WebbMost cellular functions are limited to the range between 0°C and 40°C, Thermal limits To stay within those limits in spite of environmental conditions, animals have evolved thermoregulatory adaptations. Those adaptations give them certain thermal tolerances, which determine their geographic ranges. WebbThese adaptations control the loss of heat by regulating blood circulation. A wonderful network for heat recovery. The rete mirabile, Latin for “wonderful network”, is a counter-current heat exchange system. These networks are mainly found in poorly insulated regions such as the pectoral, dorsal, and caudal fins. if this peaks your interest
