Spiders have very small mouths. And just like spiders, the insects that are their prey have hard outer bodies. In order to eat their prey, spiders use their strong jaws to puncture the hard outer bodies of insects they have caught. They then throw up special juices from their stomachs into the insect's soft inner body. Within seconds, whatever these juices touch turns into liquid. The spider then sucks the inside of the insect dry and eventually all that is left is the hard insect outer body suit.

responsible for the deaths of many tiny aquatic organisms. Some of
the drugs have also been found to alter spawning patterns in
different types of marine species. 10 MAY 2000
