Scorpion Fish Classification and Scientific Name

The Scorpion fishes go by the scientific name Scorpaenidae and belong to the kingdom Animalia and Phylum Chordata. They come from the class and order Actinopterygii and Scorpaeniformes respectively. There are about 100 to 200 subspecies and types of the Scorpionfish.

The scientific name Scorpaenidae comes from New Latin, combining Scorpaena and the suffix -idae. Scorpaena can be traced back to the Ancient Greek σκόρπαινα, which comes from the Greek word for scorpion. Interestingly, the Greek word for Scorpion is rooted in the Proto-Indo-European verb (s)ker, which means “to cut.”

Scorpion Fish Species

Scorpion fishes make up one of the largest marine families and consist of 100 to 200 different fish family members. Some of the more popular species include the lionfish, firefish, turkey fish, and stingfish, which are broken down into multiple types within their own families.

Presently, there are a total of 10 subfamilies, though 338 species fall into these categories, according to reports in 2018. However, the total amount will vary, based on where you get your information.

Scorpion Fish vs. Stonefish

Scorpion fishes have longer bodies while stone fishes have more of a round body shape. Meanwhile, the scorpionfishes have eyes that protrude, and the stone fishes have eyes that dig deeper down into their skulls. Another difference between the scorpionfish and the stonefish is that the former has a forward sitting jaw while the latter has a more upturned, grumpier looking one.

Scorpion Fish Appearance

Scorpion fishes have long bodies that are covered in feather-laden fins. They have skin flaps that also help them easily camouflaging and blend in with their surroundings.

Some scorpionfishes are brown or yellow, while others exhibit bright colors like red or orange. They are known to become almost invisible when they are near reefs and rocks.

The size of the scorpionfish is about 8 inches to 12 inches, and it weighs around 3.4 pounds.

They are usually motionless while near algae or rocks and also have venomous spines that are sharp and are covered in poisonous mucous.

Scorpion Fish Distribution, Population, and Habitat

The scorpionfishes are usually found in the Indo-Pacific regions and also inhibit the tropical underwater of the Indian ocean. Apart from that, these fishes are also found in the central and western parts of the Pacific Ocean and also in several parts of Indonesia.

These fishes usually exist where there are plenty of coral reefs and the temperature of the water is temperate. This is because the right temperatures help them survive better and the coral reefs help these fishes hide from predators efficiently.

The population of the scorpionfish is not known. However, fishes belonging to these families do exist in large numbers as more than 200 fishes are part of this family. They are, however, ‘not extinct’ as listed by the NOAA.

Scorpion Fish Predators and Prey

Even though the scorpionfishes are themselves poisonous and dangerous, they still fall prey to some of the sea creatures including large snappers, rays, and sharks. With so few predators, the scorpionfish can thrive greatly when it releases thousands of eggs to be fertilized. Still, this fish is dominant in its own right, so the predators that come after it must be equally threatening.

Meanwhile, they also feed on certain creatures including small fishes and snails. They also feed on crustaceans and coral reefs. Humans can become a victim of their sting, which will require immediate medical attention. While waiting for emergency services, the wound needs to be cleaned with the hottest water that the skin can handle for at least 30 minutes.

Scorpion Fish Reproduction and Lifespan

These fishes are oviparous. The female scorpionfishes often produce transparent or greenish eggs.

The eggs, as well as the sperms from the female and male scorpionfishes respectively, are released in the water and stay afloat near the surface of the water, where they are later attached.

However, other than that, not much is known about the mating process of these fishes. The lifespan of these fishes is usually about 15 years.

Scorpion Fish in Fishing and Cooking

Even though these fishes are not commonly caught because of the venom they carry around, some people do fish them out and also cook them. Scorpionfishes are safe to consume and are also a world-famous delicacy. Scorpionfish chips are very famous, and most people compare the flavor to a combination of sea bass and monkfish.

The easiest place to fish for them is in the South Pacific Ocean since they are commonly found in coral reefs. Still, fishers should be careful while fishing around these reefs so that they don’t destroy the local environment.
There is no shortage of recipes online for scorpionfish, depending on the species that is prepared. Due to their lack of meat, the cooking process doesn’t take long, and most dishes are ready within a matter of 10 minutes or less. When cooked properly, it doesn’t quite have the flakiness that some other fish do, but it is also incredibly tender.

Their thin meat absorbs other flavors well, much like any other crustacean. For anyone looking to prepare scorpionfish at home, they will want to stock up on some butter and spices, regardless of the recipe chosen.

To get the maximum flavor, try out the pan-roasted method seen here.
