What animal drills holes in clam shells?
The moon snail finds a clam by feeling with its foot beneath the sand. 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.
How do you drill a clam shell?

What makes the hole in clam shells?
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).
Which animal feeds on clams by drilling a hole through the clam’s shell with its rasping tongue?
Marine snails feed on clams by drilling a hole through the shell to reach the soft body inside. Using a rasping tongue and a cocktail of chemicals to drill through the wall of the shell takes several days, but under stress of competitive pressure, snails attack through the shell edge — a faster, but riskier access.
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.
Is drilling shells toxic?
BEWARE the dust if you drill shells. It’s likely quite toxic. Wear a respirator and gloves.
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.
How does an octopus drill a shell?
A modern octopus uses a sharp ribbon of teeth called a radula on its tongue to drill a hole into thick-shelled prey — useful for when the shell is too tough for the octopus to pop apart with its suckers.
Why are seashells purple?

What do you use to drill a hole in a clam?
A whelk or a conch would use their radula to drill into the clam and then slurp out its meal … Leaving behind a perfectly symmetrical hole. Moon snails and oyster drills are also well-known for using this technique to drill into clams for a feast.
What kind of mollusk uses a radula drill?
Radulas are found on every class of mollusk except for bivalves. A whelk or a conch would use their radula to drill into the clam and then slurp out its meal … Leaving behind a perfectly symmetrical hole. Moon snails and oyster drills are also well-known for using this technique to drill into clams for a feast.
What does a snail use to soften its shell?
If suffocation does not work, then the snails will secrete a calcium based acid onto the prey’s shell to soften it. Once the shell is softened, the snail will use its radula (toothed tongue) to bore a beveled hole into the prey’s shell.
What kind of tongue does a conch have?
A radula is the sharp, drill-like tongue of some mollusks (e.g., whelk or conch). Radulas are found on every class of mollusk except for bivalves.
