Nemertina \Nem`er*ti"na\ (n[e^]m`[~e]r*t[imac]"n[.a]), prop. n.
pl. [NL. See {Nemrtes}.] (Zo["o]l.)
An order of helminths usually having a long, slender, smooth,
often bright-colored body, covered with minute vibrating
cilia; -- called also {Nemertea}, {Nemertida}, and
{Rhynchoc[oe]la}.

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.
