Estimated population: 85,000, endangered in Alaska, IUCN Red list
Ways to identify this species: light buff to reddish brown fur, lightly darker on chest and belly, 7.5-11 feet in length
Biology- Steller
sea lions are distributed across the North Pacific Ocean rim from
Northern Japan and Russia, the Aleutian Islands, central Bering Sea,
southern coast of Alaska, and south to the Channel Islands of
California.
- During the May through July breeding
season, steller sea lions congregate at more than 40 rookeries, where
adult males defend territories, pups are born, and mating takes place.
- Opportunistic
predators, steller sea lions feed on a variety of fish and cephalopods
including walleyed pollock, salmon and squid.
- Male stellers can weigh up to 2,400lbs. and females up to 800lbs.
Threats- Steller
sea lions were the most abundant marine mammal until their precipitous
decline in the early 1980's. The reasons for the decline are not known,
but may be related to the depletion of pollock and other fish from
critical habitat areas by bottom trawler fishing.
- These sea lions are vulnerable to entanglement in fishing gear.
