1. Seal Moonwalk Swimmers

Ever watched a seal do the moonwalk in the water and thought, "He must be a smooth criminal!"?

2. Heavyweight Elephant Seals

Move over, trunk-wielding circus stars: the real heavyweights are here with their flippers and blubber! Contrary to popular belief, elephant seals earned their name not from their snooty, elongated schnozzes, but because bull southern elephant seals reach a whopping 20 feet in length and top the scales at over 8,800 pounds. These seals have an affinity for sub-Antarctic and Antarctic waters, but watch out – they hit land every now and then for some good old-fashioned breeding time.

3. Blubber-rich Weddell Seals

Feeling a little chubby after that last cheat meal? Don't worry, you've got nothing on Weddell seals, the kings and queens of blubber town: These chunky treasures can rock up to 2 inches of blubber (weighing in at a whopping 240 kg or 530 lbs), bundling them up against Antarctic chills and keeping their energy reserves stocked for when they need to forgo trips to the underwater buffet.

Leopard seals might be the dentists' role models in the Antarctic dental community, constantly sporting braces to keep their smile just perfect: Their specially designed rear teeth come with interlocking gaps that act as a krill-straining superpower, making them one of few seal species that can munch on petite prey like a krill canapé.

6. Fierce Fur Seal Teeth & Toenails

Move over, land-shark dentists: The northern fur seal has a fishy buffet to tackle! Known for being the ultimate marine dental marauders, they wield a ferocious set of chompers that would make any tooth fairy tremble in her boots: In addition to their razor-sharp teeth numbering between 34 to 38, which they use to shred fish before gobbling them up, these furry flippers have a rather fashionable flipper-toe-nail arrangement! They can fold their hind flippers in half to make optimal use of the three nails on each flipper for a top-notch grooming session of their luscious fur coats.

Talk about a homing pigeon in a wetsuit: Female Antarctic fur seals can navigate back to within 12 meters of their birthplace when it's breeding season – their impeccable memory and keen sense of direction only improving with age! This fascinating fact not only helps researchers study the ecosystem of South Georgia, home to 97% of the world's Antarctic fur seals, but also reveals the huge impact of their breeding habits on the local plant life.

9. Social-distancing Harbor Seals

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.

Whisker Detectives

10. Whisker Detectives

Seals mustache you a question: do their whiskers detect fish or conduct underwater interviews? Funny as it may sound, it's actually the former: seals possess uniquely shaped whiskers that can sense disturbances in the water up to 100 meters away, helping them become adept hunters and inspiring scientists to improve artificial sensor systems for maritime vessels.

11. Elephant Seal Marathon Swimmers

Imagine if Seal, the singer, decided to switch careers and become a long-distance swimmer with impeccable timing and navigation skills: Elephant seals actually travel a whopping 10,000 kilometers in a 240-day foraging migration across the Northeast Pacific Ocean before returning to their breeding beaches just in time to give birth, only five days after arriving!

12. Hipster Seal Coats

Seal pups: nature's hipsters with their cozy, furry, lanugo coats. Except these coats are on preemies, and that's no laughing matter: these long, white, wavy furs show premature birth, leading to high mortality rates as their underdeveloped lungs and muscles leave them easy pickings for predators like coyotes.

13. Newborn Harbor Seal Phelps

Looking for a swimming sensation even Michael Phelps can't keep up with? Meet the newborn harbor seal pup: They can swim and dive minutes after being born, and journey over 100 miles from their birthplace within their first month, all while learning the ropes in seal nurseries for added protection against predators.

14. Logger Grey Seals

Anyone up for some aquatic planking? Seals seem to be natural experts: Grey seals practice "logging", a technique where they float horizontally near the water's surface and use their flippers to keep them steady. This ingenious method allows them to rest while foraging in the ocean for days on end.

Flirty Singing Seals

15. Flirty Singing Seals

If singing competitions were held under the sea, seals would give the Little Mermaid a run for her money: Male seals use their uniquely enchanting vocal calls to defend territories and attract females; some calls even reach up to 30 kilometers away, while harbor seals put on a flirty display of poses and low guttural noise to lure in the love interest.

16. Harp Seal Long-distance Callers

Who needs a cell phone when you've got nature's own roaming charges? These whiskered wonders, known as harp seals, are the ultimate long-distance callers: Equipped with an excellent sense of vision and a set of beaded "vibrissae" whiskers that detect low-frequency vibrations, these seals can efficiently locate fish and aquatic organisms during their extensive migratory journeys. Communicators-extraordinaire during breeding season, these ocean-roaming drifters are known for their assorted vocalizations like "bawling" hungry pups or "mumbling" playtime sounds, proving that long-distance relationships can work, even in the animal kingdom!

17. Elephant Seal Supermoms

Move over, superhero moms - there's a new cape-wearing, lullaby-singing, pup-raising queen in town: Only a tiny proportion of female elephant seals, dubbed "supermoms," are accountable for more than half of all pups born in a colony, as they manage to give birth to, nurse, and rear 10 or more pups throughout their long and prosperous lives while their young counterparts often don't survive long enough to procreate.

18. Born-to-Swim Pups

Who needs swimming lessons when you're a natural-born Phelps of the sea?: Seal pups can swim and hold their breath underwater for 2 minutes at only 2 days old, and they double their birth weight thanks to their mother's ultra-rich, 50% fat milk.

19. Hooded Seal Milkshakes

Seals could teach us a thing or two about milkshakes: they've mastered the art of thick, fatty, high-energy lactation! Behold the hooded seal mother: in just 3.6 days, she transfers monumental amounts of energy to her pups through milk that's a shocking 90% fat. Now that's a whole lot of seal blubber—216.3 of body energy, to be precise. It's all thanks to an enzyme called lipoprotein lipase (LPL), which supercharges both mom's milk and pup's growth. So next time you grab a shake, make it a seal-approved, LPL-infused special!
