Dunsteos

Dunsteos are gigantic salt-water fish. They can grow up to 10 meters in length, and are covered in thick, bony plates. The bite of a dunsteo is so strong that it can cut through up to 22 cm of iron plating. They mostly live in cold, nothern seas, but have been found as far south as the coast of Evandar. Dunsteos are highly aggressive, and reports of them attacking ships are not uncommon. The plates that act as teeth are very valuable, their extremely high density makes them excellent for use as shields and plate armour. As such, brave (and foolish) people attempt to hunt dunsteos by luring them into shallow water and pouring poison on them. Since dunsteos are very large, it takes large quantities of most poisons to kill them, so many of those who hunt them use relatively cheap poisons. Obviously, hunting these monstrous fish is incredibly dangerous, so it is not surprising that it is considered to be the deadliest profession. Even though an experienced crew might only kill 4 or 5 per year, it is enough to make them rich.
