The California newt is a small amphibian with a warty grey back and a bright orange-yellow belly. It lives only in California, in the western United States. Its skin contains a powerful poison, so it is a good example of an animal you should look at but never handle.1

Cara mengenalinya

Warty, slate-grey skin on the back1
Bright orange-yellow skin on the underside1
Orange skin around the bottom of the eye (the rough-skinned newt has grey there)1
Eyes that stick out beyond the edge of the jaw when seen from above, giving the head a bullet-like shape1
Adults are about 13 to 20 cm long1

Sering dikelirukan dengan: The rough-skinned newt looks very similar and is often hard to tell apart in the field. The California newt has orange skin around the bottom of the eye and eyes that stick out past the jaw, while the rough-skinned newt has grey skin there and eyes that do not stick out. The red-bellied newt has dark irises instead of yellow, more red underneath, and a dark band across the vent.1

Kuasa racun

Racun di kulitnya

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

Apa kesan racunnya?

This animal is poisonous, not venomous, so it does not bite or sting. Its skin glands release tetrodotoxin, a neurotoxin (a poison that attacks the nerves). It is hundreds of times more toxic than cyanide and is the same toxin found in pufferfish and harlequin frogs. It is strong enough to kill most vertebrates, including humans.1

Berapa bahaya ia kepada manusia?

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

The toxin is strong enough to kill people. Because of their toxin, California newts have very few natural predators.1

Apa yang ia buat apabila takut?

When threatened, it performs the unken reflex: it stretches out, arches its body, and lifts its head and tail into the air to show its bright belly. It can also produce a foamy substance when exposed to high temperatures.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

Because snakes evolved resistance, newts have evolved to make far more toxin than any other predator could need, an evolutionary arms race.1

The foam the newt produces forms a protective layer that helps it keep moisture and shields it from burns during wildfires.1

Researchers believe bacteria make the tetrodotoxin, and the newts acquire it by eating those bacteria.1

Garter snakes are the most common predator, and some have developed resistance to the newt's toxin.1

Adults usually return to the same pool where they hatched to breed.1

Pemecah mitos

Mitos: Newts do not make any sounds.

Hakikat: California newts make clicks, squeaks and whistles. Clicks are the most common, squeaks are used in defence, and whistles seem to be linked to recognising sex and to social rank.1
