The California scorpionfish is a spiny fish that lives on the ocean floor along the Pacific coast of California and Baja California. It stays still among rocks and in caves, where its spotted colours help it blend in. Its spines carry venom, so it is one to leave alone.1

Leef in

Eastern Pacific Ocean: from Santa Cruz, California, south along Baja California, and in the Gulf of California1

Stille Oseaan, Golf van Kalifornië

Tuis

It lives on rocky bottoms just offshore or in bays, and it also uses underwater caves. It is usually found in water up to about 30 metres deep, though it can go down to 183 metres. People most often meet it when fishing, when it is pulled from the hook.1

Lengte

43 cm tot 47 cm (1,4 ft tot 1,5 ft)1

Topspoed

omtrent 2 km/h (1,2 mph)

Swem, rowwe skatting

Wat eet dit?

It eats other fish, crustaceans, octopuses and squid. Juvenile crabs are its favourite prey, especially in autumn and winter.1

Gifkrag

Giftige stekels

Skerp stekels dra die gif. Dit maak seer as jy daarop trap of dit gryp.

Wat doen sy gif as dit byt of steek?

Its spines contain venom-producing glands. The venom is cardiotoxic, meaning it affects the heart; in laboratory studies it caused changes in blood pressure and heart rhythm. A spine prick can cause severe, throbbing pain, swelling, numbness and discolouration of the finger, with pain spreading up the arm. Nausea, faintness and pale, clammy skin can also occur.1

Hoe gevaarlik is dit vir mense?

It has been responsible for many human injuries and has been called one of the most noxious marine animals in California waters. Fishermen are most often affected when removing the fish from a hook. The effects can feel much like a rattlesnake bite, and one victim developed pericarditis, an inflammation of the lining around the heart. In one reported case, the victim recovered in about two weeks.1

Wat doen dit as dit bang is?

When pulled from the water, it flares the spines on its fins and gill covers, which makes it difficult to handle.1

As sy stekels jou steek

Sit die wond in warm water, so warm as wat die persoon kan verdra sonder om te brand (toets dit met jou eie hand), vir 30 tot 90 minute. Kry mediese hulp, veral vir klipvisse en pylsterte.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As sy stekels jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

Its venom is produced in grooves along each spine, and the spine is covered by a thin membrane that is pushed back as it enters the skin, helping to inject the venom.1

It has no swim bladder, which is why it spends most of its time resting on the ocean floor.1

Some individuals have travelled up to 200 km in mark and recapture studies. One fish moved from near Santa Cruz Island to Long Beach over about 14 months.1

The California two-spot octopus preys on it, and the fish will also eat small octopuses of the same kind.1

Its maximum recorded lifespan is 21 years.1

Despite its danger, it is considered a very good food fish once the spines have been avoided, and it is sought after by some Asian communities in Southern California.1
