Snakes (in Latin Serpentes ) belong to the suborder of reptiles squamous. Their habitat is quite extensive: they live practically on all continents (except Antarctica and a number of large islands such as Ireland, Greenland, New Zealand, Malta, some islands of Oceania), in all climatic zones and ecological conditions (forests, steppes, deserts , Foothills, mountains). But still they prefer to settle in places with a hotter climate. Usually, snakes lead a terrestrial way of life, but some of them can live in water, on trees or underground.
By their nature, snakes are predators. The basis of their diet consists of a variety of species of animals, both vertebrates and invertebrates. However, there are snakes that specialize in eating a certain type of prey (the so-called stenophagus). Unlike poisonous, killing their prey with the help of poison, non-poisonous snakes can swallow it alive or pre-strangled. In this case, all the snakes absorb their prey entirely due to the specific structure of the lower jaw, consisting of the right and left halves, making them alternating movements and, as it were, pulling themselves into prey.
