The Protée Proteus is a anguinus salamander amphibian. This animal , close to the triton or Salamande is rare, it has a way of cave life and is found in the western Alps (Slovenia , Albania, Kosovo , Bosnia and Herzegovin .) It is found under various names such as Proteus anguillard (which is shaped like an eel ), white salamander salamander or caves. There is even the popular name of " human fish " because of his skin that has a similar texture Rights .
The Proteus measure 20 to 40 centimeters long. It reaches sexual maturity at 15 years and its lifetime is estimated at 80 years according to the CNRS. This animal has gills and lungs ( it could hypothetically be rehabilitated mode earthly life This is a water cave and body . That is to say , living in a dark environment, where light is absent, typically in a cave or cave the cave species have many changes . partial or total blindness, skin depigmentation , slow metabolism that allows them to have a greater life expectancy .
He developed other sensory organs to move and hunt , bodies that have developed to compensate for the vision :
sensitive receptors : the skin is sensitive to light and developing a pigment called melanopsin which darkens the skin ;
chemical receptors : the smell perceives lower concentrations of organic compounds in water;
mechanical receptors : the epithelium of the inner ear captures sound waves and vibrations in the ground and locates their origin;
and electrical loads : it seems to be able to feel tiny electrical changes as the Earth's magnetic field to orient themselves.
It moves by undulating movements a bit like an eel and live, sleep and eat only in water. Outside the breeding season, the proteas can gather in large numbers in crevices or under stones. The power of this protected animal will be based primarily on bloodworms or tubifex live .
Because of its confinement in some underground caves , where special and difficult conditions prevail, the Proteus is particularly sensitive to changes in its environment. Indeed, the water present in the network of mainly limestone and porous rocks are quickly contaminated if surface pollution . The water flow is not filtered by a sandy layer , they quickly reach the lower levels and contaminating organisms that live there . The animal is also a victim of collectors ...
