How many species of sea life?

There are exactly 230,000 sea species in the world. Did you know that humans have only discovered about 2% of all ocean life there is? Imagine how many species there would be if we found all the species there are!

Actually, people haven't been recording how many animals are in the ocean so far. That was just an estimate, but it was said that there is a 95% chance that this estimate is right.
