Does fish have Quills or Thorns Bones?

Fish do not have quills or thorns. They have bones, which are a type of hard, rigid tissue that makes up their skeleton.

Here's why:

* Quills are sharp, pointed structures found on animals like porcupines and hedgehogs for defense.

* Thorns are sharp, pointed projections found on plants for defense.

Fish are aquatic animals and don't need quills or thorns for defense. Their bones provide structure and support for their body, and they have other mechanisms like scales, camouflage, and speed for protection.
