# Tortoises "hibernate", but a tortoise isn't endothermic

1. Apr 29, 2015

In http://en.wikipedia.org/wiki/Hibernation, "hibernation" is defined as being restricted to endotherms.
But lots of sites, such as http://www.anapsid.org/hibernation.html, claim that ectotherms can also hibernate: for example, tortoises.
First: which definition is correct? If Wikipedia's definition is correct, what is a tortoise doing all those months?
