The lace monitor is a large lizard that lives in eastern Australia, and it can grow up to 2 metres long. It is a skilled climber that often lives in trees, and it is one of the country's biggest monitor lizards. It is also known as the tree goanna.1

Inici

Lace monitors live in open and closed forests. They often shelter in tree hollows, under fallen trees or large rocks. They also visit places where people live, raiding chicken coops and rummaging through rubbish bins and garbage bags in picnic and recreational areas.1

Què menja?

Lace monitors mainly eat carrion, which is meat from animals that are already dead. They also eat insects, reptiles, small mammals, birds, and eggs and young birds and mammals, especially in spring and early summer. They search for food on the ground and retreat to a nearby tree if disturbed.1

Poder del verí

Mossegades

El verí surt pels ullals o les dents quan mossega.

Què fa el seu verí?

Lace monitors have venom glands, and their venom is similar to snake venom, but it is not strong enough to cause serious harm. A bite on the hand can cause swelling within minutes, localised disruption of blood clotting (the blood clots less well in that area), and shooting pain up to the elbow. This pain can often last for several hours.1

Its venom is not enough to cause serious harm. Scientists have cautioned that calling these lizards venomous overestimates the medical risk to bite victims.1

Què fa quan té por?

When disturbed, lace monitors retreat to a nearby tree.1

Estigues segur

No toquis, atrapis ni molestis mai un animal salvatge, encara que sigui petit i encara que sembli adormit o mort.
Deixa-li espai. Si en trobes un, mantén la calma, recula a poc a poc i deixa que segueixi el seu camí.
Si te'n mossega un: mantén la calma, no et moguis, truca al número d'emergències (112, 000, 911) o ves de pressa a un hospital. Recorda com era, una foto ajuda.

No va a per tu. Fa servir el verí per caçar o per defensar-se, i prefereix mil vegades amagar-se. Més sobre com estar segur

Dades

Populations near rubbish tips were thirty five times greater than in natural forest, and individuals were around twice as heavy.1

Lace monitors quickly learned to avoid cane toads after they had been poisoned by them.1

One lace monitor was recorded climbing a brick wall to find shelter during a thunderstorm.1

Its closest living relative is the Komodo dragon.1

Desmuntamites

Mite: Bites from monitors were thought to be dangerous mainly because of infection from bacteria in their mouths.

Veritat: Researchers found in 2005 that the immediate effects of bites were more likely caused by venom.1
