Colour thresholds in a coral reef fish
Coral reef fishes are among the most colourful animals in the world. Given the diversity of lifestyles and habitats on the reef, it is probable that in many instances coloration is a compromise between crypsis and communication. However, human observation of this coloration is biased by our primate visual system. Most animals have visual systems that are 'tuned' differently to humans; optimized...
متن کاملRegional Endothermy in a Coral Reef Fish?
Although a few pelagic species exhibit regional endothermy, most fish are regarded as ectotherms. However, we document significant regional endothermy in a benthic reef fish. Individual steephead parrotfish, Chlorurus microrhinos (Labridae, formerly Scaridae) were tagged and their internal temperatures were monitored for a 24 h period using active acoustic telemetry. At night, on the reef, C. m...
متن کاملA multi-agent simulation model of fishery fleet dynamics for the Queensland coral reef line fishery
We present a computational model of fishing fleet dynamics for the Queensland coral reef line fishery. The model runs in a two dimensional space with agents moving between port and the collection of available reefs. The model of rationality is based on the haystack models of game theory, such that the agents are aware of what other boats are doing and seek to maximise yield with consideration o...
متن کاملOcular media transmission of coral reef fish — can coral reef fish see ultraviolet light?
Many coral reef fish are beautifully coloured and the reflectance spectra of their colour patterns may include UVa wavelengths (315-400 nm) that are largely invisible to the human eye (Losey, G. S., Cronin, T. W., Goldsmith, T. H., David, H., Marshall, N. J., & McFarland, W.N. (1999). The uv visual world of fishes: a review. Journal of Fish Biology, 54, 921-943; Marshall, N. J. & Oberwinkler, J...
متن کاملColour vision in coral reef fish.
Over many millions of years, sea creatures have developed a range of light reflectance properties. One example is the large variation in the patterns and colours of fish inhabiting the world's coral reefs. Attempts to understand the significance of the colouration have been made, but all too often from the perspective of a human observer. A more ecological approach requires us to consider the v...
