Move over, trunk-wielding circus stars: the real heavyweights are here with their flippers and blubber!

Seals: the original social distancers with a twist! From playing keep-away with their fellow seal buds to hosting pinniped parties with the California sea lions and Northern elephant seals - but never mixing with other species, of course: Harbor seals are sociable animals that form loosely-knit groups, maintaining personal space of one meter or more, and becoming less playful and less tolerant of close contact as they mature.
