Desert monitor

Varanus griseus

只是会疼会疼，但不会对你造成严重伤害。

咬伤吃：肉

The desert monitor is a large lizard that lives across North Africa, Central Asia and parts of South Asia. It can grow to almost 2 metres long and hunts a wide range of animals, including snakes. Its bite can inject venom, which is why it is worth knowing about.1

怎样认出它

Body colour ranges from light brown and yellow to grey.1
Many have horizontal bands on the back or tail, and yellow spots across the back.1
Young lizards are bright orange with distinct bands across the back, which may fade as they mature.1
Nostrils are slits set farther back on the snout, closer to the eyes than the nose.1
Males are larger and more robust than females.1

毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

Its bite can introduce venom through venom glands in the lower jaw. The venom has a neurotoxic effect, which attacks the nerves. In humans, symptoms can include nausea, vomiting, dizziness, muscle pain, a fast heartbeat, difficulty breathing and diarrhoea. Symptoms can start within about 20 minutes and last around 24 hours, although itching at the bite area can last for at least two months.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

它害怕时会做什么？

When its body temperature is below 21 °C and it is chased by a predator, it will not run away. Instead it holds its ground and becomes extremely aggressive.1

如果它咬人

清洗伤口，让人保持冷静并就医。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

Their running speed depends on body temperature. It rises from a little over 1 metre per second at 21 °C to around 3 metres per second at 37 °C.1

Desert monitors are good swimmers and divers, and they sometimes enter water to hunt for food.1

They can live in cold places. The species is present as far north as south-west Kazakhstan, which makes it one of the few monitor lizards that tolerate cold temperatures.1

In Morocco, many desert monitors die after climbing into concrete rainwater wells called matfias and becoming trapped.1

Some populations in the Indian subspecies do not truly hibernate. Instead they slow down, become lethargic and stop feeding from December to March.1

谣言粉碎机

谣言： Only snakes, Gila monsters and beaded lizards have venom.

真相： Venom was once thought to be unique to these animals, but this is no longer the case. Venom glands are found in the lower jaws of most, if not all, monitor lizard species.1
