BivalvulidaW
Bivalvulida

Bivalvulida is an order of myxosporean parasites which contains a number of species which cause economically significant losses to aquaculture and fisheries, such as Myxobolus cerebralis and Ceratomyxa shasta. The Myxosporean stages of members of the bivalvulida are characterised by their two spore valves, which meet in a "suture line" which encircles the spore. They usually contain two polar capsules, but species have been reported which contain either one or four.

ForskaliaW

Gastrovascular cavityW
Gastrovascular cavity

The gastrovascular cavity is the primary organ of digestion and circulation in two major animal phyla: the Cnidaria and Platyhelminthes (flatworms). The cavity may be extensively branched into a system of canals. In cnidarians, the gastrovascular system is also known as the coelenteron, and is commonly known as a "blind gut" or "blind sac", since food enters and waste exits through the same orifice.

GeryoniaW
Geryonia

Geryonia is a monotypic genus of hydrozoans in the family Geryoniidae. It is represented by the species Geryonia proboscidalis which occurs in the Mediterranean and subtropical seas. In the Mediterranean the species is more numerous and the polyps are larger than in other parts of the world. The diameter of a polyp can be up to 80 mm, while in Florida and the Bahamas it is rare to find specimens of more than 50 mm in diameter.

Metridium dianthusW
Metridium dianthus

Metridium dianthus is a species of sea anemone in the family Metridiidae. It is found in the northern Atlantic Ocean and in the northeast Pacific Ocean. There is also a record from South Africa, possible resulting from an introduction.

Myostaurida is a suborder of jellyfishes. It contains four families.

MyxobolidaeW
Myxobolidae

Myxobolidae is a family of myxosporean parasites which typically infect freshwater fishes, and includes the economically significant species, Myxobolus cerebralis. They have been shown to have a complex life cycle, involving an alternate stage in an invertebrate, typically an annelid or polychaete worm.

MyxobolusW
Myxobolus

Myxobolus is a genus of myxozoa that includes important parasites of fish like Myxobolus cerebralis. The genus is polyphyletic, with members scattered throughout the myxozoa. Some stages of Myxobolus species were previously thought to be different organisms entirely, but are now united in this group.

Myxobolus spinacurvaturaW

Myxobolus spinacurvatura is a species of Myxozoa in the family Myxobolidae, that inhabits the Mediterranean Sea.

PrimnoidaeW
Primnoidae

Primnoidae is a family of soft corals.

StaurozoaW
Staurozoa

Staurozoa is a class of Medusozoa, jellyfishes and hydrozoans. It has one extant order: Stauromedusae. A fossil group called Conulariida has been proposed as a second order, although this is highly speculative. The extinct order is largely unknown and described as a possibly cnidarian clade of marine life with shell-like structures, the Conulariida. Staurozoans are small animals that live in marine environments, usually attached to seaweeds, rocks, or gravel. They have a large antitropical distribution, a majority found in boreal or polar, near-shore, and shallow waters. Few staurozoans are found in warmer tropical and subtropical water environments of the Atlantic, Indian, and Pacific Ocean basins, but most are known from the Northern Hemisphere. Over the years their number of species has increased, thus right now it is said to have an estimated 50 species.
