What are some examples of active & passive defenses evolved by animals?

Question

I can't think of any...

Answer 1

Active defense:  Fleeing, stinging and venom or poison

Passive defense: Camouflage, mimicry, and aposomatic coloring

Answer 2

Active Defenses:

1) the ferociousness of a badger

2) the "puffing up" of a monkey when it gets angry

3) snarling and roaring done by wolves and other predators

4) the spiked tail of a stegosaurus

5) the spray of a skunk

6) the acid of the bombardier beetle

7) the ink squirting organs of a cuttlefish or squid

Passive Defense

1) horns on a chameleon

2) the disgusting taste of stink beetles

3) the pattern on a caterpillar that makes it look like a snake

An active defense is a defense mechanism employed by the animal. It "does" the defending--it attacks or roars or stings... The passive defense is a property of an animal that prevents an attack, rather than reacts to an attack. A thorny animal (a porcupine) doesn't charge it's attacker--the attacker knows (or learns quickly) not to attack. It's defense is passive. But as you come close to a bee hive, the bees rush out and sting you! Their stinger didn't protect them until they attacked--hence active defenses! Hope this helps!

Answer 3

Active-skunk spray of stink.
