The eyes of a bee

If you look on p8 of 'Would You Be a Bee?' you will see that a bee has 5 eyes. Here are some more facts about the eyes of a bee and some other animals:

• Bees and other insects have 2 compound eyes and 3 simple eyes. The compound eyes are huge eyes on the side of a bee's head that are made up of about 6900 hexagonal lenses.
• Although the bee has 5 eyes, it can not see very well. It can only see objects of about 1 metre away and it can't see the colour red at all.
• The compound eyes are very good for sensing movement.
• The simple eyes help the bee tell the difference between light and dark.
• Other insects such as cockroaches, butterflies and dragonflies also have compound eyes. Their eyes are so big that these insects can see all around them.
• Most spiders have eight eyes. These are simple eyes at the top of the spider's head. These allow the spider to see in all directions.
• The jumping spider has two eyes that are more developed than the others. These help the spider judge distances when jumping.
• A cat has poor coloured vision. Cats mainly see the world in black, grey and white.
• Cats can see much better in the dark than they can in the daylight.
  
• The animal with the biggest eyes in the world is the giant squid - its eyes are as big as a man's head!
