Did you know that some sharks can keep parts of their body warm to allow them to move faster, swim for longer, see more clearly and think better?? Or, that basking sharks have a gigantic heart?! This week we are diving into the fascinating world of shark physiology and anatomy to learn about a special trait only found in a handful of species: regional endothermy. To take us on this journey of discovery we are joined by Dr Haley Dolton, marine biologist specialising in the physiology and ecology of large, regionally endothermic fishes!
