Fungi are hypothesized to contribute to phytoplankton population cycles and the biological carbon pump and are active in the chemistry of marine sediments.

Is a jellyfish an arthropod?

Jellyfish, hydras, sea anemones, and corals make up the four classes of cnidarians.

Who discovered phylum Loricifera?

The phylum was discovered in 1983 by R.M. Kristensen, near Roscoff, France. They are among the most recently discovered groups of Metazoans. They attach themselves quite firmly to the substrate, and hence remained undiscovered for so long. The first specimen was collected in the 1970s, and later described in 1983.

What is different about Loricifera compared with other animals?

They are the first multicellular organisms known to spend their entire lives in an oxygen-free environment. It is thought they are able to do this because they rely on organelles which, unlike normal mitochondria, do not use oxygen for their energy cycle.

Is invertebrate a phylum?

Invertebrates are so diverse that they include dozens of phyla (plural). In contrast, vertebrates, animals with backbones, are only a small subgroup within one phylum. Most commonly seen invertebrates belong to one of these six phyla. If an animal belongs to one phylum, it does not belong to any other phyla.
