”The dumbo octopus is small, compared to other octopodes. Its average size is between 20-30 cm (slightly larger than an adult guinea pig), but scientists found one specimen as large as 1.8 meters—that’s almost six whole feet of adorableness! They have a variety of shapes and colors and have the ability to “flush” or camouflage themselves to their environment.”
