40d:Sea lamprey

Sea lamprey is a parasitic lamprey (species of fish that has a oval mouth and no jawbone), that will attach itself on a fish (or whale, etc.), bite a hole in its skin and suck blood. They are eqvivalent of mosquitos in water. In real world they do not attach themselves in anything that will rise above water for long periods of time (ie. anything with something over their skin, like fur or feathers) but in the game they will sometimes attack anything that comes near them, like an occasional dwarf.
