  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?

Sea Lions Are Inspiring the Future of Underwater Transport

YouTube description:

Don’t be fooled by a sea lion’s big, sweet eyes and playful demeanor—these guys move through water like a torpedo. While most animals swim using a tail or fluke, sea lions clap their fore flippers into their bodies to propel themselves to incredible speeds. It’s an elegant, efficient movement that land-dweller Megan Leftwich, an associate professor of mechanical engineering at George Washington University, wants to reproduce in robotic form.
