Sea Urchin

Hello friends welcome to museum of Zoology Department, Shri Shivaji Science College, Nagpur. I am a Sea Urchin, a spiny marine animal. My body is covered in sharp spines for protection. I have a hard, calcareous shell called a test. My mouth is located on the underside, with a structure called Aristotle's lantern. My spines can be venomous in some species. I move using tube feet located on my underside. I am found in a variety of marine environments, from shallow waters to deep seas. Thank you visit again.
