Synopsis Many prey organisms respond to the nonconsumptive effects of predators by altering their physiology, morphology, and behavior. These inducible defenses can create refuges for decreasing likelihood consumption predators. Some prey, as in marine mollusks, have been shown alter morphology response presence size-limited predation. To extend this work, we exposed pointed campeloma snails (Campeloma decisum) chemical cues from a natural predator, rusty crayfish (Faxonius rusticus), better understand how snail changes under threat The total force needed crush shells, shell length, aperture width, weight, along with these 3 body measurements, were recorded each individual used quantify morphological function risk. Snails had shells that required significantly more than controls (P = 0.023). Total length was greater crayfish-exposed control 0.012), treatment also showed change 0.007). Similarly, width 0.011). However, exhibited less 0.03). Finally, found weighed 0.008). Thus, results study show gastropods is altered predators, may be an antipredator tactic directly related predation
