also known as the Spotless Lionfish or the One-Spot Lionfish, is a species of marine fish belonging to the family Scorpaenidae. It is native to the Indo-Pacific region and can be found in shallow waters, coral reefs, and lagoons.

The Devil Lionfish has a distinctive appearance, with elongated, spiky pectoral fins that give it a menacing appearance. It has a round, flat body that can reach up to 38 centimeters in length, with a large mouth and eyes. The body is generally tan or brown in color, with darker markings on the fins and body that give it a mottled appearance. Unlike other lionfish species, the Devil Lionfish has a single, large black spot on its dorsal fin.

In terms of social behavior, Devil Lionfish are solitary creatures and are usually found alone or in pairs. They are carnivorous and feed on a variety of small fish, crustaceans, and other invertebrates. Their venomous spines and camouflage make them effective predators, and they are known to be opportunistic feeders, preying on whatever is available in their environment.

While Devil Lionfish are not known for their fashion or aesthetic qualities, they are a popular species in the aquarium trade due to their unique appearance and relative ease of care. However, it is important to note that they are an invasive species in some parts of the world, including the Caribbean, where they have been introduced through the aquarium trade. In these regions, Devil Lionfish have become a significant threat to native fish populations and ecosystems.

In terms of conservation status, the Devil Lionfish is not currently listed as threatened or endangered. However, it is important to take steps to prevent their introduction to new environments and to manage populations where they have already become established. This can include measures such as culling programs or the promotion of lionfish as a food source in regions where they are invasive. Overall, the Devil Lionfish is an interesting and unique species with a distinct appearance and important ecological considerations.
