Beware of the Lionfish's venomous dorsal spines!
Zebra Lionfish Dendrochirus zebra are especilly photogenic however be warned, they may not always be in a cooperative mood for photographers to take advantage of. This was my very first Zebra Lionfish image taken in July 1969.
All scorpionfish are armed with venomous dorsal, ventral and anal spines and some also have venomous head and cheek spines. All produce painful stings lasting up to and sometimes beyond six hours. In most species the venom isn't injected (like the stonefish) but lies inside the spines integument sheath and only enters the wound as a dissolvent protein, the venom is denatured by heat and is water soluble.
Common Lionfish Pterois volitans. Many underwater photographers have been stung trying to manipulate the fish into a more visually orientated aspect. Like all Lionfish, it’s a 6-hour ordeal, if stung. Don’t play with Lionfish!
Found in the Indo-Pacific, this species grows to 38 cm (15 in) and inhabits coral reefs, rubble and sandy, mud bottoms; it also occurs around rocky reefs and in bays and estuaries.
The Common Lionfish has very long, venomous dorsal spines with large dark spots on the rear flaps. The broad, filamentous pectoral fin rays are long and feather-like and the rear dorsal fin, anal fin and tail have black spots.
This diver’s knuckle was spined when she was playing with the Fish, rounding it up for her husband so as he could take a picture. However, the Lionfish had other ideas, put its head down and spined her hand.
SYMPTOMS:
Pain is immediate and intense causing noticeable distress, but not as severe as stonefish or ghouls. Many species are quite small (fortesque) but still pack a virulent sting, often resulting in localised paralysis. Respiratory problems may occur in serious cases.
FIRST AID MANAGEMENT:
Rescue casualty
Reassure the casualty
Reduce shock
Lie casualty down with affected part in an elevated position
Immersion in hot water (non-scalding) will alleviate pain. Add heat as water cools
Induced bleeding may help to irrigate venom from wound
Any puncture wound must be investigated by medical personnel as tips of spines, spine sheath or other debris may be still in the wound and if not removed can cause serious infections
Seek urgent Emergency Service Assistance
Post-wound neuropsychological effects may arise. Casualty may be advised to take notice of possible anxiety, insomnia or depression symptoms.
