　　If it is too late to hide or run away, an animal must use other methods to survive an attack. One type of snake that lives in Texas has developed an interesting way to defend itself. If it is attacked, it first makes itself look bigger and pretends to be a dangerous snake. If that doesn't work, the snake uses another trick: it rolls over, opens its mouth and acts as if it were dead. The snake is such a good actor that it seems quite dead. If someone picks it up, it hangs like a rope and doesn't move. However, if you roll it back on its stomach, it will roll over on its back again in order to look dead.

　　Another way to survive an attack is to have useful body parts. The turtle has a thick shell that protects it from its enemies, and other animals have teeth, claws, and horns that they can use to defend themselves. There are also animals that can use their tails to fight off attackers. A long tail can be used to hit an attacker, and there is even an animal whose tail will break off so that it can run away if someone grabs it.
