Hooded seal
Hooded seal milk is the sweetest in the world.
Hooded seals have a light gray to blue-gray coloration with irregularly shaped light or dark blotches.
Male: Males exhibit a characteristic enlarged nasal cavity (hood) which is inflated for display during courtship and as an aggressive posture for defense.
Hooded seals belong to the scientific order Pinnipedia, which includes seals, sea lions, and walruses.
Seals differ from sea lions in a number of ways, including having shorter, stouter flippers, and no visible earflaps.
Hooded seals are named for the bi-lobed hood, an enlargement of the nasal cavity on the heads of males. The male can inflate the hood and move air back and forth between the two lobes. In addition, the male can also inflate a bright, red, membranous "balloon" that usually originates from the left nostril. The inflated hood and balloon are often used in visual displays for courtship, for dominance, and as a threat.
