Weird world news: It's a croc-eat-croc world Down Under

But this reptile wasn’t giving up as it swallowed a croc half its size.

The rare moment was captured by a far north Queensland tour guide near the Daintree River, Cairns.

“He was having a bit of trouble getting it down his throat,” David White of river boat tour company Solar Whisper said.

“I’m not sure if he ate it or not, but I think he did because the next week he did a lot of sunbaking with a big belly.”

He says crocodiles will often eat their own kind, including their offspring, but it’s rare to see it happen.
