Wreathed Choker These worms are approx. 2 meters long and usually they are rather indifferent. They will only attack when someone comes too close. However, when they attack they are very dangerous opponents. Sturdy scales protect their snake-like bodies which allow them to move swiftly in water. A pair of rudimentary arms hangs from their body and they use these arms as a rudder while swimming. The Wreathed Choker’s main weapons are its teeth. Its head snaps forward as it bites. There are two sizes of Wreathed Chokers.
