On Monday, scientists from the University of British Columbia [explained](http://www.eurekalert.org/pub%5Freleases/2015-05/cp-tgw042715.php) how they do this — stretchy nerves. “These large nerves actually stretch and recoil like bungee cords,” A. Wayne Vogl, an author of the study to be published in May in the journal _Current Biology_, said in a press release. Normally, a firm collagen wall surrounds nerves and if stretched they become damaged. For example, humans can suffer from “nerve stretch injury.” In rorqual whales, the nerves are packed into a centralized core surrounded by limber “elastin fibers.” When the whale opens its mouth the design enables the nerve fibers to unfold. The feeding whale will then gulp-up floating prey before the nerve snaps back and the sea water is filtered through baleen plates in its mouth, leaving behind a massive quantity of small prey. What’s more, the discovery was an accident. A team member picked up what he believed to have been a blood vessel and stretched it. But upon closer examination the researchers realized that the blood vessel was in actuality a nerve. The scientists plan to keep studying the whales in the hopes to better understand the folding and unfolding process. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3846646/whales-biology-blue-whales-nerves-nervous-system/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3846646/whales-biology-blue-whales-nerves-nervous-system/"},"headline":"Gigantic Whales Eat Huge Amounts Thanks to 'Bungee-Cord' Nerves","datePublished":"2015-05-05T08:39:06.000Z","dateModified":"2026-02-22T06:55:35.261Z","description":"The discovery was an accident","url":"https://time.com/3846646/whales-biology-blue-whales-nerves-nervous-system/","keywords":["animals","Biology","Research","Whales","Ocean","Discovery","fish"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt8a646eeeed484e97/6987ee5835ba6f3f3dc0b347/rorqual-whales-nerves.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Kevin McSpadden","jobTitle":null,"url":"https://time.com/author/kevin-mcspadden/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt8a646eeeed484e97/6987ee5835ba6f3f3dc0b347/rorqual-whales-nerves.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Humpback whale breaches 3 miles off of Rockaway Beach on August 31, 2014 in New York City","caption":"Humpback whale breaches 3 miles off of Rockaway Beach on August 31, 2014 in New York City","creditText":"Artie Raslich—Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/animals/","name":"animals"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3846646/whales-biology-blue-whales-nerves-nervous-system/","name":"Gigantic Whales Eat Huge Amounts Thanks to 'Bungee-Cord' Nerves"}}]}] ```
