Notes:

According to Tammas, the nuckelavee has a man's torso attached to a horse's back as if it were a rider. The male torso has no legs, but its arms can reach the ground from its position on top of the equine body, the legs of which have fin like appendages. The torso has a large head – possibly as much as 3 feet (90 centimetres) in diameter – that rolls back and forth. The monster described by Tammas has two heads; the equine head has an enormous gaping mouth that exudes a smelly toxic vapour, and a single giant eye like a burning red flame. A particularly gruesome detail is that the nuckelavee has no skin; black blood courses through yellow veins, and the pale sinews and powerful muscles are visible as a pulsating mass. Other reports state that the creature resembles a centaur.
