“…Nevertheless, investigations on phenomena in chemical ecology of marine organisms are increasing, and information is now available that sensory perception of chemical signals influences predation (e.g. Hay and Fenical 1988;Zimmer-Faust 1989), courtship and mating (e.g. Hardege and Bentley 1984), aggregation and school formation (e.g.…”

This study details the investigations of the effect of temperature and the presence of predators on the vertical distribution of the ctenophore Pleurobrachia pileus. Previous studies had suggested that P. pileus moves to the sediment when exposed to colder temperatures as an energy saving strategy. Although we did observe an effect of temperature on the movement of the ciliate combs, the effect of temperature on the average depth of animals in the water column was not significant, but a significant interaction was found between temperature and exposure time. In the presence of benthic predators or of water previously inhabited by these predators P. pileus changed its vertical distribution significantly, and moved away from the sediment, thus reducing the risk of being predated. We conclude that P. pileus can sense the presence of its predators, and changes its behaviour accordingly.

“…Blue crabs possess sensitive olfactory receptors, especially on the antennules, and respond to 215 concentrations of crushed clam extract as low as 10 M (Pearson and Olla, 1977). They use chemoreception for foraging in laboratory studies (Zimmer-Faust, 1989;Zimmer-Faust et al, 1995). In field experiments, they appear to detect additional prey patches within a radius of 10 to 15 m, displaying shorter patch visits (Clark, 1997) and better foraging success than when feeding on isolated patches (Clark, 1997;Hines, Terwin, and Thrush, unpublished data on file at SERC).…”

“…Crabs are rapid-moving predators that search for prey using chemical, tactile and visual stimuli (Land 1984, Zimmer-Faust 1989. The high vulnerability of small scallops to crab predators, due to the inefficiency of their escape response (valve closure), led Barbeau & Scheibling (1994a) to hypothesize that encounter rate is likely the major factor determining crab predation rates in nature.…”

ABSTRACT. We examined size-related changes in vulnerability of juvenile Iceland scallops Chlamys islandica to crab and asteroid predators using field experiments in the Mingan Islands, northern Gulf of St. Lawrence, eastern Canada. Vulnerability to both crabs and asteroids markedly decreased with scallop size, likely because of increases in the effectiveness of the scallop's antipredator defenses. Multiple-choice experiments showed that the crabs Hyas araneus and Cancer irroratus preyed mainly upon small scallops (10 to 30 mm). At our study site H. araneus was the most abundant decapod and was likely the major predator of scallops. Small Iceland scallops were generally found in crevices, byssally attached to the undersides of dead shells and rocks. Use of these refuges did not show die1 periodicity but decreased markedly with scallop size, attaining 0% for >60 mm scallops. Tethering experiments indicated that refuge use decreased vulnerability to both crabs and asteroids. However, the advantage of refuge use, in terms of reduced predation risk, varied with scallop size, being maximal for 15 to 30 mm scallops and only marginal for larger, less vulnerable scallops.
