What Makes Scorpionfish Special?
Hidden Weapons
Scorpionfish have venomous spines along their back for defence. Unlike Lionfish, they don't advertise these weapons with spectacular fins, they rely on being almost invisible.
Dangerous, but Not Aggressive
Despite their fearsome appearance, Scorpionfish are not aggressive towards people. The danger comes mainly from accidentally touching or stepping on one.
Scorpionfish or Stonefish?
Good to know: Caribbean Scorpionfish are sometimes confused with Stonefish, which are much more venomous, but true stonefish do not naturally occur in the Caribbean.
Can You Spot It?
Camouflage is their greatest weapon. Their mottled colours, irregular shape and small skin flaps make them look remarkably like rocks, coral or algae. They can remain completely motionless for long periods, waiting for an unsuspecting fish or shrimp to come within striking distance.
Gone in a Split Second
When prey gets close, the Scorpionfish suddenly opens its large mouth and creates powerful suction, swallowing its prey in a fraction of a second.
A Hidden Flash of Colour
When resting on the reef, a Spotted Scorpionfish may look like little more than a lumpy rock. But when it starts to move, it reveals a surprise: large, beautifully patterned pectoral fins hidden along the sides of its body.
As it swims, these fins spread out like fans, showing striking dark markings with pale or white spots. Once the fish settles again, the fins fold away and almost completely disappear from view.
