How Many Species Live in the Ocean? The number of species that live in the ocean is unknown . While scientists estimate that 91 percent of ocean species have yet to be classified, the global scientific community continues to amass as much knowledge as possible about ocean life.
Considering current rates of description of eukaryote species in the last 20 years (i.e., 6,200 species per year; ±811 SD; Figure 3F–3J), the average number of new species described per taxonomist's career (i.e., 24.8 species, ) and the estimated average cost to describe animal species (i.e., US$48,500 per species ) and assuming that these values remain constant and are general among ...
The nearshore zone of the ocean—defined by the Census as the coastal areas to a depth of around 65 feet (20 meters)—is the most-studied region of the ocean because it is so easy to access from land. But surprisingly, we still don’t know how many species live by the shore: estimates vary widely, from 178,000 species to more than 10 million.

The Census of Marine Life was an international project spanning 10 years that recorded the diversity, distribution, and abundance of life in the ocean. More than 2,700 scientists from 80 nations contributed to the Census. The results of their research, which included 540 marine expeditions, were reported at The Royal Society, London, in October 201...
The publicly accessible online World Register of Marine Species (WoRMS) founded in 2007 has greatly facilitated access to knowledge on the already known species by a much broader public of professional and non-professional scientists from throughout the world. There have never been so many authors involved in new species descriptions. A significant...
