I'm not one for posting pictures of cute stuff on the internet, but animals from the bottom of the ocean are always interesting, so it's a good excuse. Apparently there are 19 described species in the Opisthoteuthis genus, but this isn't one of them and it is awaiting a name. Specimens have been in collections since 1990, but managing to keep one in an aquarium is new. The Monterey Aquarium did such a good job that it even laid eggs. Anyway, if you haven't seen the video before, have a look and you'll see why they want to call it Opisthoteuthis adorabilis.
