There are over 32,000 types of spiders living on Earth. They live in
almost every area from the hottest tropics to the cold continent of Antarctica.
Spiders are easily identified by their 8 legs and their ability to spin
Spiders eat insects that they catch in their web. They have fangs to
bite the insect. Many spiders also have poisonous glands to help kill
the insects, and some are even poisonous to humans.
Spiders have the ability to produce silk from an organ in their abdomen
called the spinneret. The spider's web has many purposes in addition to
being a place to live.
Spiders use their web to trap insects for food. Once an insect is caught,
they may also use their web to tie up their victim.
Spiders also lay a line of silk as they move around. They anchor the
line to a surface, and use the line just like a mountain climber uses
their safety rope.
