How does the dog whelk get inside the shells of snails?

The dog whelk, a predatory sea snail, uses a specialized feeding technique to access the soft tissue of its prey, typically other snails. It drills a hole into the shell of its target using a rasping organ called a radula, which functions like a tongue with tiny teeth. Once the hole is created, the dog whelk can then consume the snail's insides. This method allows it to effectively prey on snails despite their hard shells.
