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

Gold Member
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?

Thanks very much, Simon Bridge. The first article was very interesting not only in helping to answer my question but also in many other interesting facts; the second short article says that Wikipedia is technically right but is being pedantic.
