These dolphins have worked out that fish out of water are much easier to catch.
By beating her tail down hard, this bottlenose dolphin stirs up the seabed.
And by swimming in a circle, she creates a ring of mushrooming mud around a shoal of fish: a fishing net made of mud.
As the net pulls tighter and tighter, the fish are trapped until there's only one way out – straight into the mouths of the waiting dolphins.

It's just amazing, I didn't know that dolphins were so intelligent, it has taken them hundreds of thousands of years of evolution to perform this technique. I have not seen a technique to hunt prey like dolphins, but I have seen on many occasions how the animals camouflage themselves very well with their surroundings to hunt, it is simply beautiful.
