Sea elephant \Sea" el"e*phant\ (s[=e]" [=e]"[-e]*fant). (Zool.) 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.
