...Craig A. Radford; Jenni A. Stanley ABSTRACT The sensory systems of crustaceans (aquatic decapods and stomatopods) have adapted to a diverse range of aquatic ecosystems. Sound production in aquatic crustaceans is more widespread than previously thought, and has been shown to play a major role...

... of pulsatile sounds and a distinct postural display – extension of a hypertrophied lower jaw, a morphological trait not present in other Danionella species – during aggressive but not courtship interactions. Females show no evidence of sound production or jaw extension in such contexts. Novel pairs of size...

... by higher amplitudes or rates of calling, but such acoustic compensation mechanisms may incur energetic costs if sound production is expensive. The costs of whistling in bottlenose dolphins ( Tursiops truncatus ) have been reported to be much higher (20% of resting metabolic rate, RMR) than theoretical...

.... Communication Evolution Sound production Energy Phylogenetic signal Calling is a conspicuous way of attracting a potential mate and is thus thought to be associated with elevated energy usage and evolutionary fitness costs ( Symes et al., 2015 ). These signals have associated metabolic costs...

... near the fish. During search and capture of fish, free-swimming dolphins carried cameras to record video and sound. A hydrophone in the far field near the fish also recorded sound. From these two perspectives, we studied the time course of dolphin sound production during fish capture. Our observations...

...Kelly S. Boyle; Ségolène Riepe; Géraldine Bolen; Eric Parmentier ABSTRACT A variety of teleost fishes produce sounds for communication by vibrating the swim bladder with fast contracting muscles. Doradid catfishes have an elastic spring apparatus (ESA) for sound production. Contractions of the ESA...

... to form a single echolocation click with a higher source level, broader bandwidth and larger potential for beam steering than if produced by a single pair of phonic lips. Here, we test that hypothesis by measuring the sound production of five echolocating delphinids using hydrophones around the animals...

... sound production swimbladder rib cage resonance Among vertebrates, teleost fishes have evolved the largest diversity of sonic organs, including stridulation of bony structures, plucking of stretched tendons and contraction of intrinsic and extrinsic sonic muscles that excite swimbladder...

...Kelly S. Boyle; Timothy C. Tricas SUMMARY Many teleost fishes produce sounds for social communication with mechanisms that do not involve swim bladder musculature. Such sounds may reflect physical attributes of the sound-production mechanism, be constrained by body size and therefore control signal...

... are generated by rapid contractions of sonic muscles that insert on a broad tendon surrounding ventrally the cranial sac of the swimbladder. The piranha swimbladder is thought to play an important role in sound production as an impedance-matching device and as a resonator. However, the vibratory capacities...

... of sound production for caterpillars and rare for insects in general. The North American walnut sphinx ( Amorpha juglandis ) produces whistle ‘trains’ ranging from 44 to 2060 ms in duration and comprising one to eight whistles. Sounds were categorized into three types: broadband, pure whistles and multi...

...Kelly S. Boyle; Timothy C. Tricas SUMMARY Acoustic behaviors are widespread among diverse fish taxa but mechanisms of sound production are known from relatively few species, vary widely and convergent mechanisms are poorly known. We examined the sound production mechanism in the pyramid...
