Developing Vibrograms of Marine Gastropods: Gliding into Their Sensory Ecology and the Potential Effects of Noise
摘要
Vibrational noise generated by anthropogenic activities such as pile driving and seabed mining is increasingly recognized as a potential stressor for animals in marine environments. Aquatic gastropods, which fulfill key ecological roles and rely on mechanoreception for essential behaviors, may be particularly vulnerable to such disturbances. This paper reviews the sensory systems of aquatic gastropods, with emphasis on mechanoreceptors including statocysts and epithelial sensory cells which are likely involved in detecting substrate-borne vibrations. Methodological considerations for assessing gastropod sensitivity to vibration are outlined, including the importance of stimulus characterization, experimental exposure mapping, and the use of behavioral thresholds to produce vibrograms. The relevance of gastropod sensory systems to understanding the potential effects of vibrational noise is discussed, alongside findings from other mollusc taxa. Despite the presence of substrate-borne vibration in various habitats, there have been no studies to date that have directly investigated the effects on gastropod species. This highlights the need for targeted baseline studies to better understand vibrational sensitivity and inform effective environmental management strategies that account for substrate-borne noise.
