The poisonous snakes Rating

The species composition of the snake is about three thousand. They live on all continents except Antarctica. The wet tropics, the dry and hot deserts, dense forests and seaside suitable climate and ecological system quite tolerable for certain species of snakes.

Surprised not only their way of moving without limbs, but the way of food: the food they swallow whole. Extraction it is necessary to immobilize – to stifle or paralyze the input of the poison. About 10% of all snakes in the process of evolution evolved the ability to produce poison.

Snakes poisonous substances injected into the victim’s body through the upper canines, having internal channels. Some types of “snake community” inexplicably acquired the ability to produce a very strong poison several thousand times exceeding that which would have been sufficient. For example – the most venomous snake in the world in one bite secretes a dose of poison, lethal to 12 thousand rabbits.

Research is successful quite often: for example, in South East Asia were found unique flying snakes. but in Indonesia – the new Gecko. And again found unknown fauna.

Long-term field and laboratory work by a group of zoologists led by Omar Torres-Carvajal (Museum of Zoology, Pontifical Catholic University of Ecuador) led to the discovery in the forests in northwestern Ecuador a new species remnevidnyh thick-headed serpent, which was named Imantodes chocoensis.

To allocate a new view that allowed features of the structure of the head. Later DNA analysis confirmed the hypothesis and allowed us to determine the closest relatives of snakes. They were members of the species that live in the Amazon basin on the other side of the Andes. “One possible explanation for the differences Imantodes chocoensis and its closest relative is that the uplift of the Andes have divided the original population into two parts, each of which has evolved into a separate species,” said Dr Torres-Carvajal.

Remnevidnyh thick-headed snakes live in Mexico and Argentina and are different from other snakes of the New World with a very thin body, disproportionately slender neck, big eyes, and a dumb head. Continue reading
