Definition

A medium-sized Arctic whale (Monodon monoceros) famous for its long, spiral tusk, which is actually an elongated tooth protruding from its head. Narwhals are highly social marine mammals found in the waters around Greenland, Canada, and Russia.

Example Usage

The narwhal's tusk can grow up to 10 feet long and is covered with sensory nerves.

Origin

From Old Norse 'nár' (corpse) and 'hvalr' (whale), possibly referring to the whale's mottled skin appearance.

Fun Fact

Male narwhals are famous for their tusks, but females rarely develop them; the tusk's exact purpose remains debated, though it likely serves sensory and social functions.
