Supercooling is also a common feature in some insect, reptile, and other ectotherm species. This could be fatal to an endotherm, and also highly dangerous to an ectotherm. The Alameda whipsnake is a diurnal ectotherm that is often seen foraging in the daytime. "V. griseus" is a cold-blooded ectotherm whose behaviors therefore depend on the outside temperatures. As the external temperature increases, ectotherm metabolisms increase as well, increasing their demands for oxygen.
