Scientists estimate at least one third of marine species remain unknown to humans

It's been said that we know more about space than we do about our own ocean, and now a group of scientists have quantified what sea creatures we may still not know of. After compiling an open access, online database of known marine species with the help of more than 270 experts, researchers estimate that the briny depths may be home to a total of one million species, with one third of them potentially remaining entirely unknown. Of the grand total, humans have described roughly 226,000 - more than 20,00 of which in the past decade - with another 65,000 tucked away in collections awaiting a write-up.
