Ontogenetic changes in the response properties of individual, primary auditory afferents in the vocal plainfin midshipman fish Porichthys notatus Girard.
The auditory system of adult midshipman fish Porichthys notatus Girard is an important sensory receiver system used during intraspecific social communication to encode conspecific vocalizations, but the response properties and function of this system in the pre-adult stages are unknown. Midshipman fish, like other teleosts, use the saccule as the main acoustic end organ of the inner ear. In thi...
متن کاملBioluminescence Maintenance in Juvenile Porichthys notatus.
Bioluminescence in the midshipman fish, Porichthys notatus from the Santa Barbara coastal region, was quantified from onset through the first two years of life. Maximum light emission was 2.5 x 109 photons s-1 upon leaving the nest and reached 2.0 x 1010 photons s-1 within the first year. These intensities may be sufficient for counterillumination in moon or starlight over most of the depth ran...
متن کاملSound source localization by the plainfin midshipman fish, Porichthys notatus.
The aim of this study was to use plainfin midshipman fish (Porichthys notatus) as a general model to explore how fishes localize an underwater sound source in the relatively simple geometry of a monopole sound field. The robust phonotaxic responses displayed by gravid females toward a monopole sound projector (J-9) broadcasting a low-frequency (90 Hz) tone similar to the fundamental frequency o...
متن کاملDiet and cannibalism in plainfin midshipman Porichthys notatus.
The macroscopic and microscopic diversity of potential food items available in the nests of plainfin midshipman Porichthys notatus were quantified and compared with items that were found in the stomach and intestine (digestive tract) of the guarding males. In this species, males occur as one of two possible reproductive morphs: guarder males that care for young and sneaker males that parasitize...
متن کاملDivergent hypoxia tolerance in adult males and females of the plainfin midshipman (Porichthys notatus).
In the summer, the plainfin midshipman (Poricththys notatus) migrates to reproduce in the nearshore environment, where oxygen levels are influenced by the tidal cycles. Parental males establish nests under rocks in the intertidal zone, where they reside until the eggs they guard are fully developed. In contrast, females and sneaker males leave the nests shortly after spawning. We examined the p...
