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

Anadunga sumu au ana sumu ya kugusa? Wanyama wanaodunga sumu huingiza sumu kwa kuuma au kudunga. Wanyama wenye sumu ya kugusa au kula hudhuru wakiguswa au kuliwa. Huyu ni wa aina ya pili.

Anaishi

Tropical and subtropical waters of the Indian Ocean, including the Red Sea, and east to the oceanic islands of the Pacific Ocean.1

Jinsi ya kumtambua

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

Mara nyingi huchanganywa na: 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

Nguvu ya sumu

Sumu akiliwa

Ni hatari tu kitu kikimla.

Sumu yake hufanya nini?

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

Ana hatari gani kwa watu?

Hatari kwa watu: MbayaMtu akimla, aende kwa daktari. Vifo ni nadra sana.

It is highly poisonous to eat.1

Hufanya nini akiogopa?

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

Mtu akimgusa au kumla

Mtu akimla au akipata dalili baada ya kumla: piga namba ya dharura au kituo cha taarifa za sumu mara moja.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Ukimgusa au kumla: usisugue macho wala mdomo, nawa mikono na utafute msaada wa kitabibu.

Hakuwindi wewe. Sumu yake ipo tu ili asiliwe na yeyote. Zaidi kuhusu kukaa salama

inafaa kujua

Ukweli

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

Kuvunja dhana potofu

Dhana potofu: Pufferfish hold their breath while they puff up.

Ukweli: 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
