Okay I'm downplaying his excitement; the guy's losing his stuff over this upside-down whale.

Seriously, is everyone in Australia a regular Steve Irwin when they see an animal in nature?

But to be fair, what he's witnessing is pretty amazing!

I love the drone footage of that baby and his mum. It's so cute.

If you listen closely when the over-excited Aussie isn't going on and on, you can hear the pair gently singing to each other.

Apparently, a mama whale doing a handstand like this is called tail sailing.

Whales stick their tail up and float vertically, upside down in the water. Some think it's a way for mother whales to catch a little rest while still keeping an eye on their babies.

This video explains in more detail.

There are a few other videos that show the phenomenon, like this one with a whale guide chattering excitedly.

I'll tell you this though, after watching that last one, the last place I would want to be is in a kayak edging in as close as I can when mama wakes up.

Crikey!!!
