mesotherm

plural mesotherms

1. biologyAn animal that adjusts its body to a metabolically favourable temperature using a context-dependent balance of internal metabolically-produced heat and external-environmentally derived heat.

   The large terrestrial and marine reptiles of the Mesozoic were likely mesotherms, which maintained high body temperatures by virtue of their large size and whose metabolism approached that of endotherms.
