Rough-skinned newt
Gif in sy velGiftig om aan te raak of te eet, nie deur 'n byt of steek nieThe 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

Hoe om dit te herken
- 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
Word dikwels verwar met: 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
Gifkrag
Sy vel is giftig. Dit is gevaarlik om aan te raak, te lek of te eet.
Wat doen sy gif as jy daaraan raak of dit eet?
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
Hoe gevaarlik is dit vir mense?
Gevaar vir mense: Baie gevaarlikDit kan 'n mens doodmaak wat geen behandeling kry nie.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
Wat doen dit as dit bang is?
It gives off an acrid smell that warns animals to stay away.1
As iemand daaraan geraak of dit geëet het
- As iemand aan een geraak het: was die hande goed en moenie aan die oë of mond raak nie. As 'n kind of troeteldier een gelek of geëet het: bel 'n gifsentrum of jou noodnommer.
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

Feite
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
