“…Snapping shrimps (among the Alpheidae family) produce among the loudest sounds in marine coastal environments and are known to dominate the soundscapes of coastal environments (Johnson et al 1947, Au & Banks 1998, Versluis et al 2000, Chitre et al 2012. However, the benthic invertebrate biophony goes beyond the contribution of snapping shrimps, since sea urchins (Radford et al 2008), crustaceans (Popper et al 2001, Coquereau et al 2016b, bivalves (Di Iorio et al 2012) and benthic populations in general (Coquereau et al 2016a) are also known to produce audible and distinct acoustic signals (namely broadband transient signals) while feeding, moving, etc. Altogether, these sounds, in this study referred to as benthic invertebrates sounds (BIS), contribute to benthic invertebrate biophony (BIB).…”

Coastal soundscapes are dominated by broadband transient sounds primarily emitted by benthic invertebrates. These sounds are characterized by a very large dynamic of amplitude. The loudest ones propagate further and interfere with the detectability of benthic sounds by invading other more distant habitats. Acoustic diversity assessment is therefore biased when applying acoustic indices related to the signal's power. Here, we propose new acoustic indices (IDSS: indices of the diversity of spectral shape) capable of extracting the diversity of the benthic invertebrate biophony (BIB) despite interference from loud and abundant sounds. A passive acoustic ecological survey was conducted in a shallow Mediterranean bay with a small-scale mosaic of biocenosis. The sound pressure level and spectrum of the BIB revealed that the rocky fringe had the most powerful biophony, propagating up to 3680 m, thus 'invading' other habitats. However, these power-based indices failed to depict BIB diversity. The IDSS allowed us to discriminate BIB diversity despite the interfering rocky fringe biophony, including low-power sounds not depicted by traditional power-based methods. Four main categories of benthic invertebrates sounds (BIS) spectra were found. Two categories (high-power, peak frequencies ~3 to 4 kHz) were mainly linked to the rocky fringe. Their contribution to the diversity (56%) decreased with increasing distance to the fringe, where low-power BIS (peak frequencies above 15 kHz) predominantly contributed to the BIB (42%) and may be specific to coralligenous reefs. The IDSS enables a better characterization and quantification of BIB diversity and soundscape structure with a fine spatial resolution (~200 m).

“…Comparatively, aquatic invertebrate sound production is less understood, but acoustic signals have been reported during courtship and mating (Salmon, 1967;Popper et al, 2001), defense (Meyer-Rochow and Penrose, 1976;Bouwma and Herrnkind, 2009;Staaterman et al, 2010), and social communication (Berrill, 1976;Silliman et al, 2003;Buscaino et al, 2011). Invertebrate sounds are also produced as a by-product of activities such as swimming and feeding (Radford et al, 2008a;Freeman et al, 2014;Coquereau et al, 2016). Sound production and reception has clear adaptive value for marine organisms (Bradbury and Vehrencamp, 1998), and the combination of bioacoustic signals produced in underwater habitats provides rich sensory information, forming a major component of the ambient acoustic environment, or "soundscape" (Cotter, 2008;Pijanowski et al, 2011).…”

Snapping shrimp are perhaps the most pervasive sources of biological sound in the ocean. The snapping sounds of cryptic shrimp colonies in shallow coastal habitats worldwide create a near-continuous crackling with high spatiotemporal variability, yet the underlying acoustic ecology is not well understood. This study investigated sound production rates and acoustic behavior of snapping shrimp species common in the Western Atlantic Ocean and Gulf of Mexico (Alpheus heterochaelis and Alpheus angulosus). Snap rates were measured in a controlled laboratory setting under natural light, temperature, and substrate conditions for shrimp held individually, in pairs, and in a ten-shrimp mesocosm, to test hypotheses that acoustic activity varies with time-of-day and social context. Spontaneous snapping was observed for 81 out of 84 solitary shrimp monitored. Time-of-day influenced snap output for individuals and same-sex pairs-higher rates occurred during dusk and night, compared to daylight hours, but this pattern was inconsistent for opposite-sex pairs and a mixed-sex group. These laboratory results provide insight into behavioral rhythms that may influence snapping patterns in natural populations, and underscore the limited understanding of a major sound source in marine environments.

“…The sea urchins, Psammechinus miliaris and Paracentrotus lividus , could participate to these differences because they produce sounds in the f p range of 39–49 kHz [ 15 ], and they were, respectively, eight and threefold more abundant, in the unfished than in the fished maerl beds. Another species that could be responsible of these differences in frequency diversity is the squat lobster, Galathea squamifera , present only in unfished bed samples and producing sounds at an f p of about 25 kHz [ 18 ].…”

Marine communities face anthropogenic pressures that degrade ecosystems. Because underwater soundscapes carry information about habitat quality, we explored whether destructive impacts of fishing could be evaluated via the soundscape. Maerl beds are recognized as biodiversity hotspots and they experience major worldwide degradation owing to fishing. We collected field acoustic recordings in maerl beds exposed to different fishing practices. We found that unfished maerl beds were threefold louder and exhibited sound frequencies more diversified than those recorded in fished maerl beds. Analyses of associated fauna samples indicated that snapping shrimps provided a major contribution to the maerl bed soundscape. Moreover, sea urchins and squat lobsters most likely contributed to differences between the soundscapes of unfished and fished maerl beds. Our results supported the idea that the soundscape can provide valuable information on maerl bed ecosystem health related to fishing activity.
