The jaw strength of a crocodile is 3 times stronger than a lion
Crocodiles have the most powerful bite ever measured for an animal now alive. For example, the saltwater crocodile, which is found near Australia, can bite almost three times as hard as a lion or tiger.
Large crocodiles can bite with a force of more than 5,000 pounds per square inch. That bite is stronger than a hyena or even a great white shark! In fact, their bite force may rival that of the mighty T-rex.
Paleobiologist Gregory M Erickson and his colleagues tested 23 living crocodile species through bite tests. Erickson and his colleagues physically measured the bites of some saltwater crocodiles up to 5.2 meters (17 feet) long, including Nile crocodiles, alligators, caimans, gharials and other crocodiles.
The result is that the saltwater crocodile has a jaw force of about 3,700 pounds per square inch (psi), or 16,460 newtons. Hyenas, lions and tigers, on the other hand, produce about 1,000 psi (4,450 newtons). In contrast, humans use only 150 to 200 psi (890 newtons) to cut a steak.
That's what makes crocodiles such successful predators. Any prey caught in their jaws is impossible to escape. However, crocodile jaws are also very sensitive to touch—more so than human fingertips.
How can a crocodile's jaws, which are as strong as steel, be so sensitive? Crocodile jaws are covered with thousands of sense organs. "Each nerve ending emerges from a hole in the skull," said researcher Duncan Leitch, quoted by SINDOnews from the jw.org page, Sunday.
This arrangement protects the nerve fibers in the jaw while providing greater sensitivity at some points. As a result, crocodiles can distinguish between food and dirt in their mouths. (Also read; This Modern Crocodile Fossil is 155 Million Years Old, Has 30 Sharp Teeth and Weighs 500 Kg )
Crocodiles can also carry their small children in their mouths without having to worry about accidentally killing them. So crocodile jaws are a surprising combination of strength and sensitivity.
The way crocodiles mate turns out to be unique!
How crocodiles mate and when do crocodiles mate really makes people curious. Because this cold-blooded animal is known as a loyal animal and a symbol of marriage in Jakarta's original culture.
When entering the mating season, in general, female crocodiles will become very active if they have entered a period of heat. Crocodile mating season takes place in the summer between July and August.
Quoted from the Fauna.id page, before the mating process, male crocodiles will enter the female's territory and control their territory. Once the area is determined, the male approaches the female by gently rubbing her head.
In addition, the male crocodile will rub his body on the female crocodile and will see the reaction from the female. If the female accepts the presence of the male, the female will make a certain recognizable sound.
During the mating process, the male crocodile will lie on the female's back and wrap her hind legs and tail underneath her, so that their genitals touch.
The male crocodile will fertilize the female's egg. Copulation or intercourse is carried out in water and will mate for several periods.
Female crocodiles are also known to be very selective towards their males. Certain sires are so jealous that it is impossible to allow another female to enter their territory.
The female Estuary Crocodile, before laying her eggs, prepares a place for nesting which is not far from the river bank. The bitch will collect leaves and twigs for nesting.
Next, the mother digs a hole and collects mud using her hind legs and tail. Once the nest is ready, eggs are laid in the nest to protect the eggs from predators. In one laying, the female will produce up to 100 eggs, depending on the type.
