Video: Octopus Glides Through Plastic Maze

January 16, 2007—It has no backbone—in fact, it has no bones at all. But this octopus ain't afraid of being caught in a tight space.

Lacking a skeleton and gas bladders, an octopus can pretty much squeeze itself into the smallest of crevices. Even a 600-pound (272-kilogram) titan can slither through tubes no wider than the diameter of a U.S. quarter—about an inch, or 24 millimeters.

Watch as a cyanea octopus winds its way through a clear plastic maze, and find out why the creature once known as the devilfish hardly ever feels the heat in cramped quarters.
