Aquatic environments encompass the world's most extensive habitats, rich with sounds
produced by a diversity of animals. Passive acoustic monitoring (PAM) is an increasingly …

Fishes have evolved multiple mechanisms for sound production, many of which utilize sonic
muscles that vibrate the swimbladder or the rubbing of bony elements. Sonic muscles are …

The underwater environment is more and more being depicted as particularly noisy, and the
inventory of calling fishes is continuously increasing. However, it currently remains unknown …

In addition to briefly reviewing sound-producing mechanisms, this chapter focuses on an
under-appreciated evolutionary process, exaptation, which could aid in understanding the …

Abstract Mesophotic Coral Ecosystems remain largely unexplored. The aim of this study was
to determine how the acoustic fish biodiversity varied depending on the depth and the type …

Background Marine soundscape is the aggregation of sound sources known as geophony,
biophony, and anthrophony. The soundscape analysis, in terms of collection and analysis of …

Abstract The Acoustic Complexity Index (ACI) is increasingly applied to the study of
biodiversity in aquatic habitats. However, it remains unknown which types of acoustic …

Rare and cryptic fish species such as the cusk‐eel Ophidion rochei (Műller,
1845)(Ophidiiformes), an endemic sand‐dwelling Mediterranean fish, are likely to go …

Sounds from toadfish Opsanus sp., and 4 other suspected fish sounds were identified in
passive acoustic recordings from fixed recorders and autonomous underwater vehicles in …

A recurrent question arising in fish bioacoustics research concerns the number of vocal fish
species that may exist. Although it is not possible to provide a precise globally valid number …
