The rough-skinned newt is a small, stocky amphibian from the Pacific Northwest of North America. Its skin gives off one of the strongest toxins of any newt, so it is a creature to admire from a distance and never handle. Its toxin is also linked to a famous fight between newts and garter snakes.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

Pacific Northwest of North America, from Alaska south to Santa Cruz, California. Rare east of the Cascade Mountains.1

Amerika Kaskazini

Nyumbani

Jinsi ya kumtambua

Stocky body with a rounded snout.1
Top ranges from light brown to olive or brownish-black.1
Underside, including the head, legs and tail, is orange to yellow.1
Skin is granular, but males are smooth-skinned during the breeding season.1
Adults are 11 to 18 cm long overall, including the tail.1

Mara nyingi huchanganywa na: The California newt (Taricha torosa) looks similar. The rough-skinned newt has smaller eyes, yellow irises, V-shaped tooth patterns and uniformly dark eyelids. During breeding season, males have large swollen vent lobes and cornified toe pads, which separate them from females.1

Nguvu ya sumu

Sumu ndani ya ngozi

Ngozi yake ina sumu. Ni hatari kumgusa, kumramba au kumla.

Sumu yake hufanya nini?

This animal is poisonous rather than venomous, so it does not bite or sting. Its skin produces tetrodotoxin (TTX), a neurotoxin that attacks the nerves. It blocks the sodium channels that nerves need to send signals. This can cause paralysis and death by asphyxiation, which means the person cannot breathe.1

The toxin is mainly dangerous if the newt is eaten. Some people have had skin irritation after handling the newt, especially if they touch their eyes without washing their hands first. In 1979, a 29-year-old man from Oregon died after eating one. Some newts make enough toxin to kill several adult humans.1

Hufanya nini akiogopa?

It gives off an acrid smell that warns animals to stay away.1

Mtu akimgusa au kumla

Mtu akimgusa: nawa mikono vizuri na usiguse macho wala mdomo. Mtoto au mnyama kipenzi akimramba au kumla: piga kituo cha taarifa za sumu au namba ya dharura.

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

Ukweli

Some common garter snakes can eat rough-skinned newts and survive. They are the only known animals today able to do this.1

A garter snake tests a newt's toxin level by partly swallowing it, then either swallows it fully or lets it go.1

Newts can detect the chemical signature of a snake that has digested one of their kind, and they move away from it.1

The toxin is made by the newt's skin microbiome, meaning the bacteria living on its skin.1

The newt and the garter snake are an example of an evolutionary arms race. Each change in one species drives change in the other.1

The toxin also appears in pufferfish and other marine animals, which share the same nerve-blocking effect.1
