Pulse sound generation, anterior swim bladder buckling and associated muscle activity in the pyramid butterflyfish, Hemitaurichthys polylepis.
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 butterflyfish, Hemitaurichthys polylepis, a member of the socially and ecologically diverse reef fish family Chaetodontidae. In the field, fish produce...
متن کاملIntra- and Intersexual swim bladder dimorphisms in the plainfin midshipman fish (Porichthys notatus): Implications of swim bladder proximity to the inner ear for sound pressure detection.
The plainfin midshipman fish, Porichthys notatus, is a nocturnal marine teleost that uses social acoustic signals for communication during the breeding season. Nesting type I males produce multiharmonic advertisement calls by contracting their swim bladder sonic muscles to attract females for courtship and spawning while subsequently attracting cuckholding type II males. Here, we report intra- ...
متن کاملAcoustic Model of Body and Swim Bladder for Target Identification
This paper discusses the Target Strength (TS) results offish from in situ measurement at the life sea habitat compared to acoustic model. In situ measurement of fish Selarboops (Oxeye scad) and Megalaspiscordyla (Torpedo scad) have been deployed using Scientific Echo Sounder. Laterally and dorsally X-ray imaged of fish have been deployed to perform fish body and swim bladder morphology. Length,...
متن کاملThe Secretion of Oxygen into the Swim-bladder of Fish
Fish were maintained in sea water equilibrated with a gas mixture containing a non-equilibrium mixture of the three molecular species of oxygen, O(18)-O(18) (mass 36), O(18)-O(16) (mass 34), and O(16)-O(16) (mass 32). Analyses in the mass spectrometer, of the gases secreted into the swim-bladder showed that no change in the relative abundance of these three molecular species had occurred during...
متن کاملBuckle up
Electrically conducting fluids can generate a magnetic dynamo when layers of fluid slide past one another, often at different rates. Known as shear, this is how the Earth and the Sun produce magnetic fields. But exactly how large-scale spatial coherence over the entire surface of the Sun can arise at high magnetic Reynolds numbers, as lines of magnetic field are dragged along by fluid flow, has...
