Dog Whelk Nassarius Family Nassaridae These carnivorous snails are common on the surfaces of sandy/muddy shores. Like moon snails, they also drill into shellfish. Live whelks are easily recognised by their long trunk-like proboscis which extends vertically above the substrate. In other countries, they are serious pests of oyster beds, where they are known as "oyster drills". (Shell 1-2 cm).
