Anywhere from one-third to two-thirds of sea life has not been discovered yet, by their estimate. Most of those hidden sea creatures are probably crustaceans, mollusks, worms and sea sponges, they said.
How did Earth get so many species?
Just why some groups contain large numbers of species while others don't has long puzzled biologists. One of the main explanations has been geological age - older groups of organisms are more diverse because they have simply had more time to accumulate greater numbers of species.
How did ocean water get salty?
Salt in the sea, or ocean salinity, is mainly caused by rain washing mineral ions from the land into water. ... When rain falls, it weathers rocks, releasing mineral salts that separate into ions. These ions are carried with runoff water and ultimately reach the ocean.

Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
How many animals are undiscovered?
Scientists figure there are still over five million species waiting to be found. The table below lists how many undiscovered species exist for each type of plant and animal. So far, zoologists have reported on nearly all the mammal and bird species currently living on earth.
