Origin of hydra
After the Hydra, from Greek mythology, which grew two new heads every time one of its heads was cut off. The biology sense alludes to the budding method of asexual reproduction that the hydra practices, similar to growing new heads. The figurative sense refers to how the creature could not be killed by a swift, decisive solution (in contrast to a Gordian knot).
From Latin Hydra, the mythical serpent, originally from Ancient Greek ὕδρα (húdra), from Proto-Indo-European *údreh₂ (“aquatic”). Doublet of otter.
