Male Narwhal or Unicorn (Monodon monoceros) and Greenland Shark (Somniosus microcephalus)
from An account of the Arctic regions with a history and description of the northern whale-fishery, by W. Scoresby. 1820. P. 588, Vol. II. Plate XV
Narwhals, along with turtles, are my favorite animals.
Great Idea, I’m fully using it!
