Dumbo Octopus
The octopuses of the genus Grimpoteuthis are sometimes nicknamed "Dumbo octopuses" from the ear-like fins protruding from the top of their "heads" (actually bodies)They are benthic creatures, living at extreme depths, and are some of the rarest of the Octopoda species.
The Aye-aye (Daubentonia madagascariensis) is a strepsirrhine native to Madagascar that combines rodent-like teeth with a long, thin middle finger to fill the same ecological niche as a woodpecker. It is the world's largest nocturnal primate, and is characterized by its unique method of finding food; it taps on trees to find grubs, then gnaws holes in the wood and inserts its elongated middle finger to pull the grubs out.

Leafy Seadragon
Named after the dragons of Chinese mythology, Leafy seadragons (Phycodurus eques) resemble a piece of drifting seaweed as they float in the seaweed-filled water. The Leafy seadragon, with green, orange and gold hues along its body, is covered with leaf-like appendages, making it remarkably camouflaged. Only the fluttering of tiny fins or the moving of an independently swiveling eye, reveals its presence.
