Any worm that lives in a marine environment is considered a water worm. Marine worms are found in several different phyla, including the Platyhelminthes, Nematoda, Annelida, Chaetognatha, Hemichordata, and Phoronida. For a list of marine animals that have been called "sea worms", see sea worm.
Sea bass is a common name for a variety of species of marine fish. Many fish species of various families have been called sea bass.
Acoelomorpha is a subphylum of very simple and small soft-bodied animals with planula-like features which live in marine or brackish waters. They usually live between grains of sediment, swimming as plankton, or crawling on other organisms, such as algae and corals. With the exception of two acoel freshwater species, all known acoelomorphs are marine.
Fragmentation in multicellular or colonial organisms is a form of asexual reproduction or cloning, where an organism is split into fragments upon maturation and the split part becomes the new individual.
Symsagittifera roscoffensis, also called the Roscoff worm, the mint-sauce worm, or the shilly-shally worm, is a marine acoel worm. The origin and nature of the green color of this worm stimulated the intrigued zoologists in the 1870's. It was discovered that the coloring resulted from the symbiosis between the animal and a green micro-algae, the species Tetraselmis convolutae, hosted under its epidermis. It is the photosynthetic activity of the micro-algae in hospite that provides the essential nutrients for the worm. This partnership is called photosymbiosis, from "photo", "light", and symbiosis "who lives with". These photosynthetic marine animals live in colonies on the tidal zone.
Convolutidae is a family of acoels, belonging to the phylum Xenacoelomorpha. This family contains more than a third of all known acoel species.
Copium is a genus of lace bugs in the family Tingidae.
Actinoposthiidae is a family of acoels.
Marginellinae is a taxonomic subfamily within the larger family of Marginellidae, a group of small sea snails, marine gastropod molluscs in the superfamily Volutoidea.
Paratomy is a form of asexual reproduction in animals where the organism splits in a plane perpendicular to the antero-posterior axis and the split is preceded by the "pregeneration" of the anterior structures in the posterior portion. The developing organisms have their body axis aligned, i.e., they develop in a head to tail fashion.
Convolutriloba is a genus of marine acoels.
Convoluta convoluta is a small acoel in the family Convolutidae. Native to the Baltic Sea, it invaded the Gulf of Maine in the late 1990s.
William Macnae, 1914-1975, was a South African zoologist and malacologist. He was a Scottish born-and-educated marine ecologist and moved to South Africa in 1948.
Astomonema is a genus of nematode worms in the family Siphonolaimidae. They lack a mouth or conventional digestive tract, but contain symbiotic sulfur-oxidizing bacteria that serve as their primary food source. They live in the marine interstitial habitat.
Dendrocoris is a genus of stink bugs in the family Pentatomidae. There are about 11 described species in Dendrocoris.
Thyanta is a genus of stink bugs in the family Pentatomidae. There are about 19 described species in Thyanta.
Garganus is a genus of plant bugs in the family Miridae. There are about 12 described species in Garganus.
Hesperocorixa is a genus of water boatmen in the family Corixidae. There are more than 20 described species in Hesperocorixa.
Actinoposthia is a genus of acoels belonging to the family Actinoposthiidae.
Asiarcha is a genus of bugs in the family Tessaratomidae. Species are known from South and Southeast Asia.
