Avoidance of feeding opportunities by the whelk Buccinanops globulosum in the presence of damaged conspecifics
Feeding decisions under predation risk can be a key in the life of scavenger organisms, and tuned recognition of predation alarm cues and flexibility in the response are fundamental. The effect of injured conspecifics on the response behavior of the whelk Buccinanops globulosum to feeding opportunit...
