“despite having no external ear lobes, can hear very well. Manatees emit sounds in the human auditory range and will make sounds, such as squeaks or squeals when frightened, playing or communicating”. A “cow and calf once separated by a flood-control gate vocalized constantly for 3 hours until reunited.”
