The perentie is one of the largest lizards alive, and the largest in Australia. It lives in the dry deserts of the west, centre and north of the country, where it is rarely seen. It is a powerful hunter that eats a wide range of animals, and it is important in many Aboriginal cultures.1

Inicio
Perenties live in rocky outcrops and gorges with hard-packed soil and loose stones. They are shy and usually avoid people, so they are rarely seen, especially as much of their range is remote.1

Que come?
Perenties are active hunters that mostly eat reptiles, small mammals and sometimes birds. They also scavenge carrion, and adults can kill kangaroos, using their powerful forelimbs and claws to tear off pieces too large to swallow whole.1

Como recoñecelo

  • Head and neck are creamy-white with a net-like (reticulated) pattern of black lines and flecks.1
  • Body is yellow or cream, with brown rosette markings on the back.1
  • Limbs are dark with white spots.1
  • Very lean for a large monitor, so much less bulky than a rock monitor of similar length.1

Adoita confundirse con: Rock monitors can reach a similar length, but they are much bulkier. Perenties are very lean for their size.1

Poder da pezoña

Morde

A pezoña sae polos seus cairos ou dentes cando morde.

Que fai a súa pezoña?

Researchers at the University of Melbourne found in 2005 that monitors may be somewhat venomous, which means they inject mild venom with a bite. A perentie bite can cause swelling within minutes, localised disruption of blood clotting (the blood's ability to clot is affected in the area), and shooting pain up to the elbow that can last several hours.1

Que perigoso é para as persoas?

Perigo para as persoas: DolorosoPode doer moito, pero case nunca é grave.

The bite can do much damage, not only from the teeth but also from the oral secretions.1

Que fai cando ten medo?

If threatened, a perentie will usually freeze flat on the ground or run away. If cornered, it stands its ground, inflates its throat, hisses, strikes with its tail, and may lunge with its mouth open.1

Se morde

  • Lava a ferida, mantén a persoa tranquila e busca axuda médica.

Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos

Mantente a salvo

  • Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
  • Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
  • Se un te morde: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos

1

Perenties eat other monitor lizards, including a 2 m perentie that was seen killing and eating a 1.5 m one.1

2

They often stand on their back legs and tail to get a better view, a behaviour called "tripoding".1

3

Perenties are among the largest living lizards, after the Komodo dragon, Asian water monitor and crocodile monitor.1

4

Perenties can dig a burrow for shelter in only minutes.1

5

The species was first named the "gigantic water lizard", even though it lives in dry desert country.1

6

The perentie has long been important to desert Aboriginal peoples, who ate it as food and used its fat for medicinal and ceremonial purposes.1

Desmontamitos

Mito: Monitor lizard bites were thought to cause problems only because of infection from bacteria in the animal's mouth.

Verdade: Researchers showed that the immediate effects of monitor bites, including swelling and pain, are caused by mild envenomation.1
