But, oh, what a tooth. <\/p><p>Not for nothing is this Arctic whale\u2019s scientific name\u00a0<em>Monodon monoceros<\/em>, from the Greek for &#8220;one-tooth one-horn.&#8221; <\/p><figure class=\"wp-block-image size-full\"\/><h2 class=\"wp-block-heading\">How long does a narwhal tusk grow?<\/h2><p>Projecting straight forward rather than downwards from an otherwise toothless mouth, it emerges through the top lip, twisting anticlockwise as it grows. Without it, a 6m-long whale would be a 4m-long whale. No wonder narwhals\u2019 tusks were long prized and traded as unicorn horns.<\/p><h2 class=\"wp-block-heading\" id=\"h-what-do-narwhal-use-their-tusk-for\">What do narwhal use their tusk for?<\/h2><p>The fact that only the males have tusks suggests they are there for the purposes of sexual display, like a peacock\u2019s tail, advertising a male\u2019s quality to potential mates or rivals. But unlike peacocks\u2019 tails, narwhals\u2019 tusks are more than just eye-candy. They seem to have a few practical uses, too.<\/p><p>Males have been documented swishing them back and forth to stun fast-moving prey, for example, much like sailfish use their elongated snouts. Dotted with nerve endings, they might well have a sensory function, too \u2013 detecting sound, smell or touch, perhaps. And it\u2019s not hard to imagine how they could make a hungry orca think twice about launching an attack. Females, though, seem to get on perfectly well without them.<\/p><figure class=\"wp-block-image size-full\"><a href=\"https:\/\/www.youtube.com\/watch?v=7sZMv3xKFGY\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"400\" src=\"https:\/\/c02.purpledshub.com\/uploads\/sites\/62\/2024\/03\/narwhal-1-1.jpg\" alt=\"\" class=\"wp-image-97001\"\/><\/a><figcaption class=\"wp-element-caption\"><em>Drone footage of a narwhal surfacing for breath in the Arctic \u00a9 Paul Nicklen \/ National Geographic Stock \/ WWF-Canada<\/em><\/figcaption><\/figure><h3 class=\"wp-block-heading\">Want to find out more?<\/h3><p>Check out our comprehensive <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/mammals\/narwhal-guide\" target=\"_blank\" rel=\"noreferrer noopener\">guide to narwhals<\/a>, as well as a <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/marine-animals\/minke-whale-facts\" target=\"_blank\" rel=\"noreferrer noopener\">guide to minke whales<\/a>, <a href=\"https:\/\/www.discoverwildlife.com\/animal-facts\/marine-animals\/blue-whale-facts\" target=\"_blank\" rel=\"noreferrer noopener\">blue whale facts<\/a> and <a href=\"https:\/\/www.discoverwildlife.com\/how-to\/watch-wildlife\/how-where-to-see-whales-uk\" target=\"_blank\" rel=\"noreferrer noopener\">where to see whales around the UK<\/a>.<\/p> <\/body><\/html>\n<hr class=\"no-tts wp-block-separator\"\/>","protected":false},"excerpt":{"rendered":"<p>What is the narwhal&#8217;s tusk?
