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

Ahabanza
California newts live in woodlands and chaparral near the small ponds and creeks where they breed. During the day they hide under rocks, logs or leaf litter. They travel to ponds, streams and slow-moving water to breed, especially during the wet season.1

Uko wayimenya

  • 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

Ikunze kwitiranywa na: 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

Imbaraga z'uburozi

Uburozi mu ruhu rwayo

Uruhu rwayo rufite uburozi. Ni bibi kuyikoraho, kuyirigata cyangwa kuyirya.

Uburozi bwayo bukora iki?

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

Iteje akaga kangana iki ku bantu?

Akaga ku bantu: Iteje akaga cyaneIshobora kwica umuntu utavuwe.

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

Ikora iki iyo ifite ubwoba?

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

Niba hari uwayikozeho cyangwa uwayiriye

  • Niba hari uwakoze ku yindi: karaba intoki neza kandi ntukore ku maso cyangwa ku munwa. Niba umwana cyangwa itungo ryayirigase cyangwa ryayiriye: hamagara ikigo gishinzwe uburozi cyangwa nimero y'ubutabazi.

Buri gihe banza uhamagare nimero y'ubutabazi (112, 000, 911). Izi ni inama rusange z'ubutabazi bw'ibanze, si inama za muganga. Ibanze by'ubutabazi bw'ibanze

Irinde akaga

  • Ntuzigere ukora, ufata cyangwa ushotora inyamaswa yo mu gasozi, nubwo yaba ntoya, kandi nubwo yasa n'isinziriye cyangwa yapfuye.
  • Yihe umwanya. Niba uhuye n'imwe, tuza, usubire inyuma buhoro buhoro kandi uyireke yigendere.
  • Niba wayikozeho cyangwa wayiriye: ntukube amaso cyangwa umunwa, karaba intoki kandi ushake ubufasha bwa muganga.

Ntigushakisha ngo ikugirire nabi. Uburozi bwayo buriho gusa kugira ngo hatagira ikiyirya. Ibindi ku kwirinda

Ibintu by'ukuri

1

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

2

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

3

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

4

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

5

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

Usenya ibinyoma

Ikinyoma: Newts do not make any sounds.

Ukuri: 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
