How do poikilotherms thermoregulate
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 their bodies. WebThey also behaviorally thermoregulate by basking as needed in their shallow surface tunnels, which are warmed by the sun. Scientists have found that the somatosensory cortex, which is involved in the sense of touch, is unusually large. Nearly a third of it is dedicated to the animal's four, large incisors.
