#video | How crocodiles run fast?

If necessary, the crocodile is quite unable to catch up and eat

If you watched the 1995 documentary or other documentaries about these carnivorous reptiles, you've probably seen how lazy and slow they look. However, it is not so, because while the nature of these dangerous creatures can literally ride the horse to catch its prey. Previously it was thought that walk-running is only capable Australian slender-snouted crocodiles (Crocodylus johnstoni), but recently, researchers from Britain's Royal Veterinary College found that this ability has many other amphibian predators.

About the opening of British researchers told the publication . Scientists led by evolutionary biomehanika John Hutchinson was installed on the territory of the Zoological Park in Florida and followed the way of moving reptilian predators. In particular, they were interested in 42 individuals of 15 species of crocodiles, which also had small alligators and caimans. During observations, researchers found that reptiles carnivores have a different manner of movement. However, some types of crocodiles if you need to run fast, jumping like a horse.

How crocodiles run?

While alligators and caimans mainly runner, moving alternately located on the diagonal pairs of legs, some crocodiles are able to run at a gallop. This ability was seen to Philippine crocodiles (Crocodylus mindorensis), tuporylye crocodiles (Osteolaemus tetraspis), and several other species. The researchers believe that the ability to run at a gallop and there are other species of crocodiles, the opportunity to study which they did not have. However, they have already received a message indicating that the same skill was seen in the Indian marsh crocodiles (Crocodylus palustris).

According to John Hutchinson, despite the different manners of running, the crocodiles and alligators develop equally greater speed. Regardless of body size, these mammals are capable of running at speeds up to 18 kilometers per hour. Only now like it or not, when running the crocodiles do a lot more steps than close relatives. According to researchers, the fast cadence allows young crocodiles faster to escape from larger predators, but alligators and caimans this ability can not boast.

Why are alligators not capable of running such a way, scientists do not yet know. There is an assumption that the crocodiles got a skill inherited from one of the ancient ancestors. Possible to run at a gallop were ancient predators called Rauisuchia, which were very similar to modern crocodiles and at the moment considered .

Also it could be that fast running with high cadence some species of crocodiles have been trained over time. This ability could be they need for survival, because in some regions of our planet on small reptiles hunt more dangerous predators and from them to the crocodiles, it remains only to quickly flee and hide from sight.
