Water loss by evaporation has to be tolerated (by means of the operculum which holds water in and prevents its escape as vapour), or avoided (by moving into water or a shaded area). Larger dog whelks tend to handle larger prey than small dog whelks.
In experiments it has been shown that 50% of dog whelks die at 40 °C, and it can be assumed that at temperatures lower than this a smaller proportion will be killed off.
The external shell colour is usually a whitish grey, but can be a wide variety of orange, yellow, brown, black, or banded with any combination of these colours.

Bryan & Gibbs (1983) noted that. Journal of Experimental Marine Biology and Ecology, 32, 75-94. Short squat shells offer less resistance to water flow and wave action and exhibit a larger aperture and larger foot and hence increased pedal surface area, which increases their adhesion the substratum (Cooke, 1895; Kitching & Ebling, 1967; Crothers, 1985; Etter, 1988). Some have kept groups of dog whelks in cages in rivers and estuaries for several months while others have monitored natural populations on the shore for many years.
However, a double-checked trace of bromine, indicating the presence of whelk-dye, has been found on one page of an Anglo-Saxon book known as the Barberini Gospels.

Occurrence dataset: http://www.ericnortheast.org.uk/home.html accessed via NBNAtlas.org on 2018-09-38, Fenwick, 2018. The white form predominates in the UK, but coloured shells predominate in the southern limits of its range (Portugal and Northern Spain) and in northern populations in Iceland (Crothers, 1985).
It lives in the middle shore.

Sandison (1968); (reported unpublished in Lewis, 1964) noted that heat coma occurred in. He also demonstrated that dog whelks from sheltered shores would develop a larger foot when transplanted to wave exposed shores. The chewy flesh is quite juicy and salty. Kirby, R.R., Berry, R.J. & Powers, D.A., 1997.
Dog Whelks lay their eggs in small yellowish capsules which can be spotted under rocky overhangs on the lower shore. Oecologia. Fish, J.D. The taxonomy of Nucella lapillus was reviewed by Crothers (1985) and Kool (1993).  At low vertical heights it is biotic factors, such as predation from crabs and intraspecific competition, which cause problems.
The shell is broadly conical, bearing spiral ridges and consisting of a short pointed spire, dominated by the last whorl.
