Macrofauna

Small marine animals called macrofauna -- snails, worms, clams, and other creatures no bigger than a pencil eraser -- live and feed in the seafloor sediment. ❋ PhysOrg Team (2010)

But polar cod, capelin, sand eel (Ammodytes spp.), and squid (Illex illecebrosus) are probably the most important pelagic/semi-pelagic macrofauna acting as forage for fish such as Greenland halibut and cod, marine mammals, and seabirds. ❋ Unknown (2009)

Benthic invertebrate macrofauna of the eastern Bering/Chukchi continental shelf. ❋ Unknown (2009)

The continual supply of oxygen could support roughly 3 billion kilograms of macrofauna, assuming similar oxygen demands to terrestrial fish. ❋ Unknown (2009)

Greenberg says that the concentrations of oxygen would be great enough to support not only microorganisms, but also “macrofauna”, that is, more complex animal-like organisms which have greater oxygen demands. ❋ Unknown (2009)

These are low in diversity but high in populations for some of the macrofauna, some of which are relicts of earlier periods, others at the extremes of their latitudinal and environmental distribution. ❋ Unknown (2008)

The low number of benthic macrofauna species in the arctic intertidal zone is usually attributed to ice scouring ❋ Unknown (2010)

In the deep Arctic Ocean, the number of benthic macrofauna species varies from 0 to 11 ❋ Unknown (2010)

And among hundreds of species of macrofauna (animals about the size of an earthworm) collected in different areas, 50 to 85 percent were unrecognized.

Paulay estimates more than 5 percent of the macrofauna his team collects are new genera and species. ❋ Unknown (2009)

Among the hundreds of species of earthworm-sized macrofauna found at different sites, 50pc to 85pc were unrecognised. ❋ Unknown (2009)

The more stressed phases are dominated by a species-poor community composed of a few amphipods, polychaetes, and sipunculids, although macrofauna often exhibits aggregations at the edges of hypoxic zones. ❋ Unknown (2009)

Re: symbiosis with sulfur-fixing bacteria I’m assuming that’s what bacteria associated with pyrite would be doing: don’t forget all of the macrofauna in seafloor hydrothermal vent systems. ❋ Unknown (2006)
