WebbThe high energy requirement for thermoregulation (about 85%) would, in the absence of huddling, probably exceed the total energy reserves. The data suggest that walking 200 km (from the sea to the rookery and back) requires less than 15% of the energy reserves of a breeding male emperor penguin initially weighing 35 kg. WebbThermoregulation is the ability of an organism to keep its body temperature within certain boundaries, ... (such as the mousebird and emperor penguin) it allows the sharing of body heat (particularly amongst juveniles). This allows the individuals to increase their thermal inertia (as with gigantothermy) and so reduce heat loss. boyfriend comic goth
