narwhal

plural narwhals · alternative narwal · alternative narwhale

1. An Arctic toothed whale (Monodon monoceros) that grows to about 20 feet (6 meters) long, the male having a single horn-like tusk, a twisted, pointed cuspid that projects forward.

   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.

   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.
