The animal itself is white or cream coloured but rarely seen. The Dog Whelk (Nucella lapillus), can use its modified mouth to bore into molluscs. It can squirt a paralyzing chemical and digestive enzymes to help break the mollusc down. The resulting 'soup' is then sucked out with a siphon. The dog whelk secretes digestive enzymes into the body of the prey and then ingests the resultant tissue 'soup' (Crothers, 1985). The 'gape' attack method is energetically more effective (Fretter & Graham, 1994) and is more likely to be used by dog whelks with experience of handling the prey than inexperienced dog whelks and results in a lower prey handling time than boring (Rovero et al. , 1999).
