The Black Demon (Spanish: El Demonio Negro) is said to be an enormous black shark off the coast of Mexico's Baja California peninsula. In recent times, local fishermen report seeing the black monstrosity. The Black Demon is said to be 20-60 feet long and weighing anywhere between 50-100,000 lbs! It is said to resemble a great white, but with very dark coloration and a truly monstrous tail.
Some say it could be the Megalodon or a new species of shark, maybe even an over sized Great White. Many expeditions were launched to locate this monstrous creature, even on MonsterQuest in the chapter Mega-Jaws, but they didn't discover anything. Sadly, sightings are rare and the creature is elusive. Because of this, not much is known. It is possible since albinism is found in sharks that melanism could be too.
- Canadian Albino Shark, another similar cryptid.
- Megalodon, prehistoric giant shark that could still survive.
