In water it can move at a speed of up to 30 km / h, although it often floats at a speed of 3-5 km / h. It prefers to hunt this predator early in the morning and late in the evening, at dusk.

A predator attacks either near the shore or on the shore. According to statistics, this reptile kills two people a year, but this is only official data. There is an opinion that some cases are not registered and in fact there are much more victims.

A combed crocodile can eat a person.

Reproduction and longevity

These reptiles breed in the rainy season. Saltwater crocodile belongs to oviparous animals. In the clutch there can be from 30 to 90 eggs, usually there are 50-60 of them. Nest equip nearby with water, on any elevation. The female collects branches, dirt, foliage in a heap and bury the masonry there. The diameter of the resulting hill is about 1.6-1.8 meters, it reaches a height of 50 cm. In this heap, a temperature of about 32 degrees Celsius is constantly maintained. Nest equip from year to year in the same place.

The eggs in the clutch lie from 80 to 98 days, then the young hatch from them. All of them are of the same sex, which depends on the temperature that was in the nest during the incubation period. If the temperature was 31.5 degrees, then males are born, if the temperature was a little more or less, then females are born.

Hatching cubs immediately give voice, hearing their squeak, the female rakes the hill, opens the nest and helps the offspring to get out of there. Then she, taking the little crocodiles in her teeth, carries them into the water. The female is next to the offspring while they get used to the aquatic environment. Young animals have a very high mortality rate; only about 5% of the brood survives until adulthood.

These reptiles can live up to a hundred years.

The remaining cubs become victims of monitor lizards, turtles, crocodiles and other predators. The first year and a half of life, the cubs live with the female, and then leave for their own territory. From the age of two, crocodiles gain complete independence. The lifespan of these reptiles is up to 65 years. Some experts believe that a crocodile can live 100 years.

Number

Since 1980, combed crocodiles have been on the verge of total annihilation. These animals were captured and killed for their skin, which is much appreciated. Predators were even listed in the Red Book. To date, legislation has limited the capture of crocodiles. There is a practice of growing them on special farms. In particular, they do this in India.

The largest population lives in Australia, about 120 thousand of these animals live there. To date, the number of combed crocodiles has a stable level and does not cause concern.
