Also known as the Bull Rout or the Father Lasher, the Short-spined Sea Scorpion grows to about 30cms and spends most of its time stationary on the bottom. Its colour varies very significantly depending on what it is resting on and the surest way to distinguish it from its smaller relative the Long-spined Sea Scorpion, is to look at the corners of the mouth. The Long-spined always has a small barbel there whereas the Long-spined does not.
