00:09found humpback whales are also clever hunters this video was captured in the waters just off
00:14the coast of southeast Alaska what you're seeing are concentric bubbles that have been blown by the
00:19whales but they're not just for show new research by investigators with the University of Hawaii at
00:24Manoa have found these bubble rings are actually nets which help the whales catch krill with the
00:29researchers writing that these whales skillfully blow bubbles in patterns that form nets with
00:34internal rings actively controlling details like the number of rings the size and depth of the net
00:39and the spacing between bubbles finding that they help them guide and trap krill and consume seven
00:44times as much food what's more the experts say this appears to be a learned behavior as not all humpbacks
00:50hunt this way experts say the whales time in these Alaskan waters is critical as they migrate to
00:55warmer waters for calving season during that time the adults do not eat meaning they need to get
00:59their fill to last them throughout that season
