I've picked the one's I think are weird
Aye-aye
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.
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), resembling the ears of Walt Disney's flying elephant. They are benthic creatures, living at extreme depths, and are some of the rarest of the Octopoda species
Which one's do you find the weirdest?
