Fish That Live Upside-Down

The Whipnose Anglerfish is a deep sea creature which was recently discovered to live its life upside-down. The reason for this behaviour is that while most anglerfish dangle their lure in front of their face, the Whipnose has a lure that can grow up to four times the length of its body. Because it swims upside down, the peculiar fish has a lower risk of biting its own appendage. The Whipnose Anglerfish was discovered by japanese researchers back in 2011, but back then the fish was believed to be a single incident that wasn’t typical behaviour. 

Now, the Whipnose has been sighted again, and again it has been seen upside-down only, which means that it most likely is a behavioural trait of this specific type of anglerfish.
