Predatory and peaceful fish

Carnivorous (lat. Carnivora — “flesh-eating”) is a detachment of the placental mammals ( Mammalia ), consisting of sub-units dog-like family ( Caniformia ) and maskoobraznym ( Feliformia ). 11 modern families of prey contain about 270 species in 110 genera and are distributed almost worldwide. The vast majority of the squad are classic carnivores, hunting mainly vertebrates. Predatory sometimes is also divided into two groups that are very different from each other in their mode of life: terrestrial Carnivora ( Fissipedia ) and pinnipeds ( Pinnipedia )

Carnivora scientific name in Latin means “flesh-eating” and consists of two roots — caro (born. p. carnis ) ‘meat’ and vorare “devour, swallow”.

Many predatory eat not only meat. Bear ( Ursidae ) are opportunistic omnivores. some species such as the giant Panda and does specialize in plant nutrition. The small pandas, badgers, olingo, kinkajou, raccoons-Poloskov and raccoon dogs vegetarian food also makes up a significant, if not the main part of their menu.
