No, no. I beg to differ.

The greatest single animal species biomass is the geoduck, which cover the soft bottom of puget sound at a density of up to a clam per square foot.

Within the waters of the Puget Sound there are an estimated 500 million pounds of geoducks or on the order of 300 million clams- the largest biomass of any marine animal in the region.

However, the ratfish is supposedly the most abundant fish.
