Decided to take a trip North of Cairns to Cape Tribulation and the Daintree River.
View from atop Cape Tribulation
Did not see as many as I would like due to the high water levels. But these waters are loaded with them. The darker and dirtier the more dangerous the water is.
You canon tell by the pictures but these fellows are about the size of your hand.
There were about five hanging around the washrooms. Makes you take a piss real fast thinking they may drop down on you.
