What are dermal pressure receptors?

Dermal pressure receptors are dotted sensory pits found on the grades of animals in the order of Crocodilia, which include alligators, caiman and crocodiles. Animals in the Alligatorinae family have only pits in the head area, especially along the jaw, eyes, nose and upper floor. Animals in families Crocodylidae and Gavialinae will let them distribute them throughout their bodies.

Before they were given their current name, these sensory receptors were called the integer sensory organs (ISOS) due to their position in the integrated or outer layer of the skin. Along the jaw line resemble stubbles of black beards and can be up to three or four receptors at the outer edges of one scale. In other areas of the body, such as a crocodile abdomen, they are often white and can only exist on a scale.

reception of dermal pressure is not well understood, but it is assumed that their function withE differs depending on where they are on the body of the animal. Those on the head are very sensitive to the least pressure changes from the surrounding water. For example, when the fish floats in close proximity, disruption creates small waves that interfere with the receptors. The feeling draws attention to the crocodile or alligator not only of the presence, but also the precise placement of prey, even in murky water, where the vision is bad. On the surface, when they rest miserable with their eyes and exposed nostrils, the animal could immediately throw away and capture underwater prey, which was otherwise completely undetectable.

Alligators are mainly found in fresh water, while crocodiles live in bracket or salty water, resulting in some scientists to the theoretics that dermal pressure receptors covering the crocodile body can be involved in chemical reception or detection, but there is no evidence. Popular in the 20th of the 20th century, which led to animal hunting almost to extinction. VzThe alligators are recovered and the regulated trade in the Kots is again legal. However, crocodiles remain on the list of endangered species. If you buy shoes, belts or other objects advertised as alligatory leather, there should be no signs of these receptors, because the skin comes from the abdomen where this animal is not found. If they are present on some or all stages, the item is not made of alligator leather.

alligators occur mainly in fresh water, while crocodiles live in bracket or salty water, leading some scientists to the theoria that dermal pressure receptors covering the crocodile body could be involved in chemical reception or saltiness, but there are no evidence. He led to animal hunting almost to extinction. Due to efforts to conserve nature are aligators recovered and regulated trade in the skin is OPět legal. However, crocodiles remain on the list of endangered species. If you buy shoes, belts or other objects advertised as alligatory leather, there should be no signs of these receptors, because the skin comes from the abdomen where they are not on Tje's animal. If they are present on some or all stages, the item is not made of alligator leather.
