Hello friends Welcome to zoology museum, Shri Shivaji Science College Nagpur "I am Echinus , a sea urchin with a spherical, spiny body. My spines are long and sharp, offering me protection from predators. I graze on algae, using my specialized mouthparts, known as Aristotle's lantern, to scrape surfaces. My body is covered in hard plates, forming a tough outer shell. I am often found in shallow, rocky environments along coastlines. I play a crucial role in controlling algal growth in marine ecosystems. My species has existed for millions of years, contributing to ocean biodiversity." Thank you visit again.
