Macrorhinus proboscideus

资料来源 : Webster's Revised Unabridged Dictionary (1913)

Sea elephant \Sea" el"e*phant\ (Zo["o]l.)
   A very large seal ({Macrorhinus proboscideus}) of the
   Antarctic seas, much hunted for its oil. It sometimes attains
   a length of thirty feet, and is remarkable for the
   prolongation of the nose of the adult male into an erectile
   elastic proboscis, about a foot in length. Another species of
   smaller size ({M. angustirostris}) occurs on the coast of
   Lower California, but is now nearly extinct.
