Had a look at that, poor piglet!!
I'm a big fan of the varanid's. We've got the next size down, the perentie, a magnificent lizard. But the saltwater crocodile smashes them all. Pigs are just a snack for them & the feral pigs know it. They are something to be very, very wary of.
Makes the American gator look like a toothless salamander.
On the subject of predatory animals, last weekend I went to the funeral of the daughter of a very good friend of mine. She was 16, killed by a shark while swimming in the river. Had known her since she was born & her devoted parents had put a lot into making her a confident, nature girl. Really sad.
