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

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

何を食べるの？

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

毒パワー

かむ

かむときに、毒が牙や歯から出るよ。

その毒（かむ・刺す毒）はどうなるの？

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

こわいとき、どうするの？

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

かまれたら

傷口を洗い、その人を落ちつかせて、医療の助けを受けよう。

まず必ず救急番号（112、000、911）に電話しよう。これは一般的な応急手当の案内で、医療のアドバイスではないよ。応急手当の基本

安全に過ごそう

野生の動物には、小さくても、ねているように見えても、死んでいるように見えても、ぜったいにさわったり、つかまえたり、からかったりしないこと。
近づかないで。出会ったら落ちついて、ゆっくりあとずさりして、そのまま行かせてあげよう。

データ

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

うそ・ほんとう

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

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