Spider Eyes

We've learned that a spider's body is split up into the cephalothorax and abdomen.
A spider's eyes are on the cephalothorax.

There are so many spiders out there it's hard to keep track of what they are.
Even looking close sometimes it's very hard to tell the difference between two types of spiders.

One of the best ways to figure out what type of spider you're looking at is to look at the size, shape and place where it's eyes are.
Most spiders have eight eyes, but there are a few types of spiders that have six, four or two eyes.

The Caponiidae spider is one of the few spiders that has only two eyes.

Some spiders have big front eyes, and smaller eyes next to them

And some spiders have two rows of eyes, one row right above the other.
