18. Musky Rat-kangaroo
Having a length of 32 cm and a 12 cm long, hairless tail, this member of the marsupial family might be the scariest one to those who are afraid of rats. The 5 toes on each of the creature’s feet suggests that it might be closely related to the primitive marsupials. However, the guy is totally harmless. It only feeds on fruits, seeds and very small invertebrates.
