A common bony bream (Nematalosa erebi) has been caught in South Australia's Lake Bonney… and it has two mouths. The freshwater species is found across much of Australia, but it normally doesn't look like this.
The unusual fish was alive when it was captured in a net and pulled from the lake, which is located in the east of the state of South Australia.
Fascinatingly, both mouths seem to be joined together.
"The top one opens and closes but the bottom one looks permanently open," Garry Warrick, who caught the fish, told ABC journalist Malcolm Sutton. "Other than that, it looks like a normal fish."
Warrick, who has been a commercial fisherman in the region for 30 years, said that he's seen a few deformed carp during his time, but this is the first time he's caught a bream like this.
Although both these species are extremely rare, finding an animal with two mouths is even more unlikely, as it requires a random genetic mutation to occur.
Even more unusual was this salamander, which was born in Israel last year with two heads.
It just goes to show that even when you think you've seen it all, nature can still surprise you.
