Spiders eat insects, other spiders, or, sometimes, nectar.

The goliath bird-eater is generally considered to be the largest species of spider. It is a species of tarantula and its leg span can reach 11-12 inches (28-30 cm).

Spiders don't necessarily sleep, in the sense that we do but they slow down their circadian rhythm.

Most spiders live for at most two years. Tarantulas and other mygalomorph spiders can live up to 25 years in captivity.

Many female species die after producing the last egg sac.

Female spiders produce either one egg sac containing several to a thousand eggs or several egg sacs each with successively fewer eggs.

Each type of spider tends to be found in a habitat to which it has become specifically adapted.
