Alien life? No.

The Pyrostremma spinosum, or pyrosome, is a sea creature so rare it was dubbed the "unicorn of the sea". It can grow up to 90 feet long -- the equivalent of two buses laid end-to-end.

Its hollow, translucent, cylindrical body is made up of thousands of tiny clones called zooids that pull water through its tubes and feed on plankton before pushing the filtered water back out.
