Etymology

After the Hydra, from Greek mythology, which grew two new heads every time one of its heads was cut off. The first sense alludes to the budding method of asexual reproduction that the hydra practices, similar to growing new heads. The second sense refers to how the creature could not be killed by a swift, decisive solution (in contrast to a Gordian knot).

It was slain by Hercules. Hence, a terrible monster. Gorgons, and Hydras, and Chimeras dire. Milton.

3. (Zoöl.)

Definition: Any small fresh-water hydroid of the genus Hydra, usually found attached to sticks, stones, etc., by a basal sucker.

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.

4. (Astron.)

Definition: A southern constellation of great length lying southerly from Cancer, Leo, and Virgo.
