The Dumbo octopus also has an adorable genus name, Grimpoteuthis†. They're bottom-feeders, spending most of their time a few cm off the sea floor (about 3000-4000m deep) looking for snails, worms, etc. 

† I genuinely don't know what the "grimpo" part refers to - it may be someone's name, or it may be related to γριπάομαι, "to be contracted", referring to how the octopus's tentacles appear to be shortened (they're actually just joined together with skin, like webbed fingers).
