The sea serpent is an aquatic creature found in several seas around the world including the Atlantic, Pacific, and Mediterranean Sea. Reaching over a hundred feet long with a horse-like head and snake-like body, the sea serpent is a fearsome looking creature. Despite this, no Sea Serpent has ever been known to hurt a human, despite Muggle stories of encounters with the beasts. It rises in humps out of the water as it swims.
