Sea urchins eat algae, small fish, mussels, sponges, brittle stars, and crinoids. They stun them with their spines. Their mouth is located on the bottom of their body. They have almost invisible tube feet.Its very cool to see in the scientific research videos.

Why are sea urchines called porcupines of the sea?

Sea urchins are often referred to as the "porcupines of the sea" due to their spiny exterior, which resembles the quills of a porcupine.

Additionally, both creatures inhabit similar niches in their respective environments, with their spiny features providing both protection and a distinctive appearance.
