Hydras
(gcide) | Hydra \Hy"dra\, n.; pl. E. Hydras, L. Hydr[ae]. [L. hydra,
Gr. "y`dra; akin to "y`dwr water. See Otter the animal,
Water.]
1. (Class. Myth.) A serpent or monster in the lake or marsh

3. (Zool.) Any small fresh-water hydroid of the genus
Hydra, usually found attached to sticks, stones, etc.,
by a basal sucker.
[1913 Webster]
Note: The body is a simple tube, having a mouth at one
extremity, surrounded by a circle of tentacles with
which it captures its prey. Young hydras bud out from
the sides of the older ones, but soon become detached
and are then like their parent. Hydras are remarkable
for their power of repairing injuries; for if the body
be divided in pieces, each piece will grow into a
complete hydra, to which fact the name alludes. The
zooids or hydranths of marine hydroids are sometimes
called hydras.
[1913 Webster]
4. (Astron.) A southern constellation of great length lying
