Distribution:

Hooded seals inhabit the Arctic Ocean and North Atlantic.  Hooded seals do migrate during the summer and fall and can drift far from their northern breeding grounds.

Description:

These seals are named for their elastic bi-lobed nasal cavity or “hood” that adult males can inflate and extend.  They have black heads with a silver-gray coat covering the rest of their body.  Pups have a blue-gray coat and whitish bellies.

Diet in the Wild: Crustaceans, squid, starfish, mussels and fish such as capelin and cod.
Habitat:

Hooded seals are founding living on drifting pack ice in deep waters. Though they may drift to warmer waters, they survive best in colder climates.

Reproduction:

The breeding season for Hooded seals begins in late winter and lasts through April.  Females reach sexual maturity at about 3-6 years of age and males at about 5-7 years of age.  When on the breeding ground, animals will stay there for 2-3 weeks to produce young and complete their annual molt before beginning their migration cycle. Once born, pups are weaned in a mere 3-5 days, which is the shortest time of any known mammal.

Conservation Status:

The Northwest Atlantic Fisheries Organization (NAFO) began managing the seal harvesting in the 1970s in international waters.  They also prohibited the hunting of pups.  A seal management plan was put into effect in 1992.

Threats in the Wild:

Historically, these seals were heavily hunted for oil, leather and the pups uniquely colored pelt; Illegal hunting still continues.  These seals are also often caught as by-catch.

Fun Facts: Besides being called Hooded seals, they are also referred to as the bladder-nosed seal.
