Spiders are part of the species "arachnids" indeed they are not insects. They have eight legs and lack wings or antennae just like scorpions, mites, ticks or uropyges.

Contrary to popular belief, the spider does not spend time waiting for a prey to get lost in its silk cloth, many of them are ruthless hunters, always on the lookout for prey potential. Although it is not the animal most appreciated by humans Arachnophobia (an irrational fear), it is a major player in the regulation of many insects.

They have a formidable weapon, their venom, which can be used to kill prey or deter predators. There are more than 200 species capable of causing serious consequences for humans; We must be reassured that the most dangerous are found in the tropics, besides the most widespread bites certainly cause significant pain, but without significant danger.

Spiders have a great ability to adapt to different natural environments, they are found from the 2 poles to the tropics, in the terrestrial space and the aquatic space; however, they have not yet conquered the territories of high mountains or salty waters.

This animal has the ability to produce silk using tiny articulated protuberances, which are visible on the ventral side at the end of the abdomen. The silk, in the liquid state in the glands, solidifies once in contact with the free air. These silk threads are surprisingly strong, in fact they have a greater resistance than steel.

They produce different types of silk that can be both sticky and slimy.

Spiders can be classified according to their life expectancy. The so-called seasonal spiders live from 6 to 8 months at the most, and after laying their eggs they die. Annual spiders can expect to live 1 to 2 years, they die once the eggs have hatched. Perennial spiders, such as tarantulas, have the longest life expectancy since they are several years old.

In order to grow, spiders must get rid of their exoskeleton, to do this they moult; they can do it up to 13 times before reaching adulthood. Some moult about once a year to adult age (the mygale).
