Euspira lewisii

This marine snail can live for several years. They have an impressive feeding strategy, of digging into the sediment, to eat through the shell of another mollusc. The ability, to drill a hole through a tough clam shell, is accomplished with the help of a carbonic anhydrase secretion, softening the shell before a radula with 7 fine teeth drills into the prey shell. It will take it about 2 days to fully consume a clam. Males are smaller than females who can live up to 14 years old. Their strange egg casings can be seen, after late spring to early summer, and look like a ringed collar made of fine sand.
