cold blooded
Lacking internal heat
Cold-blooded describes animals whose body temperature changes with their environment—reptiles, fish, amphibians—rather than being internally regulated like mammals.
The figurative sense dominates everyday speech: a cold-blooded act is calculated and merciless, done without emotion or remorse.
Cold-blooded murder suggests premeditation rather than passion.
Someone cold-blooded seems to lack normal human warmth or feeling.
