8 Animals that Use Spikes and Spines as Tools

In the animal kingdom spikes and spines are used as a defense, for attacks, to help with digging and some are even used as straws!

This article will let you know why animals have spikes and spines and how they use them.

8. From Pufferfish to Hedgehog

The pufferfish puffs up when threatened to scare off any attackers. It sucks in water in seconds, and pumps itself up into a balloon with countless spikes that stand on end. With just one look, the attacker knows: “Oh, this fish is too big for me!”

It does sometimes happen that the pufferfish is a little slow and only puffs up when it’s already in the mouth of its hungry attacker. The pufferfish might not be swallowed but it can’t get away either. The result: both fish die.

7. The Thorny Devil Has Straws

This iguana does its name proud. It lives in the deserts of Australia, where it feasts on tasty ants. To avoid being eaten itself (by birds), it has protective thorns made from horn all over its body.

It almost looks like an alien. No wonder that birds tend to stay away. The spines also have another practical purpose: When dew gathers on the spines in the night, it runs along the spines on the creature’s back directly into its mouth. Cheers!
