  • Summary1.Temperatures in the brain and eyes of mako and porbeagle sharks (Lamnidae) are 5°C warmer than the water while the brain and eye temperatures in six other species of pelagic sharks are within 0.1°C of water temperature.2.An orbital rete mirabile is present in the porbeagle and mako sharks but absent in the cranial vasculature of eleven other species of pelagic sharks.3.The orbital rete in the head of the porbeagle and mako sharks acts as a heat exchanger which conserves metabolic heat… CONTINUE READING
