How many eyes does a spider have?

Most spiders have eight eyes.  There are also six-eyed, four-eyed and two-eyed spiders.  Some species of spiders that live in cave and other dark places have no eyes at all.  A spider’s eyes are on the top and near the front of its head.

Even though a spider has so many eyes, it can only see things a few inches from its face.  To make up for their nearsightedness, spiders have a very strong sense of touch and taste.  Special hairs on the spider’s body contain nerves.  These nerves act as “ears, nose and tongue” to sense danger, as well as to locate food.–Dick Rogers

Why do bats hang upside down?

Bat

As a rule, bats sleep during the day and fly about at night.

To sleep, they hang themselves upside down in a cave or hollow trees, with their wings draped around their bodies like cloaks.

Bats are clumsy on the ground because their feet and legs are not suited for walking.

When a bat rests, the easiest thing for it to do is to hang on, head down.

The bat’s toes bend inward and end in book like claws—just what the bat needs to hang securely from almost any rough surface, such as the roof of a cave.

The mother bat carries her young with her.  The babies hang on tightly with their claws and teeth as the mother flies about hunting for food.

When the bat babies grow too big to carry, the mother hangs them up by their feet on the perch when she goes out. – Dick Rogers
