In particular, Sumerian, Babylonian, and Assyrian mythology celebrated the deeds of the war and hunting god Ninurta, whom the "Angim" credited with slaying 11 monsters on an expedition to the mountains, including a seven-headed serpent (possibly identical with the Mushmahhu) and Bashmu, whose constellation (despite having a single Head) was later associated by the Greeks with the Hydra.

She was decommissioned and sold to the Indonesian Navy in 1986 and renamed KRI "Dewa Kembar" (Pennant Number 932); she was still in service in 2006. There have been eight ships of the name in the Royal Navy, named for the Hydra of Greek Mythology, a serpent with many heads (though nine is generally accepted as standard), the centre one of which was immortal. The monster was overcome and slain by Hercules. The ship's badge of HMS "Hydra" depicts the monster with seven heads. The ship's motto was "Ut Herculis Perseverantia" ("Like Hercules Persevere").
