Dolphins are not fish, but warm-blooded animals.They live in groups, and speak to each other in their own language.In a way they are like other animals, such as bees and birds.But dolphins are very different from almost all land animals.Their brain is nearly the same size as our humans, and they live a long time-at least twenty or thirty years.

  Like some animals, dolphins use sound to help themselves find their way around.They also make the sound to talk to each other and to help them find food.We now know they do not use their ears to receive the sound, but the lower part of the mouth, called the jaw.

  Strangely, dolphins seem to like humans, and for thousands of years there have been stories about the dolphin and its friendship with people.

  There is a story about sailors in the 19th century.In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack.From 1871 to 1903, Jack met every boat in the area and showed it the way.Then in 1903, a passenger on a boat called The Penguin shot and wounded Jack.He recovered and for nine years more continued to guide all ships through the area-except for The Penguin.

  Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.

The Giraffe

  One of the tallest and most interesting animals is the giraffe.Male giraffes are usually about six meters tall.Half of the giraffe’s height comes from its neck, which is longer than its legs.

  A giraffe has big brown eyes which are protected by very thick lashes.Since it lives in parts of Africa which are usually dry with a great deal of dust, the lashes are an important source of protection.It can also cover its nose in order to protect it.It has brown spots on the skin and this color helps protect the giraffe.The giraffe also has two short horns on its head.

  Like the camel, the giraffe can go a long time without drinking water.One source of water is the leaves which the giraffe eats from trees.Since it is so tall, the giraffe can reach the leaves at the top of a tree.

  Giraffes usually live in small groups and often feed with other animals.A baby giraffe is two meters tall at birth.It can stand up by itself within a few minutes and can run well in about two days.

  Giraffes have two methods of self-protection.If something frightens an adult giraffe, it can run away at about fifty kilometers per hour or stay to fight with its strong legs.
