocodiles grow only a few centimeters.

The crocodile’s skull is elongated, the eyes during evolution have come to be dorsally disposed, at the tip of the nose there are the large oval holes of the nostrils, which are so related to the pharynx that the animal and the full mouth can repel without any problems.

The crocodile crotch has different lengths depending on how it feeds, so the gavial that feeds fish has a long and thin snout.

Nostrils and the eyepieces of the ears are closing in the water. Vase helps him to find food. The mouth is wide, and there are conical, uneven, teeth in the jawbone of the jaws called the alveole.

The body is dorsos-ventral, covered with fleshy tiles, doubled by bone plates, unspoiled between them in the dorsal region. The tail is also compressed laterally. It has 5 free fingers at the front limbs and 4 fingers joined through the membrane to the hind limbs.

They serve in water and land. He goes out to dry to rest.

Crocodiles hunt using the ambush method. They stand still and wait for the prey to come very close to them. The prey can be represented by either fish or landfill animals that want to adapt. Crocodiles eat different species of birds or even smaller crocodiles.

Reproduction of the Crocodile

Four weeks after pairing, the female puts eggs, and after three months of waiting the chickens take the first steps. The nests of the eggs are made on the banks of the rivers, on the beaches, close to the water so that the small crocodiles are well protected from the attackers.

The woman uses all her energy to protect her babys. The female deposits between 30 and 60 eggs, then camouflages the nest. Spend little time there in order not to attract the attention of predators who may eat the eggs.

After 3 months the female checks the nest. The baby crocodile gets out of the eggs. They have between 85 and 115 grams. They are victims of raccoons or other predators who can eat them easily when they leave the eggs. In general, only 10% to 15% of them survived.

When it comes out of eggs, they have a food reserve for 4 months.

At the age of 8, I can already reach 2 meters in length. They feed on large fish, frogs, birds, snakes and even terrestrial animals that cross the river or feed on the edge of the river. The crocodile actually tears the prey by twisting and then swallows the entire unblemished pieces. If the river is crossed by a herd of antelope, it is hard for cats to catch something so they depend on the food they buy from the crows obtained by the dominant crocodiles. People are afraid of them, and poachers, unfortunately, are looking for them to hunt them.
