Robots have discovered 39 potentially new species at the bottom of the ocean.

Researchers at the Natural History Museum in London said the undescribed organisms represent a fraction of the undiscovered species from the deep sea, which scientists are working to understand.

A remotely operated vehicle allowed the samples ― collected from the abyssal plains of the Clarion-Clipperton Zone in the central Pacific to be brought to the surface.

This enabled scientists to get a much better idea of the organisms living at depths of 3,100 to 5,100 meters below sea level.

In the past animals from this area had been studied only in photographs.
