Fine Detritus Feeders
These
are animals which live off the fine particles of detritus. They scrape the sides
of the habitat to get food. An example of a fine detritus feeder are ostracods.
They stir up the particles with their antennae before filtering them.
Larvae
of non-biting and biting midges are
also fine filter feeders. They feed in packs and can swim rapidly in the water
column.
