Sensory Hairs in the Bowhead Whale, Balaena mysticetus (Cetacea, Mammalia)
ABSTRACT We studied the histology and morphometrics of the hairs of bowhead whales ( Balaena mysticetus ). These whales are hairless except for two patches of more than 300 hairs on the rostral tip of the lower lip and chin, the rostral tip of the upper lip, and a bilateral row of approximately ten...
