Tubelip wrasses live on coral reefs stretching from the eastern coast of Africa to far-flung atolls in the South Pacific. They get their name from their bizarre lips, which are conspicuously curled, making them look like someone glued a PVC pipe onto their face. It's these lips that allow the wrasse to feed on their favourite food -- coral -- and scientists have only now detailed how in a new paper in the journal Current Biology, revealing a strange predation mechanism never before described by science. The technique basically involves vanquishing food with a slime-slicked, World's Worst First Kiss, over and over again.
