Background information and definitions
Some subtidal benthic invertebrate species rely on sound to communicate, feed, navigate, detect predators, and reproduce. Underwater sonar sounds, for instance from naval ships, may be perceived by marine animals as a threat and disturb their anti-predator responses (Abate 2010; Harris et al. 2018). While the threats associated with sonar are so far mainly linked with marine mammals, in contrast little to no research has been undertaken on marine subtidal benthic invertebrates. However, this does not mean the use of sonar does not represent a potential threat to them, particularly as they can be negatively affected by other underwater anthropogenic noise (de Soto 2016; Pine et al. 2012). Limiting, ceasing or prohibiting the use of sonar underwater could prevent potential unforeseen responses from subtidal benthic invertebrates.
