Neptunea antiqua, common name the red whelk, is a species of Northeast Atlantic sea snail, a marine gastropod mollusk in the family Buccinidae, the true whelks.[1]
Description
N. antiqua resembles Buccinum undatum (common whelk). It can grow to a length of 20 cm (7.9 in),[2] although most specimens only reach half that size.[3] It is the largest marine snail in parts of its range.[2]
Distribution
N. antiqua is found in the Northeast Atlantic along cold-temperate European coasts, ranging from the low water mark[4] to a depth of 1,200 m (3,900 ft).[3]

Feeding
N. antiqua is primarily a scavenger, although it has been recorded attacking and eating some living polychaete species.[4] Unlike several of its more predatory relatives, experiments have shown that even hungry N. antiqua are not attracted to living undamaged mussels.[4]
Food poisoning

N. antiqua contains tetramethylammonium salts (most likely the chloride) in its tissues, and has been the source of non-lethal human poisoning. [5]
