All about Spiders
Spiders are arachnids, not insects. They have eight legs and two main body parts, the cephalothorax and the abdomen. Most spiders have eight eyes, though many species have fewer, and they have no antennae.
Many spiders spin silk webs to catch insects, and some hunt without webs. Spider silk is incredibly strong and is produced in organs called spinnerets. Most spiders have venom to subdue prey, but very few are dangerous to people.
