Are any of these Dangerous to humans-Fauna and flora?

Question

African mesquite, African scrub flower, African Peyote Cactus, African Welwitchsia, African Sombrero Cactus.

Locust, African Monitor, African Oryx, African Scorpion.

Answer 1

yes I would suppose that some of them are.

Answer 2

I don't know some of the common names you use but peyote is fine if you don't ingest it. Cactus is no problem unless you touch it (and isn't native to Africa anyway). Monitors are big, foul-tempered, and have nasty claws. Scorpions can sting. Vultures are not much of a problem unless you are dead or dying. Locusts are dangerous to crops but are supposedly edible. Never tried one myself.
