Animals

The mouth opening is located on the underside of the body between the legs. They move the food into the mouth with chelicerae—a pair of small appendages.

Their average lifespan in the wild, however, is still unknown.

40% of their body is made of fat.

Examples of such insects are the beetle Blaptica dubia and the fly Glossina palpalis (tse-tse).

While lizards have only one organ responsible for respiration-the lungs, salamanders rely on skin, gills or lungs (or, in some species, the combination of skin and lungs altogether).

Asian elephants can both push over a tree with their trunk, or pick up and shell a peanut.

It is not deadly, however, there are known cases of anaphylactic shock and cardiovascular collapse as a side effect of the sting.

They burrow in about October and leave them in March or April. Their activity is closely related to the ambient temperature.

In 2008 the number dropped to 100, and since 2013 no specimens have been found. Soon, axolotls may disappear from their natural environment entirely.
