Serpent \Ser"pent\, n. [F., fr. L. serpens, -entis (sc. bestia),
   fr. serpens, p. pr. of serpere to creep; akin to Gr. ???,

         and pressing them against objects, and partly by using

         rough surfaces. Many species glide swiftly over the
         ground, some burrow in the earth, others live in trees.
         A few are entirely aquatic, and swim rapidly. See
         {Ophidia}, and {Fang}.
