How spiders eat insects

Spiders have fangs that inject venom into their prey to paralyse them. Because the spider's gut cannot handle solid food, it uses enzymes to liquefy the insect's innards before ingesting them.

Spider facts

Some spider species do not spin webs. They wander in search of prey, and attack aggressively. Spiders have six to eight eyes, but most species have poor vision.
