Black-coated animals were found to have 18 percent lower heat loss in temperatures below −10 °C (14 °F), a 20 percent lower metabolic rate, and a non-shivering thermogenesis capacity that is higher than a gray morph. [14] Additionally, researchers of the color morph have noted a strong negative correlation with the frequency of black ...
The appearance of an amelanistic animal depends on the remaining non-melanin pigments. The opposite of amelanism is melanism, a higher percentage of melanin.
