The marbled spinefoot is a shoaling fish that mostly eats algae. It lives in shallow warm seas in the Red Sea and western Indian Ocean, and it has spread into the Mediterranean. Its spines carry venom, so it is one to leave alone.1

Strupene bodice

Ostre bodice nosijo strup. Če stopiš nanjo ali jo primeš, boli.

Kaj naredi njen strup, ko ugrizne ali piči?

The spines in the fins have venom glands at their base. The venom is a protein that is damaged by heat. The sting is very painful.1

Kako nevarna je za ljudi?

The spines can inflict a painful sting if the fish is handled incorrectly. No deaths from its venom have been recorded. Separately, poisoning has been recorded in Israel after people ate its flesh, linked to fish caught in polluted water.1

Kaj naredi, ko se prestraši?

Its spines are barbed and venomous, and they can injure anyone who handles the fish carelessly.1

Če te zbode z bodicami

The affected area should be treated with as high a temperature as possible, within 43 to 46 °C, because heat damages the venom. The person should also be checked for possible infection.1
Rano daj v vročo vodo, tako vročo, kot jo poškodovanec prenese, ne da bi se opekel (preizkusi jo s svojo roko), za 30 do 90 minut. Poišči zdravniško pomoč, še posebej pri kamnitih ribah in morskih bičih.

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te zbode z bodicami: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

Some people have reported hallucinations after eating it.1

Eating its flesh has caused poisoning, and the toxins involved are similar to ciguatoxin.1

Adults can eat jellyfish, including comb jellies and moon jellyfish, in parts of the northern Red Sea.1

It reached the Mediterranean through the Suez Canal, first recorded off Palestine in 1927.1

It can be bred in captivity and is being studied as a farmed fish because it eats plant-based feed.1
