1. Narwhal Dental Hygiene

Swimming in the Arctic waters like a unicorn with a PhD in dentistry, narwhals know a thing or two about oral hygiene, or lack thereof: these mysterious creatures possess a single elongated, spiraling tusk that can reach up to 9 feet, but have no teeth inside their mouths, swallowing large fish whole and having only the left canine tooth erupt through their upper lip - with females and the occasional male boasting secret, unerupted tusks as well!

2. Built-in GPS Tusk

Say hello to the Unicorn of the Sea, equipped with a built-in GPS on their pointy hat: Narwhals possess a unique, elongated tusk that acts as a sensory organ, allowing them to detect changes in water pressure, salinity, and temperature, thanks to open channels in the tusk's porous cementum layer and connected nerve pathways.

Move over, unicorn: there's a new "king of really, really big pointy things on heads" in town! These horned heavyweights know how to joust it out for love, piercing through the competition with Cupid's harpoon: Male narwhals use their massive, impressive tusks - which are actually modified teeth - for combat and mating rituals, with the strongest individuals boasting tusks up to 2.5m long, displaying their sheer power and prowess to attract potential partners.

5. Sherlock Holmes of the Sea

Riddle me this: what has a tooth up to 10 feet long, and the ability to sense things that would make Sherlock Holmes envious? The unassuming narwhal, of course: Its spiraled tusk is actually an enlarged tooth with more than 10 million nerve endings inside, and some even boast a crime-solving duo of two tusks!

6. Arctic Undercover Climate Agents

Call them the Arctic's undercover agents seeking ice breakers: Narwhals use their tusks as sensory organs that help navigate through sea ice, detecting changes in temperature, water pressure, particle gradients, and motion! This could potentially turn our tusked companions into indicators of arctic climate and environmental change, without so much as a dependence on salt levels or GPS.

7. Size Matters in Sea Unicorn Society

Move over, unicorn: there's a cooler, aquatic cousin with a majestic horn! Narwhals, the fanciful sea unicorns with their pointy protuberances, enjoy a merry-go-round in the ocean, not for any dramatic battle or deep-sea exploration, but for love and popularity: These tusks are primarily used for mating displays and establishing social hierarchy among the males of their pod, proving that size truly does matter in the enchanting underwater world of narwhals.

8. Old Souls with Horns

Feeling a bit "horny" with their spiral tusks, narwhals are the quirky unicorns of the sea: These Arctic-dwelling cetaceans are old souls with low genetic diversity and a history stretching back to the expansion of suitable habitats after the icy grip of the Last Glacial Maximum loosened, allowing them to flourish alongside their fellow polar marine buddies.

9. Majestic Spiral-Toothed Sea Unicorns

Step right up and behold the majestic unicorn of the sea, the dental wonder with a twist (pun intended!): narwhals possess a strikingly long (up to 9 feet!) and spiraling tusk—which is essentially a massive canine tooth—that sprouts from their maxillary bone and functions as the sea-creature's only visible tooth, predominantly found in the males with a less impressive version in the occasional female.

Whoever said "long in the tooth" was a bad thing clearly never met a narwhal: these dashing whale cousins of "unicorn of the sea" boast a massive 10-foot-long spiraling tusk, which is actually an overgrown canine tooth, believed to function as an extraordinary sensory organ with millions of nerve endings, enhancing their perception of the icy waters around them. Unicorns? They've got nothing on these guys.
