Endotherm
Endotherms were warm-blooded animals that could control their body temperatures through internal means such as muscle shivering, fat burning, and panting. 

Certain predatory vines found on Surata IV sought out warm-blooded beings and deliberately infected them with microbes. ()

In his "Ode to Spot" in 2369, Data noted that Spot was an "endothermic quadruped, carnivorous by nature." ()

The Voth used the term endotherm in relation to mammalian species, and considered them to not usually be very advanced. ()
