Here ’s a sample of the bio - duck noise .
In a newspaper to be released tomorrowin Biology Letters , nautical life scientist Denise Risch and her team identify the sound as belonging to the minke hulk , which they overheard let out the noise while it was diving for food .
Minke whales are also among the species that are hunt mostby Nipponese whale ship .
According toSusan Milius , writing in Science News :
Very little is do it about these whales ’ vocalization ; research worker have identified only a few of the various minke species ’ sound , include a “ boing ” and what ’s call a “ Star Wars ” vocalisation . In 2013 , researchers for the first prison term placed acoustic tags on the Antarctic minke ( Balaenoptera bonaerensis ) . Tags from two whale recorded some sound already link to the specie .
But over the trend of 18 hours , one of the tag picked up bio - duck’s egg beats before and during a heavyweight ’s feeding prima donna . Because researcher observe the whales see no other nautical mammals nearby , Risch and fellow reason out April 23 in Biology Letters thatminke whales are the bio - duck .
you’re able to also hear the scientists who made this discovery talking about it ( and playing more of the sound ) ona NOAA podcast .
