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

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

Sering dikelirukan dengan: 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

Kuasa racun

Racun di kulitnya

Kulitnya beracun. Ia berbahaya untuk disentuh, dijilat atau dimakan.

Apa kesan racunnya?

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

Berapa bahaya ia kepada manusia?

Bahaya kepada manusia: Sangat berbahayaIa boleh membunuh orang yang tidak mendapat rawatan.

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

Apa yang ia buat apabila takut?

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

Jika seseorang menyentuh atau memakannya

Jika seseorang menyentuhnya: basuh tangan dengan bersih dan jangan sentuh mata atau mulut. Jika kanak-kanak atau haiwan peliharaan menjilat atau memakannya: hubungi pusat racun atau nombor kecemasan.

Sentiasa hubungi nombor kecemasan dahulu (112, 000, 911). Ini panduan pertolongan cemas umum, bukan nasihat perubatan. Asas pertolongan cemas

Kekal selamat

Jangan sesekali sentuh, tangkap atau usik haiwan liar, walaupun yang kecil, dan walaupun ia nampak tidur atau mati.
Beri ia ruang. Jika kamu terjumpa, bertenang, undur perlahan-lahan dan biarkan ia pergi.
Jika kamu menyentuh atau memakannya: jangan gosok mata atau mulut, basuh tangan dan dapatkan bantuan perubatan.

Ia bukan mahu memburu kamu. Racunnya ada hanya supaya tiada apa yang memakannya. Lagi tentang keselamatan

berguna untuk diketahui

Fakta

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
