Red lionfish

Pterois volitans

Oor die naam: The common name "lionfish" comes from the fins, which create an appearance similar to a mane, and the scientific name volitans means "flying", probably because of the large pectoral fins that resemble wings.1

The red lionfish is a venomous coral reef fish with long, frilled fins that look like a mane. It is native to the Indo-Pacific, but it has spread into the Caribbean, the east coast of the United States and other areas, where it is an invasive species. Its spreading is a serious problem for local reef life.1

Tuis

It is a coral reef fish. The red lionfish was likely first introduced off the Florida coast in the early to mid-1980s, almost certainly from the aquarium trade.1

Wat eet dit?

It eats crustaceans such as shrimps and crabs, other invertebrates and small fish, including young lionfish. It corners prey with its large fins, then swallows the prey whole, mostly hunting from late afternoon to dawn.1

Hoe om dit te herken

White stripes alternate with red, maroon or brown stripes.1
Large venomous spines run along the back (dorsal) fin, with more on the pelvic and anal fins.1
Long, non-venomous fins create a mane-like outline.1
Adults can grow up to 47 cm long.1

Word dikwels verwar met: Pterois miles is a similar relative, and both species are invasive in the same areas.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 venomous spines are used purely for defence. A sting can cause extreme pain, and possibly headaches, vomiting and breathing difficulties.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: ErnstigAs sy stekels jou steek, gaan dokter toe. Sterftes is baie skaars.

Its sting is usually not fatal to humans. Some people are more sensitive to the venom than others, so the effects can be more serious for them.1

Wat doen dit as dit bang is?

When threatened, it turns its venomous dorsal spines towards the attacker, even if it has to swim upside down.1

As sy stekels jou steek

A common treatment is soaking the affected area in hot water, as very few hospitals carry specific treatments. Immediate emergency medical attention is strongly recommended, because some people react more strongly than others.1
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

About 93% of the invasive lionfish population is the red lionfish.1

It strikes at prey that comes within 9 cm of its mouth, drawing the prey in with a sudden rush of water.1

Lionfish reproduce monthly, which helps their numbers grow quickly in new areas.1

Lionfish larvae hatch 36 hours after fertilisation.1

The larval stage is the shortest part of its life, lasting about one month.1
