New Video Shows Thresher Shark Repeatedly Using Tail to Whip Sardines

Thresher strikes at shoal of sardines with tail
Here's a stunningly beautiful video from Pescador Island in the Philippines.  The new video shows a thresher shark using its tail to whip at large shoals of sardines.

Thresher sharks have extraordinary long tails that make up nearly half their body length. And although researches had theorized that they used their powerful tails as weapons, it wasn't confirmed until the activity was captured on video.

Earlier this year, researchers from the Thresher Shark Research and Conservation Project were able to record a thresher shark using its tail as a weapon while diving at the same Philippine island.  Apparently, it was the first time the activity had been caught on video and news of the 37 second video quickly made science headlines around the world.  That video is posted below the new video.

Pescador Island shoal of sardines
This new video was posted yesterday and features some stunning close up images of shoals of sardines. Even without the later shark action, it is a beautiful and interesting video.  But alas, we are about sharks here so let's cut to the chase.

The thresher makes its first appearance at the 1:15 mark. Although it initially is shown swimming around the bait ball, it later goes on the offensive at the following time marks: 2:14, 2:47 and 3:53.  At the last mark (2:53), we get a very clear shot as the shark whips its tail directly over its head striking at the school of sardines.

This is a wild video. Enjoy.  The video was posted on Vimeo by Philippine Dive Holidays.
