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

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

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

Ana hatari gani kwa watu?

Hufanya nini akiogopa?

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

Akiuma

Osha jeraha, mweke mtu mtulivu na utafute msaada wa kitabibu.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

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

Kuvunja dhana potofu

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

Ukweli: 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
