Fish thermoregulation
WebDescribe thermoregulation of endothermic and ectothermic animals; ... The countercurrent adaption is found in many animals, including dolphins, sharks, bony fish, bees, and hummingbirds. In contrast, similar adaptations can help cool endotherms when needed, such as dolphin flukes and elephant ears. ... Webthermoregulation, also called Heat Regulation, the maintenance of an optimum temperature range by an organism. Cold-blooded animals (poikilotherms) pick up or lose heat by way of the environment, moving from one place to another as necessary. Warm-blooded animals (homoiotherms) have additional means by which they can heat and cool …

The marine teleosts however have not gone along this path, they evolved another way of dealing with the imbalance. Their preferred internal ionic balance is about 350 mgs/l, or one third of that of the sea. Osmoregulation: movement of water and ions in saltwater (marine) fish.
WebJan 1, 2014 · Reliable method of studying of fish thermoregulatory behavior is the assessment of final selected temperature (FST) in a thermal gradient in long-duration … WebLarge fish like tuna and sharks generate and conserve enough heat to raise their body temperature above that of the surrounding water, but unlike a true endotherm, they don't maintain a specific body temperature. Even some insects can use metabolic heat to increase body temperature by contracting their flight muscles!
WebTo date, "no one knows what the optimal ratio in the diet is for these two families of fats." [5] Science writer Susan Allport writes that the current ratio in Japan is associated with a very low incidence of heart and other diseases.
