Whales' Mouths Have Nerves With An Amazing Property

Newly discovered nerves in the mouths of massive whales can unfold, nearly doubling in length, and recoil like a bungee cord. These stretchy nerves could explain how the whales are able to eat by ballooning their mouths during dives.
Researchers discovered the surprisingly elastic nerves after collecting samples from a commercial whaling station in Iceland.
Wayne Vogl, a professor of cell and developmental biology at the University of British Columbia in Canada, said "This discovery was totally unexpected and unlike other nerve structures we've seen in vertebrates, which are of a more fixed length."
