Scorpion fish facts - pictures-of scorpion fish- datos sobre el pez escorpión

An interesting fact about the scorpion fish is that you don’t see it.

Usually, when we write an article about a Caribbean marine animal, we make reference to the times we see them or accompany us on our dives.

Well, we barely see the scorpion fish. This is not because its number of specimens is low or it is among the threatened species, no. The scorpion fish goes unnoticed because it is a master of disguise, an expert in camouflage, and an ace of concealment.

Therefore, adjust your glasses and look at the table of contents. So, you don’t miss out.

3. Scorpionfish Vs Lion Fish Vs Stone Fish

Scorpionfish, lionfish, and stonefish are three types of fish or the Scorpaenidae family. Due to the similarity of the scientific name with the word scorpion, they are all popularly called scorpion fish.

 5. Are Scorpionfish poisonous?

All species in the scorpion fish family are considered venomous.

  • Scorpion Fish Venom

Most scorpionfish venom is found on the spines of their dorsal fins, although some species also have venom on their ventral and anal fins spines.

  • Scorpion Fish Sting.

The scorpion fish is not aggressive and does not attack humans. Nor does it run away. The sting occurs when the thorn breaks through the skin when touched.

6. Scorpionfish Predators

7. What Does the Scorpion Fish Eat?

Scorpionfish are mostly ambush hunters.

They feed on crustaceans, fish, and snails mainly. Even small cephalopods are part of their menu.

8. Scorpionfish Camouflage

The scorpion fish is heavily camouflaged and blends in with the environment, which helps them capture their prey. They mostly eat animals that eat plants or coral and confuse them with them. Other times, their victims seek safe refuge in the coral without knowing that they are nearing their end.

As we have seen, there are different species of scorpionfish. Some are better disguised among the mud and stones, while others are practically imperceptible among the corals.


9. Scorpionfish Reproduction

Although scorpion fish lead solitary lives, they do come together for reproduction.

The vast majority of species are ovoviviparous. This means that the eggs are fertilized inside the female. After that, she expels a gelatinous bag full of eggs. So, the current carries them away.

There are also pure oviparous species where the females spawn, while the males fertilize and incubate.

The hatched larvae live on plankton.
