Which of these sharks is not generally dangerous to humans?

THEIR name. ITS origin.

In Australia we have all four.

They all still bite ..don't they ?

Nurse sharks bite people regularly. the won't bite unless provoked, but they will bite.

A few years back, I saw a guy on "Shark Week" swimming with Nurse sharks. Every time a shark swam past, this dork would grab it and kiss it on the snout. Well, Nurse sharks might not bite very often, but they did that day. When he picked up the last one, it bit his upper lip off.

They are wild too … so all sharks can be dangerous. I’ll stay away from them all thanks

I have swam with then!!!

I wish I could get some to clean around here

Dalia, neither have I

Generally known in Australia as Grey Nurse shark

Nurse shark? I haven't heard it before
