Often referred to as the “Unicorn of the Sea”, the narwhal (also known as Narwhale) is a medium-sized toothed-whale distinct in its appearance, sounds, and swimming patterns. These oceanic animals are most notable for their protruding teeth, which many often mistake as horns but are, in fact, tusks! Spiraled, left-sided, and long, these tusks have been the narwhals’ most attractive and peculiar feature as well as the source of their endangerment.
