“…An active escape response is usually evoked after recognition of a specific predator (Kohn 1961, Phillips 1976. For example, the North American whelk Buccinum undatum responds strongly to its main asteroid predators in laboratory trials, but not to asteroids that do not naturally attack it, suggesting that bivalves can discriminate between predatory and non-predatory asteroids (Thomas & Himmelman 1988). In our study, the native seastar Coscinasterias muricata elicited almost immediate escape responses by the scallops, indicating that they are aware of the potential predation threat.…”

“…Causality is a problem here, as whelks may be reacting to crabs or vice versa. However, the former interpretation is more likely because both crab species are natural predators of Buccinum undatum (Thomas & Himmelman 1988) and are known to prevent or delay entry of whelks into baited traps (Hancock 1974, Miller 1990. Whelks avoided crabs on many occasions at sites AN and IF.…”

“…Whelks (from hereon, the term whelk designates only B. undatum) are facultative scavengers (Nielsen 1975) which are reportedly attracted to bait from distances that rarely exceed 30 m (Himmelman 1988, McQuinn et al 1988. Natural predators of whelks include the crabs Hyas araneus (Linnaeus) and Cancer irroratus Say (Thomas & Himmelman 1988).…”

Aggregation of the gastropod Buccinum undatum Linnaeus around bait was studied at 2 subtidal sites, with different current regimes, in the northern Gulf of Saint Lawrence, Canada. Timelapse photography, SCUBA and current recordings were used to measure and interpret movement and behavior of whelks up to 25 m away from the bait. Objectives were to test the hypothesis of upstream movement to bait, and to determine relations between whelk arrival rate at the bait and currents and predators. In the absence of bait, 75.8 % of whelks were static or buried. In the presence of bait, whelks in a 20 to 60' downstream sector to a maximum distance of 20 m moved towards the bait. Whelks apparently oriented to the bait by chemotaxis Average crawling speed towards the bait varied from 7.3 to 15.1 cm min-' and was independent of current speed. More whelks arnved at bait per unit tlme when current direction changed gradually than when current was directlonally stable; this was due to exploitation of new grounds and to depletion of the downstream population respectively. A model and Indirect field evidence indicate that whelk arrival rate is depressed by sudden and marked changes in current direction, because whelks are unable to track the shi,ting odor plume. Arrival rate was positively correlated with current speed with time lags of up to 3 h, but tended to be negatively correlated with longer time lags. Arrival rate was negatively correlated with the numbel of predators (Cancer irroratus and Hyas araneus) at bait with time lags of up to 1 h, but positively correlated with numbers of H. araneus at bait with longer time lags. These correlations are explained by changes in the characteristics of the odor plume and by agonistic interactions.

“…In the marine environment, for example, such studies have revealed that gastropod populations exposed to high levels of shellcrushing predation often produce stronger and more ornamented shells that are more resistant to breakage (e.g. Kitching et al 1966, Hughes & Elner 1979, Currey & Hughes 1982, Vermeij 1982, Palmer 1985, Johannesson 1986, Thomas & Himmelman 1988, Boulding et al 1999, Trussell 2000b, whereas populations exposed to lower levels of like predation typically make thinner and less defended shells, presumably because these are less costly (Palmer 1981(Palmer , 1992). …”

The shell architecture of the intertidal snail Littorina obtusata (L.) is thought to have undergone an adaptive transition in response to invasion of the Gulf of Maine, NW Atlantic, by the European green crab Carcinus maenas (L.). In order to investigate the hypothesis that this morphological transition affects snail fitness, we conducted predation experiments with snail populations showing morphological differences that are hypothesized to have been caused by, and affect resilience to, green crab predation. Our results are consistent with the adaptive-transition hypothesis, but they reveal more varied predator foraging tactics and prey defensive attributes than previously considered. Crabs killed smaller and less heavily-armored snails by breaking their shell, but killed larger and more heavily-armored individuals using a fairly complex 'shell-entry' tactic, which we refer to as 'winkling'. The snail population which suffered lower mortality from green crab predation apparently obtained protection from crushing by having a thicker, more massive shell, and from winkling by having a smaller aperture. Our study provides evidence that the morphological transition undergone by L. obtusata following the green crab's invasion of the NW Atlantic is adaptive, and raises new questions regarding the phenotypic basis of this recent ecological interaction.
