ascrotal (not comparable)
- (zoology) Existing without a scrotum.
- 2001, Frances M. D. Gulland, CRC Handbook of Marine Mammal Medicine:
- The primary locomotory muscles of terrestrial mammals are appendicular, so much of the locomotory heat energy of the muscle is transferred to the environment rather than directed into the body cavities; this is not the case for ascrotal marine mammals, whose primary locomotory muscles surround the abdominal and pelvic cavities.
