Narwhal

The narwhal is the unicorn of the sea.

Esther thought the narwhal was so cute.

The narwhal is an odontocete or toothed whale, but is different from all other toothed whales in that it has no teeth in its mouth. Instead, male narwhals have a single long, straight tooth (or tusk) that protrudes two to three meters out of the upper left jaw. Females almost never have a tusk. The tooth grows in a counterclockwise spiral.

Is that a narwhal?

Moreover, both narwhals and bowheads can occur in late summer in southern Prince Regent Inlet (coming from Lancaster Sound) and may reach Fury and Hecla Strait and northern Foxe Basin.

Often, in the morning, narwhals played around the boat and reminded me of the dolphins, so far away in the North Atlantic. But these narwhals were not like the Atlantic sea-dogs; they had little of their flashing vibrancy; these Turkish narwhals were much more relaxed, and rolled over lazily, with a sigh, as if they were going to retire to a sofa and smoke a hookah.

At over 2.5 m in length, the tusk of the male narwhal (Monodon monoceros) is one the most impressive instruments of male-male competition among mammals.
