Nanobes are the minutest creatures on our planet. They barely touch the minimum requirements to be considered as a living creature. They are so minute that they can only be seen under special microscopes. They are 1000 times smaller than body cells, i.e. a length of 20 to 150 nanometers! They were discovered under the ocean by Dr. Phillipa Uwins from an Australian university named Queensland University. She encountered them during oil drilling. This creature has shocked the researchers for its level of minuteness and therefore it tops the list of the top 10 smallest things in the world. Nanobes are considered smallest living thing in the world.
