A mesotherm (from Greek μέσος mesos "intermediate" and thermē "heat") is a type of animal with a thermoregulatory strategy intermediate to cold-blooded ectotherms and warm-blooded endotherms. (wikipedia.org)
The first trait distinguishes mesotherms from ectotherms, the second from endotherms. (wikipedia.org)
The term 'mesothermy' was originally coined to advocate for an intermediate status of non-avian dinosaur thermoregulation, between endotherms and ectotherms. (wikipedia.org)

Ectotherms are able to control their body temperatures via a combination of behavioral and physiological changes. (difference-between.net)
In cold weather, some ectotherms enter hibernation, or a state of torpor, which may last for a day or a year depending on the species, and thus restrict their movement and some may not be able to survive the season, as their metabolism rate and body temperature decreases and, in some animals like wood frogs, their metabolism stops. (difference-between.net)
Instead of being impacted by the ambient temperature, like Ectotherms are, Endotherms maintain a constant internal temperature in order to keep their metabolisms running smoothly. (difference-between.net)
