15.They have no brains and no spines (脊椎).You can often see right through them.But they can cause painful,sometimes deadly stings (刺伤).Some can even glow in the dark!Scientists know them as medusas,but most people call them jellyfish.Jellyfish are not really fish.Jellyfish have stomachs and mouths,but no heads.They have nervous systems for sensing the world around them.They are made almost entirely of water,which is why you can look through them.Most jellyfish live in salt water,apart from a few types that live in fresh water.Jellyfish are found in oceans and seas all over the world.They live in warm,tropical seas and in ice waters near the North and South Poles.
Adult jellyfish are shaped like an open umbrella or a bell.A Jellyfish has tentacles (触须) at the edges of its body.At the center of a jellyfish's body,where it is widest,is the mouth.The ends of the tentacles have sting cells on them,which jellyfish use to catch their prey (猎物).Some jellyfish have powerful stings that can kill people.
Most jellyfish eat fish,tiny creatures and even other jellyfish.Once a jellyfish stings and catches its prey,it takes the prey to its mouth and swallows it.
Some jellyfish are very small,no longer than a marble (弹子).Others are quite large.The largest jellyfish can grow to about 7feet (about 2meters) across and weight hundreds of pounds!Jellyfish may be blue,orange,pink,yellow,purple,and other colors.
Some jellyfish can glow in the dark by making their own light.The light is made by a chemical reaction inside the jellyfish.Scientists believe jellyfish glow for several reasons.For example,they may glow to attract animals they prey on.
