The Iberian ribbed newt is a salamander that lives in ponds and wells in Spain, Portugal and northern Morocco. It is the largest European newt species. When threatened, it can push its sharp ribs out through its skin, which gives it a way to defend itself against predators.1

Pozoi-ahalmena

Arantza pozoitsuak

Arantza zorrotzek daramate pozoia. Zapaltzeak edo heltzeak min ematen du.

Zer egiten du bere pozoiak?

When threatened, the newt releases a milky, thick poison from glands on its neck, back, sides and tail as its ribs push out. The poison coats the ribs, which can pierce the skin of a predator's mouth and inject toxins.1

Zein arriskutsua da pertsonentzat?

Arriskua pertsonentzat: ArinaErle-ziztada bat bezala edo gutxiago. Ia kaltegabea pertsonentzat.

The rib defence is completely harmless to humans. The ribs cause only little harm to the newt itself, and its skin quickly heals without infection.1

Zer egiten du beldurtzen denean?

It tries to run away from predators first. If it cannot escape, it pushes its sharp ribs through its sides and releases poison.1

Bere arantzek zulatzen bazaituzte

Norbaitek bat ukitu badu: garbitu eskuak ondo eta ez ukitu begiak edo ahoa. Haur edo maskota batek bat miazkatu edo jan badu: deitu zure intoxikazio-zentrora edo larrialdi-zenbakira.

Deitu beti lehenik zure larrialdi-zenbakira (112, 000, 911). Lehen sorospenei buruzko orientabide orokorra da hau, ez mediku-aholkua. Lehen sorospenen oinarriak

Egon seguru

Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
Bere arantzek zulatzen bazaituzte: egon lasai, egon geldi, deitu zure larrialdi-zenbakira (112, 000, 911) edo joan ospitalera azkar. Gogoratu nolakoa zen, argazki batek laguntzen du.

Ez dabil zure atzetik. Pozoia janaria harrapatzeko edo bere burua babesteko erabiltzen du, eta askoz nahiago du ezkutatu. Seguru egoteari buruz gehiago

Datuak

Its ribs can push through its skin to act as a defence, a primitive and rudimentary form of envenomation.1

It is a model animal for regeneration research. It can regrow lost limbs, injured heart tissue, brain cells, eye lenses and parts of its spinal cord.1

This newt has been sent into space on at least six missions, starting in 1985.1

In genetic males and females, temperature can override sex chromosomes. Some ZW larvae reared at 32 °C (90 °F) become functional males.1

Its immune system, rib-coated collagen and antimicrobial peptides let the pierced skin heal quickly without infection.1

Females can keep live sperm in their cloaca for up to five months.1

Mito-hauslea

Mitoa: The newt's ribs and poison are dangerous to people.

Egia: The ribs and poison are a defence against predators. The rib defence is completely harmless to humans.1
