Gastropods - Univalves

Some interesting things about Gastropods by Gerry Gastropoda:
  • All cone shells possess a poisonous dart (a modified radula) with which they harpoon, inject venom and thus kill their prey. Some cone shell possess venom is so toxic that if stung, it can severely harm or even be fatal to man.
  • When we hold a large seashell up to our ear, we can hear the sound of the seashore waves because the shell echoes and jumbles all the sounds around us!
  • The largest snail (univalve) known attained a length of 78 cm (two and one half feet) with a girth of nearly forty inches. This trumpet conch, Syrinx aruanus (Linneus, 1758), weighed in at nearly forty pounds.
