Valentin's sharpnose puffer
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

Nola ezagutu
- 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
Askotan honekin nahasten da: 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
Pozoi-indarra
Zerbaitek jaten badu bakarrik da kaltegarria.
Zer egiten du bere toxinak?
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

Arriskua pertsonentzat: LarriaNorbaitek jaten badu, joan medikuarengana. Heriotzak oso arraroak dira.It is highly poisonous to eat.1
Zer egiten du beldurtzen denean?
It gulps water to puff its body up to three or four times its normal volume, and its toxic skin deters predators.1
Norbaitek ukitu edo jan badu
- Norbaitek jan badu edo jan ondoren sintomak baditu: deitu berehala zure larrialdi-zenbakira edo intoxikazio-zentrora.
Deitu beti lehenik zure larrialdi-zenbakira (112, 000, 911). Lehen sorospenei buruzko orientabide orokorra da hau, ez mediku-aholkua. Lehen sorospenen oinarriak
Egon seguru
- Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
- Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
- Ukitu edo jan baduzu: ez igurtzi begiak edo ahoa, garbitu eskuak eta lortu mediku-laguntza.
Ez dabil zure atzetik. Pozoia ezerk jan ez dezan baino ez du. Seguru egoteari buruz gehiago

Datuak
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
Mito-hauslea
Mitoa: Pufferfish hold their breath while they puff up.
Egia: 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
