“It’s equivalent to if you could shove your hand into your mouth and under the skin right down to your belly button,” Robert Shadwick, a zoologist from the University of British Colombia, told the BBC when describing how the creature feeds. “A sort of pouch under the skin, which balloons out enormously — almost into a spherical bubble.”
Now that’s opening wide.
