Yellow anaconda

(Eunectes notaeus)

The yellow anacondas, which can live to be up to 4 metres long, have their homes from southern Brazil to northern Argentina. Perfectly adapted to life in the water, they can see and breathe with their head almost entirely submerged due to the position of their eyes and nostrils. The yellow anaconda belongs to the family of boas and is a non-poisonous boa constrictor, just like its neighbour in Aquarium Berlin, the dark tiger python (Python molurus bivittatus).

What you should know about snakes
To date, around 2,700 snake species have been discovered, with this number rising. Around 400 of them can be considered as poisonous snakes, which you can classify into sea snakes, elapidae (e.g. cobras and mambas), vipers and pit vipers. Non-poisonous snakes are assigned into colubridae, boa constrictors (pythons, boas), acrochordidae and xenopeltidae, uropeltidae, typhlopidae and leptotyphlopidae, as well as aniliidae.

Yellow anacondas like it wet
The habitat of the excellent swimmers and divers includes light areas in moist forests and vegetation-rich bank areas of different bodies of water. Yellow anacondas will find a well-stocked selection of nutrition here, ranging from fish, amphibians, reptiles, birds and small mammals, on which they suddenly pounce from their waiting position, entwining themselves around the prey of choice and choking them to death.

Dark tiger python

Up to six metres in length and more than 90 kilos in weight, the dark tiger python is one of the largest snakes in the world. The snake, which is mostly active during dusk and in the night, prefers to live on the forest floors in large parts of tropical Asia. The dark tiger python prefers to stick to prey of its own size, from vertebrates up to smaller deer to an extent.

Is it true, that ...?
... Snakes have a sixth sense? Correct. What the pit vipers have as a pit organ between the eye and mouth, the boas and pythons have as the labial organ around the mouth. Both sensory organs are used to detect infrared rays. Snakes use the three-dimensional thermal images of their surroundings to hunt even in complete darkness.
