This fish belongs to the family Scorpaenidae and its common name is Scorpion fish.
It has a brownish or reddish gray coloration and dark stains. It inhabits rocky sea floors and are therefore also called stone fish. They occur in areas with grassy sea floors and in summer they can be found in very shallow waters.
They are carnivorous and are difficult to identify because of their anatomical characteristics and their capacity for mimicry.
Normally they can be seen swimming calmly in rocky areas but when stepped upon they cause several puncture wounds with their dorsal thorns, which release a toxic substance. The thorn wounds cause a strong pain, often followed by an inflammation, fever, difficultly walking and other symptoms.
Once out of the water, the first measure to take is to submerge the part affected in hot water (as hot as you can support) for 30 to 90 minutes, and then to go to the nearest medical center to receive treatment consisting of pain killers, antibiotics, and an anti-tetanus injection, if necessary; etc.
For this reason we recommend
that if you plan to enter the water in rocky areas, protect your feet
with appropriate footwear.
