“…Prior studies in other taxa demonstrated that fishes can detect sound pressure in the absence of a clear connection ( Figure 12D). This has been shown in the genus Stegastes (family Pomacentridae, damselfishes; Myrberg and Spires, 1980), Gadus (family Gadidae, cods; Sand and Enger, 1973), and recently in the African lungfish Protopterus (family Protopteridae, lungfishes, Christensen et al, 2015). It is assumed that in these families bladder wall oscillations are transmitted to the inner ears via the interjacent tissue (Hawkins, 1986).…”

“…There are three main ways to connect the gas bladder directly to the inner ear (Figures 12A-C) and to detect sound pressure. Pressure detection may even take place in the absence of such a direct connection, most likely because tissues between the bladder and inner ear transmit bladder oscillations (e.g., Myrberg and Spires, 1980; see Section Cichlidae; Figure 12D). …”

“…To date it remains elusive how certain inner ear modifications are correlated to certain aspects of auditory abilities. Moreover, only few studies successfully disentangle the detection of the amounts of particle motion and sound pressure in fishes (e.g., Myrberg and Spires, 1980;Christensen et al, 2015).…”

“…Sonic organs and sound communication are found in taxa with (mormyrids, catfish, piranhas, some labyrinth fishes) and without accessory hearing structures. Sound-producing taxa lacking accessory hearing structures can either be mainly particle motion sensitive such as toadfishes (Batrachoidiformes), sculpins (Cottiformes), and gobies (Gobiidae, Perciformes), or also display sound pressure sensitivity such as damselfish (Pomacentridae) and cods (Gadidae; Sand and Enger, 1973;Myrberg and Spires, 1980). Comparative studies among labyrinth fishes show that closely related genera may be vocal or non-vocal-such as croaking gouramis (genus Trichopsis) and Siamese fighting fish (genus Betta)-without differing in inner ear ultrastructure or accessory hearing organs (Ladich and Popper, 2001).…”

Diversity in Fish Auditory Systems: One of the Riddles of Sensory Biology

An astonishing diversity of inner ears and accessory hearing structures (AHS) that can enhance hearing has evolved in fishes. Inner ears mainly differ in the size of the otolith end organs, the shape and orientation of the sensory epithelia, and the orientation patterns of ciliary bundles of sensory hair cells. Despite our profound morphological knowledge of inner ear variation, two main questions remain widely unanswered. (i) What selective forces and/or constraints led to the evolution of this inner ear diversity? (ii) How is the morphological variability linked to hearing abilities? Improved hearing is mainly based on the ability of many fish species to transmit oscillations of swim bladder walls or other gas-filled bladders to the inner ears. Swim bladders may be linked to the inner ears via a chain of ossicles (in otophysans), anterior extensions (e.g., some cichlids, squirrelfishes), or the gas bladders may touch the inner ears directly (labyrinth fishes). Studies on catfishes and cichlids demonstrate that larger swim bladders and more pronounced linkages to the inner ears positively affect both auditory sensitivities and the detectable frequency range, but lack of a connection does not exclude hearing enhancement. This diversity of auditory structures and hearing abilities is one of the main riddles in fish bioacoustics research. Hearing enhancement might have evolved to facilitate intraspecific acoustic communication. A comparison of sound-producing species, however, indicates that acoustic communication is widespread in taxa lacking AHS. Eco-acoustical constraints are a more likely explanation for the diversity in fish hearing sensitivities. Low ambient noise levels may have facilitated the evolution of AHS, enabling fish to detect low-level abiotic noise and sounds from con-and heterosopecifics, including predators and prey. Aquatic habitats differ in ambient noise regimes, and preliminary data indicate that hearing sensitivities of fishes vary accordingly.

“…Studies into the hearing abilities of adults from the same family or genus have produced conflicting results. Different pomacentrid species have similar hearing abilities (Kenyon 1996, Myrberg & Spires 1980 as do 2 members of the genus Astyanax (Characidae) that inhabit vastly different environments (Popper 1970). Conversely, the families Holocentridae (Coombs & Popper 1979) and Sciaenidae (Ramcharitar et al 2004(Ramcharitar et al , 2006 contain some species that have high hearing sensitivities and other species with relatively poor hearing sensitivities.…”
