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

Do insects have ears?

Yes. Many insects have ears, although they do not look much like ours.  The ears of many insects are not on their heads.  Crickets and katydids have their ears on their front legs.  Each ear looks like a little patch of cellophane.

The ears are actually membranes that work something like our eardrums.  Moths and grass hoppers catch sound on their abdomens.  Most insects can hear only the high-pitched sounds similar to those they make themselves.–Dick Rogers

Do fish have ears?

Fish

Yes, fish have ears and can hear.  But most fish hear very poorly.  You cannot see a fish’s ears because they are buried deep inside its head.  In addition, many kinds of fish also have tiny sense organs arranged in lines along the sides of their bodies which are called the lateral lines.

This organ feels vibrations in the water.  It lets the fish know what’s going on around it, even if it does not see or hear anything.  Through its lateral line organ, a fish can sense the vibrations of your footsteps along the banks of a stream and swim away. –Dick Rogers
