A Narwhal tusk, (Monodon monoceras), 19th century, 206cm longNote: The Narwhal is a species of whale (cetacean) most closely related to the Beluga Whale and the Irrawaddy Dolphin, it is still living today in the Arctic Ocean. Male Narwhals are easily identified by their single, exceedingly long, spiralling tusk, which is actually a tooth that projects from the left side of the upper jaw to form a left-handed helix. While the body of an adult male can grow up to lengths of 18 feet, the tusk can grow up to 5 to 10 feet—an extraordinary percentage of the body’s overall length. Like the tusks of elephants, Narwhal tusks do not regenerate if they are broken; unlike elephant tusks, the Narwhal tusks displays a hollow that runs nearly the full length.CITES Appendix I, Annex A With CITES A10 licence No.622593/01Please refer to department for condition report
