Here’s a nice sea lion ‘action picture’ from photographer Ken Lambert, for the Seattle Times.
Sea lions and seals differ primarily in that sea lions have visible ear flaps, large flippers for “walking” on land, and bark loudly, while true seals have ear holes, short flippers, and move by belly-sliding. Sea lions are generally larger, more social, and agile on land; seals are more solitary and streamlined for swimming. – Google AI Overview
