Philippe bouchet and colleagues conducted a massive survey of marine mollusks on the west coast of new caledonia. twenty percent of the species found had only a single specimen collected. what does that suggest about the diversity of mollusks in this area?

The suggestion about the diversity of molluscs in the area is how many species from the twenty percent are probably rare. Biologists use different approaches to describe the levels of biological diversity in the marine environment.
One approach is quantitative ecologists and the other one is biogeographers who pool data on species.
Molluscs are phyla which are routinely considered in marine biodiversity surveys
