Scientists say Earth has 8.8 million species and we have only discoverd 1.9 million of them so far.

Well known Harvard biologist, Edward O'Wilson said there would be potential benefits from this undiscovered species. Some of modern medicine come from unusual plants and animals.

Researchers from University of Hawaii, Worm and Camilio Mora came up with complex mathematical method to estimate the number of unknown species.

Some of the interesting recent discoveries are : a psychedelic frogfish, a lizard the size of a dime and even a blind hairy mini-lobster at the bottom of the ocean.

Even for an imagination, it is exciting to think that some of unknown species may reside in our backyard.
