It turns out that a large number of marine invertebrates hear and suffer from noise

New research confirms that low-frequency noise can be detected by lobsters, which can negatively affect them and other invertebrates.

In a new study, the authors found that the outer cuticular hairs that cover most of the lobster’s bodies are likely responsible for recording vibrations in sound. If so, then a large number of marine invertebrates nominally have hearing.

This is the first study to confirm that the American lobster has hearing: the authors of the work proved this using the so-called auditory evoked potential (AEP) methods. Such methods use electrodes located near the animal’s brain to detect the response of neurons to sounds.

As a result of the work, the authors raised concerns about the potential impact of anthropogenic noise on lobsters, as anthropogenic noise falls within the frequency range of lobsters, approximately 100-200 Hz.

This study provides preliminary insights into how man-made noise affects lobster behavior. This is to determine the real impact of the noise and try to reduce it as much as possible.
