Sea Serpents are a type of aquatic monsters.
Sea Serpents – Giant water snakes. Their scales are tough as steel, and larger examples can wrap themselves around a warship and crack it like an egg. They are particularly nasty in clutches where they can attack by the dozens. They’re like…snakes. In the water. Look, that’s all you need to know. Oh, and some of them can do nasty things like spit venom. Or shoot lightning. Like snakes.
On average Sea Serpents are twice the length of a warship, but some of their kind can be even bigger.
