In Western Australia, these dolphins have taken on an even tougher challenge.
The fish have taken refuge close to the beach where the water is only a few
centimeters deep. Tail-slapping is a method dolphins often use to stun their
prey, but it doesn't seem to work here. The fish are tantalizingly close, but
they're still out of reach. So the dolphins try another technique. Vigorously
pumping their tails, they work up some speed and then they hydroplane. Their
momentum carries them right through the shallowest waters and onto the fish. Now
they're in real danger of being stranded. But fortune favors the brave. Younger
dolphins lie alongside, watching. But, so far, only eig ht individuals here have
mastered this daring technique.
