What animal makes holes in shells?
Drilling predators such as snails, slugs, octopuses and beetles penetrate their prey's protective skeleton and eat the soft flesh inside, leaving behind a telltale hole in the shell. Trillions of these drill holes exist in the fossil record, providing valuable information about predation over millions of years.
What drills holes in snail shells?
Moon snails, common predators, use a combination of tiny teeth known as radula and acids to penetrate their prey's shell.
Can snails drill holes in clam shells?
The moon snail bores the small hole in the clamshell by using its radula. The radula is a tongue with teeth that is located in the head of the snail. ... Once it finds a suitable clam, the carnivorous snail uses that foot to hold the clam while its radula or spiny tongue starts to drill a small hole into the clam shell.

Do starfish make holes in shells?
While starfishes do feed on mollusks, they do not drill holes in the shell. They force the shell open with their strong, muscular arms.
Does an octopus have a drill?
Drilling of the hole is done by the radula. Since the octopus will drill and secrete into empty shells with obstructions in the apertures, metabolites from a live mollusc are unnecessary. ... The conditions under which the octopus drills or pulls out the body of the mollusc are incompletely understood.
What is the black stuff on shells?
Shells stained brown or orange got that way from iron oxide forming along the microscopic cavities of dead mollusks. Up to 30 percent of shells on any New Jersey beach will be brown. Black-stained shells have been buried in the mud for hundreds, if not thousands, of years.
Why is there a hole in a seashell?
Moon Snails, also called Shark-eye Snails, are predators, and they eat Arks, Coquinas, Surf Clams and other bivalves that live buried in the sand. ... With its radula, the Moon Snail drills a perfectly round, small hole through the bivalve's shell (and that is the hole you see).
What is that hole at the bottom of octopus?
The octopus also has a funnel, sometimes called a siphon, which is a tubular opening that serves as a pathway for water. You'll find out the purpose for this funnel later in the article. In place of the protective shell found in many other mollusks, the octopus brandishes a startling array of defense mechanisms.
