Which Animals Use Spikes and Thorns Like Tools?
A Fish Becomes a 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.

Scales as Straws
This iguana lives up to its name. Its home are 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!
