g'day.
I was watching lots of YouTube videos describing lots of venomous animals in Australia. The most shocking example I am aware of thus far is the Sydney funnel web spider. Just something as trivial as picking up a piece of loose tree bark off the ground can reveal a shocking surprise of a small but dangerous spider like that.
I also know that the sea shores around Australia might contain small sea creatures that can inject venom into the human body with a very tiny harpoon, but is enough venom to potentially kill a human.
Any more info about this?
