Hello friends welcome to museum of Zoology Department, Shri Shivaji Science College, Nagpur. I am Lingula, a genus of brachiopods. I have a bivalve-like shell with a long, fleshy stalk. I inhabit shallow marine environments, often in sandy or muddy substrates. My body has remained relatively unchanged for millions of years. I am considered a living fossil. My presence indicates a stable and undisturbed marine environment. Thank you visit again.
