Existence of venomous snakes and insects for anybody not a secret is known to Paleontologists for a long time. Also existence in waters of the World Ocean of poisonous fishes is not a secret. Relatively recently scientists told the truth about poisonous mammals. Practically all from them died out in prehistoric times, some evolved and still adjoin to us on Earth.

Poisonous Mammal of Lori

The fact that the majority of the mammals inhabiting the planet at the time of dinosaurs were poisonous is known to paleontologists for a long time. It in a new way lit all theory of world evolution.

Partially reconstructed fossilized remains of a skull of a pretty small animal obviously showed existence in the lower canines of an animal of the special grooves serving for injection of poison in a body of the victim at a sting.

This small animal was called Bisonalveus brownie and lived in the territory of North America more than 60 million years ago. Such examples at paleontologists a set.

Dangerous animals of the present

Presently on the planet remained only several animal types belonging to accidental, "side" evolutionary branches. They differ in existence of poisonous glands.

treat them :

  • Duck-bills.
  • Fat lories.
  • Shchelezuba (Haitian and Cuban).
  • American, ordinary and southern korotkokhvosty common shrews.
  • Canary belozubka.
  • Shaggy hamster.

Practically all these animals are endemics (that is live only in one region of the planet). Poisonous glands with them it is placed differently. Below more detailed description of each species of an animal follows.

Duck-bills and lory

Poisonous Mammal Duck-bill

At little duck-bills irrespective of sex on back extremities rudiments of horn spurs are placed. At one-year-old females they vanish, and at males and grow in this age further, reaching over time (at the time of full puberty) length of 1.2 — 1.5 cm

In the period of a marriage season in the special gland of a duck-bill which is placed on a hip specific poisonous cocktail is developed. By means of a channel poisonous gland contacts a horn spur. Males use these spurs first of all as weapon during marriage duels.

But also the duck-bill can elementary use this spur for murder of a dog of a dingo or any other medium-sized animal. To the person does not threaten to die of "prick" of a duck-bill, however, on his place very unpleasant painful hypostasis extending to all pricked extremity is formed. This hypostasis causes very strong pain (giperalgeziya) proceeding in certain cases up to several months.

Lovely small animals with huge eyes touchingly look on pictures. But here not everyone knows that the animals seeming, at first sight, lovely and defenseless are poisonous. Poisonous glands are located on front pads of an animal. By means of poison mother lory protects the kids (greasing them with a poisonous secret) from attack of predators when she leaves on search of food. Further animals use it for self-defense.

Is interesting also the fact that poison of fat lories is dangerous also to the person, especially in case of his hit on mucous membranes. All the known pose of these small animals with the front pads raised up. But not all know that it is a protective pose of a lory during which he attacks the rival.

of Shchelezuby

Earlier, in relic times (from an oligocene about one Holocene), these land insectivorous mammals lived practically in all territory of North America. Today their small populations remained only on the islands of Cuba and Haiti.

Poisonous Mammal Shchelezub

According to scientists, shrews and the Afro-Madagascar tenrek are considered as their immediate family. Even shchelezuba resemble shrews superficially. This quite large insectivorous small animals. Distinguish shchelezub :

  • Haitian — lives in remote forests of Haiti;
  • Cuban — there lives in thickets and the woods the island of Cuba.

Judging by remains, still the little in Cuba and Haiti lived earlier two more species of these small animals. Most likely, disappearance of their populations was directly is connected with invasion on islands of the European conquerors.

A channel of poisonous gland of a shchelezub to be about the basis of the second cutter of the lower jaw. Interesting feature of poison of shchelezub is that they have no immunity against own poison. For this reason a huge number of these animals perishes from it during collisions with relatives.

Besides other representatives of a shchelezuba of a type, protecting the territory, attack other animals, and people. To the person does not threaten to die of poison of a shchelezub, however the sting painful and causes very severe poisoning of an organism.

of the Common shrew

Poisonous Mammal Common Shrew

Rather strong poison of korotkokhvosty common shrews allows to cope without any problems with the opponents considerably exceeding them by the sizes. These poisonous shrews are developed toxins in submaxillary gland and gets to a wound of the victim at a sting.

At a sting poison affects first of all nervous system of the opponent . By the size these animals rather small (length of a common shrew does not exceed 10 cm, and body weight no more than 30 grams).

External differences between three subspecies of korotkokhvosty common shrews insignificant, and the mechanism of effect of poison is identical.

Canary belozubka

Poisonous Mammal Canary Belozubka

According to zoogeneticists, the Canary belozubk lived on the planet more than 5 million years ago. This endemic animal of the Canary Islands and the only land predator on Canary Islands, with an area of 5,000 km ².

There live belozubk on fruitless lava fields and is well adapted to a heat and dryness of plains. Sometimes Canan shrew it is possible to meet in rocky ravines, on the abandoned fields and in gardens of locals.

the poison these small animals use

to paralyze the production considerably exceeding them by the sizes, for example, of the Atlantic lizards.

Shaggy hamster

There live these unusual hamsters in mountains of East Africa, occasionally they can be met on plains. Wood life made them quick and dexterous. Are active at night, hide in holes and crevices in the afternoon. Eat vegetable food. For protection against predators use very unusual method.

Poisonous Mammal Shaggy Hamster

Barking a local tree (akokanter of the Abyssinian), they chew it and cover with the received chewing gum wool on sides. The hairs impregnated with poison, getting to a mouth to the forward, are capable to provoke cardiac arrest . Here such unusual animals adjoin to us on the amazing planet Earth.
