  - 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?
  Post and share it here - VideoSift is the best video aggregator on the Web, where we share, discuss, promote, and interact with the best videos out there on the web. Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

The Nautilus - David Attenborough

submitted by mauz15

1 decade 5 years 7 months 1 week ago

"Having survived relatively unchanged for millions of years, nautiluses represent the only remaining members of the subclass Nautiloidea, and are often considered to be "living fossils".

The Nautilus maintains buoyance through a gas passed through a tube in the shell tube called a siphuncle. This also helps the animal stay upright in the water. The Chambered nautilus has about 90 small suckerless tentacles found on the body close to where it is attached to the shell. This mollusc has eyes but they do not have a cornea or lens.
