The main task of the legs is to walk and run. Animals can also use them for digging holes, protection, attack, and during mating games. 
But the structure of the limbs of some living creatures is so interesting that at first glance it is even difficult to imagine what other functions they perform.
Defying gravity 
Due to the tiny hairs and bristles on their paws, geckos calmly drive not only on horizontal, but also on vertical surfaces.
Guarantor of reliability 
The alpaca finger has a soft pad and a hard claw for easy movement over difficult terrain.
Strong but neat 
Nature gave rhinoceroses thin and even graceful ankles. At the same time, the pressure on the feet of these impressive creatures is enormous, so to reduce it, they have three unusually shaped toes on their feet.
Dangerous suitors 
The platypus is amazing in itself. Males also have poison-charged spurs on their paws. Which hero-lovers use with might and main during the mating season to get rid of rivals and capture the attention of the lady.
Laconic birds 
Ostriches have only two toes on their feet. But they are very good at running away, as well as catching up. They can also give very noticeable blows with such paws.
A very clawed miracle 
The armadillo is a miracle in itself. And also the owner of long and strong claws, with which he destroys termite mounds and digs cozy holes for rest.
Buzzing Annoyances 
Why does a fly hang upside down on the ceiling and not fall? Because it can. Or maybe thanks to the sticky pulvilla pads, which provide excellent adhesion.
Insidious bloodsuckers 
Mosquitoes are equipped with similar pads, which can hide and lie in wait for a victim for a long time in the most inconvenient places.
Slow metalheads 
The unusual deep-sea snail Crisomallon boasts a foot that resembles armor, which is necessary for protection against predators.
