Did you know?

The narwhal is a toothed whale found throughout arctic waters. Its Latin binomial, Monodon monoceros, is derived from the Greek words for "single-toothed" and "single-horned." Its English name (also sometimes spelled narwhale) comes from the Norwegian and Danish narvhal and the Swedish narval, words which are probably a modification of the Icelandic nárhvalur, which comes from the Old Norse nāhvalr. In Old Norse hvalr means "whale" and is akin to the Old English hwæl, the ancestor of the Modern English whale. The first element of nāhvalr is believed to be nār, the Old Norse word for "corpse," from the resemblance of the animal's color to that of a human corpse.
