meiobenthos
Quick Summary
Meiobenthos are organisms found in the seafloor sediments that range in size from 0.1 to 1 millimeter. These organisms include various types of worms, such as polychaetes and nematodes, as well as small crustaceans like copepods and ostracodes, and other small invertebrates like turbellarians and foraminiferans.1
The variety and abundance of meiobenthos are influenced by factors such as latitude, depth, water temperature, salinity, and the nature of the seafloor substrate. Their primary food sources are plankton and organic debris from land.1

Meiobenthos, those organisms between 0.1 and 1 mm in size, include polychaetes, pelecypods, copepods, ostracodes, cumaceans, nematodes, turbellarians, and foraminiferans. The microbenthos, smaller than 0.1 mm, include bacteria, diatoms, ciliates, amoeba, and flagellates.

These larger microbes, which include foraminiferans, turbellarians, and polychaetes, frequently dominate benthic food chains, filling the roles of nutrient recycler, decomposer, primary producer, and predator. The microbenthos are those organisms smaller than 1 millimetre; they include diatoms, bacteria, and ciliates.
