Black scorpionfish - Scorpaena porcus
In this video
Black scorpionfish, Scorpaena porcus, is a “coveted prey” by underwater photographers and in the video we see why. It is one of the most poisonous fish in the Mediterranean Sea together with the all Scorpaenidae and the Weeverfish. Scorfano Nero Black scorpionfish Scorpaena Porcus intotheblue.it
Like all fish belonging to the Scorpaenidae family, even the black scorpionfish has venom glands placed under the spines of the dorsal and anal fins. Aware of its dangerousness and phenomenal ability to blend in between the rocks, this fish gets very close, in the movie you can see that I practically approached with the camera until it almost touched it, and remained motionless for a few minutes (probably also confused and dazzled by the light) but, as soon as the safety distance was exceeded, he moved a few centimeters away arching the poisonous spines to defend himself.
Bites are almost always accidental (especially among fishermen and divers) and occur because the divers do not notice the presence of the Scorpionfish completely camouflaged with the environment. The punctures are therefore quite frequent and in these cases a strong pain occurs, sometimes with the appearance of nausea, vomiting and shock. The symptomatic treatment consists in immersing the wound in hot water, since the toxin is thermolabile. However, an antibiotic treatment is recommended (sometimes the wound can go into necrosis) and tetanus. Scorfano Nero Black scorpionfish Scorpaena Porcus intotheblue.it
Immobility and camouflage as well as a defense are also the main hunting strategy. The Scorpionfish in fact feeds on crustaceans, invertebrates and small fish (Gobiidi, Blennidi), which it captures with a rapid movement of the protractile mouth. It awaits its immobile prey, perfectly camouflaged with the surrounding environment.
