The horns were so sought after that the tusks of narwhals were passed off as unicorn horns and were widely traded. In the Middle Ages, unicorns were believed to be real creatures that inhabited faraway places, and their horns were thought to have magical properties. Medieval Monsters: Terrors, Aliens, Wonders, on view in the Kelvin and Eleanor Smith Foundation Exhibition Gallery through October 6, 2019, explores the function, deployment, and reception of monstrous images during the Middle Ages, including mystical creatures that remain familiar today, like dragons and unicorns. Now on view in Medieval Monsters at the Cleveland Museum of Art The Morgan Library & Museum, Gift of the Trustees of the William S.

Ink, tempera, and gold on vellum 15.6 x 10.5 cm. Illuminated by the Master of Edward IV (Flemish, active 1470–90). This sensitivity suggests that the narwhal tusk isn't something to be used haphazardly - you'll notice in the footage above that those hunting taps are extremely gentle.Detail. Bubbles then travel through the shaft and excite nerve endings at the base of the tooth near the head, sending signals to the brain about the narwhal's surroundings. Scientists suspect that the tooth plays a role in echolocation by allowing seawater to enter it through pores in its tip. Previous research had found that the narwhal tooth had foregone the protection of hard, external enamel to make it sensitive to even the tiniest of stimuli - and this appears to have given them the edge over all other echolocating species.

Like dolphins and other whales, they're able to navigate dark, murky waters by producing clicking sounds at a rate of up to 1,000 clicks per second, and using the echoes to reconstruct their surroundings based on how the sound waves bounce off nearby prey or rock formations. Late last year, researchers discovered that this tusk helps narwhals 'see' like no other species on Earth - when they measured the whales' echolocation skills, they found that they have the most directional sonar ever detected. Turns out, they are, as you can see in the footage below: The mystery of these 'horns' - which can grow up to 2.7 metres (9 feet) long - has led scientists to pose a number of possible functions, including signals of testicle size, navigation, and territorial battles.īut there's been one obvious gap in the evidence - these things look a whole lot like weapons, so are they using them to hunt too?

"This is an entirely new observation of how the tusk is used," Brandon Laforest, a senior specialist of Arctic species and ecosystems with WWF-Canada, told National Geographic. The footage was captured by two drones in Tremblay Sound, Nunavat, in northeastern Canada, which were operated by Adam Ravetch from the World Wildlife Fund (WWF) Canada and researchers from Fisheries and Oceans Canada. The behaviour addresses a biological mystery that's spanned decades - why these rare and elusive whales have evolved an extra-long left canine tooth that bursts through the upper lip and protrudes from the head like the horn of a unicorn.
