could circle to pick them up at its leisure. "The evidence is now clear; thresher sharks really do hunt with their tails. Tail slapping is an efficient strategy for hunting schooling prey since thresher sharks are able to consume more than one prey item at a time."
Thresher sharks display predatory tail strike
Researchers led by Dr Simon Oliver, at the University of Liverpool in the UK, used underwater video cameras to record 25 instances of thresher shark hunting behaviour between June and October 2010. In many of these cases the sharks would speed in and then brake suddenly, flicking their powerful tails over their heads to slam them into the shoals (see video, above).
"This extraordinary story highlights the diversity of shark hunting strategies in an ocean where top predators are forced to adapt to the complex evasion behaviours of their ever declining prey," says Simon.
THRESHER SHARKS HAVE incredibly long, scythe like tails Adidas Energy Boost 2.0 Atr Test that make up more than half their up to 6m body length. Experts had long suspected that they used these tails as part of a hunting strategy to strike at prey, but it had never been confirmed.

of low pressure caused water in the immediate vicinity to spontaneously boil. Some sardines were hit directly in the attacks, while others were killed by the pressure wave.
Incredibly, Simon's team found that these tail slaps could lash out at up to 80km/h. The speed was such that 'supercavitation' bubbles would occur behind the moving tail tip, as a wave Cheap Nmd Human Race

Now, researchers studying pelagic thresher sharks (Alopias pelagicus) at Pescador Island in the Philippines have caught them using their tails to strike at shoals of sardines and captured it on film.
Dolphins and killer whales were already known to use tail slaps to corral and stun fish, but this behaviour has never been seen in a shark before. Sperm whales and humpback whales employ tail slaps to communicate over great distances.
