Aquatic oozes that live near water, sea slimes are a very clear blue that makes them almost indistinguishable from the water they live in. They prey on fish and other marine life, but a hungry slime attacks passing ships and coastal settlements in an effort to find food, dissolving flesh, wood, and bone, but leaving metal and stone unharmed.
Ooze Nature. A sea slime doesn't require sleep.
