We have applied «whole - genome shotgun sequencing» to microbial populations collected en masse on tangential flow and impact
filters from seawater samples collected from the Sargasso Sea near Bermuda.

seawater volume, which was pumped through external ports at predetermined times, and multiple 200um - mesh
filters retained the plankton
from separate samples.
Baleen whales are a group of Mysticeti, large whales usually
from colder waters that lack teeth but have baleen plates in the upper jaw which are used to
filter food such as krill out of large quantities of
seawater.
A flow meter measured

But at some point during whale history, the ancestors of modern mysticetes replaced teeth with baleen, fibrous plates that
filter out small bits of food
from seawater like a giant sieve.
And it had a large set of teeth with no evidence of the comb - like fringes used by other baleen whales to

from seawater.
A big limitation in existing nanofiltration and reverse - osmosis desalination plants, which use
filters to separate salt
from seawater, is their low permeability: Water flows very slowly through them.
(A point made with a vivid irony by Arthur C. Clarke at the end of one of his «Tales
From The White Hart» (paraphrased): «It's quite probable that even now, molecules of the late professor are passing through the very
seawater filter that he devised...»)
