Introduction


Narwhals, the unicorns of the sea, are very mysterious creatures that are not widely known. They are whales with many fascinating features and historical value. This research paper is answering the question, “What are Narwhals?”.


General Description


Monodon Monoceros, Latin for “one tooth, one horn”#; or Narhval, Norwegian for “corpse whale” , because of it mottled coloration suggests a bloated corpse#.Narwhals are in the white whale family, along with the beluga, but are actually covered with spots of black, white, gray-green, and cream.

Males and females are born with two teeth pointing forward in the upper jaw#. The left tooth of the male grows long and spirals counter clockwise toward the tip. On rare occasions there have been Narwhals with twin tusks. Research on Narwhals supports the idea that the tusk is both a weapon and a symbol of dominance in ritual displays#. Some other ideas about what the tusk is used for include the following: ice breaker or and instrument to poke breathing holes in ice#; rake to stir up the sea bottom for food#; skewer to impale prey species#.
