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

Ho e tseba jwang

  • 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

Hangata e ferekanngwa le: 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

Matla a chefo

E a chefa ha e jewa

Chefo ya yona (e chefang ha o e ama kapa o e ja) e etsang?

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

E kotsi hakae ho batho?

Kotsi ho batho: E tebilengHaeba motho a e ja, eya ho ngaka. Lefu le etsahala ka seoelo haholo.

It is highly poisonous to eat.1

E etsang ha e tshohile?

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

Dintlha

1

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

2

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

3

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

4

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

5

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

Ho senya ditshomo

Tshomo: Pufferfish hold their breath while they puff up.

Nnete: 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
