Filter-feeding fish accomplish a feat
that human technologies cannot: species including goldfish, menhaden and
basking sharks filter tiny algal cells or shrimp-like prey from huge volumes of
water without clogging their oral filters.

have evolved filter designs that use unknown processes to remain unclogged. So
we decided to investigate.
