     pl. [NL. See {Nemrtes}.] (Zool.)
     An order of helminths usually having a long, slender, smooth,

     Note: The mouth is beneath the head, and the straight
           intestine at the posterior end. They have a very
           singular long tubular proboscis, which can be everted
           from a pore in the front of the head. Their nervous
           system and blood vessels are well developed. Some of
           the species become over one hundred feet long. They are
           mostly marine and seldom parasitic; a few inhabit fresh
           water. The two principal divisions are Anopla and
           Enopla.
