Unlike true seals, sea lions have earflaps and can rotate their hind-flippers for easier walking on land. Male Steller sea lions may weigh up to 1,300 lbs (590 kg) while females average only 600 lbs (270 kg). Besides weighing more, a dominant bull is easily spotted along exposed sections of rock along the shore, called haul-outs or rookeries, by his distinct body language.
Though Steller sea lions were once considered threatened, they have recovered in many parts of Southeast Alaska. Sea lions often come into conflict with fishermen due to their habit of stealing fish off fishing lines.
