The freshwater snail Pomacea canaliculata shows alarm responses to chemical cues released from injured conspecifics, but its behavioural responses in the field are unknown. We investigated effects of habitat (canals or paddy fields), vegetation, and body size on alarm responses in the field. Snails responded to crushed conspecifics within 4 min by burying themselves, but the proportions of self-buried snails were generally lower (0–28% depending on experiments) than those reported in the… CONTINUE READING
