What at first appeared to be multiple snakes tangled up with each other is in fact a multi-headed best, all of them connected to one large serpent body.

Hydras are reptile-like monsters with nine heads. A hydra is gray brown to dark brown, with a light yellow or tan underbelly. The eyes are amber, and the teeth are yellow-white. It is about 20 feet long and weighs about 4,000 pounds.

Deadly by Nature. Hydras are extremely poisonous, such that their blood is used in arrows to slay even more fearsome opponents. Their breath is dire enough to kill a man where he stands, but even the miasma that surrounds them can poison attackers even while the hydra sleeps.

Large, dragon-like creatures with multiple, serpentine heads. Sea hydras (adapted to water, with fins) also exist.
