Valentin's sharpnose puffer is a small reef fish with four black stripes across its back. It lives in warm seas across the Indian Ocean, the Red Sea and parts of the Pacific. It is special because its skin holds one of the most potent natural poisons known, which keeps most predators away.1

Giftig deur 'n byt of steek, of giftig om aan te raak of te eet? Sommige diere spuit gif in met 'n byt of 'n steek. Ander is skadelik om aan te raak of te eet. Hierdie een is giftig om aan te raak of te eet.

Hoe om dit te herken

Four distinct black stripes, called saddles, run across its back.1
The head is blue-grey.1
The main body is white, speckled with blue-grey spots.1
The tail and fins show hints of yellow, and a rainbow streak sits behind the eyes.1

Word dikwels verwar met: The filefish Paraluteres prionurus has similar colours and sometimes swims in schools with this puffer. It mimics the puffer's appearance for protection, but it is not toxic.1

Gifkrag

Giftig om te eet

Dit is net skadelik as iets dit eet.

Wat doen sy gif as jy daaraan raak of dit eet?

Its skin and other tissues contain tetrodotoxin, a neurotoxin, which attacks the nerves. It is one of the most potent naturally occurring toxins and is lethal to many species of fish. This makes the fish unpalatable to predators.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: ErnstigAs iemand dit eet, moet hy dokter toe gaan. Sterftes is baie skaars.

It is highly poisonous to eat.1

Wat doen dit as dit bang is?

It gulps water to puff its body up to three or four times its normal volume, and its toxic skin deters predators.1

As iemand daaraan geraak of dit geëet het

As iemand dit geëet het of simptome kry nadat hy dit geëet het: bel dadelik jou noodnommer of 'n gifsentrum.

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 jy daaraan geraak of dit geëet het: moenie jou oë of mond vryf nie, was jou hande en kry mediese hulp.

Dit is nie uit om jou te kry nie. Sy gif is net daar sodat niks dit eet nie. Meer oor veilig bly

die moeite werd om te weet

Feite

Its tetrodotoxin is one of the most potent naturally occurring toxins, and it is lethal to many fish.1

A non-toxic filefish, Paraluteres prionurus, has evolved to look like this puffer, which helps it avoid predators.1

Its eggs are unpalatable, so predatory fish rarely eat them, and any swallowed eggs are quickly passed out again. This means the parents need not guard them.1

Juveniles of the grouper Plectropomus laevis also mimic its colours.1

Its eggs, at 0.68 to 0.72 mm across, are among the smallest in the puffer family Tetraodontidae.1

Mite-breker

Mite: Pufferfish hold their breath while they puff up.

Waarheid: A 2014 study found that oxygen consumption actually increases while the fish is inflated. Oxygen intake through the gills is almost five times higher than normal.1
