Special characteristics of animals that protect them from danger.special behaviour of animals that protect them from danger. The special characteristics and behaviour of animals help to protect them from danger.3.1 animals have specific characteristics and behaviour to protect themselvesThick and hard skinTo prevent their enemies from injuringHard shellSnails and tortoise retract their headAnd legs into the shell when the areAttacked by enemiesHard scalesPangolins and crocodiles have hard scales To protect their bodies from injuriesSpinesRaise the sharp spines when the enemies Advance towards themHorns Use their horn to attack enemies.Sharp clawsTo protect themselves and their Young from the enemies- lion ,cat,Bears, and eagle.Spray black inkDark surrounding helps the animal not to been seen by enemies e.g: octopus, squidPoisonous sting or fangsCan hurt and kill enemies-e.g..: scorpion, centipede snake , bee.CamouflageHas body colour or patterns that that are Similar to the surroundingPretend to deadTo trick their enemies e.g.: beetle
