Novacula Caerulea: The Blue Fish.
Some of these Fish are twice the Bignesss of this; but I think
they are seldom found much larger. The Head is of an odd Structure
and like that of the Whale, which produces the Sperma Ceti; the
Mouth is small, each Mandible armed with a single Row of even Teeth
so closely joined that they seem entire Bones ; the Iris of the
Eye red. On the Back was a long pliant Finn, somewhat indented on
the Edge ; Behind the Gills were two Finns, one under the Abdomen,
and another behind the Anus ; the Tail forked; The whole Fish entirely
blue. They are frequently taken among the Bahama Islands, and in
most of the Seas between the Tropicks.
