Arachinids

From Wikipedia:
Do you know that spiders are not insects?

Spiders belong to Arachnids which are a class of joint-legged invertebrate animals.
Arachnids have four pairs of legs and they may be easily distinguished from insects since the latter have 3 pairs of legs.

Arachnids are further distinguished by the fact they have no antennae and no wings. They are mostly carnivores, feeding on the pre-digested bodies of insects and other small animals.

Arachnids usually lay eggs, which hatch into immatures that resemble adults.
