Which percent of animal species live in the ocean?

Question

please give me your source if you have one

Answer 1

We really don't know since there are new species discovered very recently ....estimate...more than 70% because the ocean is so deep there are more poss. that there are more....

Answer 2

No one knows, because there are so many kinds
of organisms that have never been discovered
and described. Hundreds if not thousands of new ones are described every year. Roughly
a million and a quarter species are currently
known. Estimates of how many actually exist
run from about five or six million to thirty million.
The thirty million estimate is considered to be
probably too high by some people. The idea
from another answerer that 70% of species may
live in the ocean is wildly wrong. The percentage is likely to be nearer ten to twenty.
This is because the great majority of known
living species, particularly insects and nematodes, live on land. There is a greater
diversity of phyla living in the ocean, but not of
species.

Answer 3

I don't know a percentage, but probably a minority, since insects outnumber all other known animal groups combined. On the other hand there are a huge number of undiscovered marine organisms. On the other hand there are also a huge number of undiscovered insects. So I'd still go with marine species as a minority.
