to protect themselves from their enemies
It really depends on what sort of animal it is
because they want to live like any other animal...
When the predator goes to bite the animal it tastes the poison and leaves it alone.
they use there spikes to defend themselves so if an animal comes and touches it while it is in a ball it will get thorns on the other animal
They protect themselves by squirting blood from their eye sockets and on to the animal but only when they think the other animal is trying to kill or eat them!! P.S I have one myself and they don't do that to humans!!
well its the same reason why you do it, why do you protect your self so that you don't get hurt, or maybe even get killed so they make these kinds of precautions. or maybe the animal is trying to protect its young
They protect themselves by squirting ink.
