If only 2% has been discovered, realize that the other 98% of the ocean holds atleast one million cryptids - thank you.

Would be many more undiscovered species than that.Imagine all the undiscovered sharks

Not sure about the figures here maybe CR knows... When they took the cameras down to film the Titanic for the Imax, they had to have massive amounts of lights to capture the documentary... during filming they found and identified dozens of new fish that were not not been seen before.

Actually CR, I saw a Imax film the other day at a huge mall. Not sure if you head it but its called the "Aliens of the Deep" which is all ALL about marine biology and the strangest fish and sea creatures in the deep waters.
