Myxozoa (etymology: Greek: μύξα myxa "slime" or "mucus" [2] + thematic vowel o + ζῷον zoon "animal" [3]) is a subphylum of aquatic cnidarian animals – all obligate parasites. It contains the smallest animals ever known to have lived.
The snubnosed eel, Simenchelys parasitica, also known as the pug-nosed eel, slime eel, or snub-nose parasitic eel, is a species of deep-sea eel and the only member of its genus. Some authors classify it as the sole member of the subfamily Simenchelyinae of the family Synaphobranchidae , or cutthroat eels , while others place it in its own ...
Swedish mycologist Elias Magnus Fries described numerous slime moulds as Myxogasteres in 1829. [5] Species in the class Myxogastria are colloquially known as plasmodial or acellular slime moulds. Some consider the Myxogastria a separate kingdom , with an unsettled phylogeny because of conflicting molecular and developmental data.
Slime molds contribute to the decomposition of dead vegetation; some are parasitic. Most slime molds are terrestrial and free-living, typically in damp shady habitats such as in or on the surface of rotting wood. Some myxogastrians and protostelians are aquatic or semi-aquatic. The phytomyxea are parasitic, living inside their plant hosts.
A closeup of the skin on an Eldon's galaxias. The slime coat (also fish slime, mucus layer or slime layer) is the coating of mucus covering the body of all fish.An important part of fish anatomy, it serves many functions, depending on species, ranging from locomotion, care and feeding of offspring, to resistance against diseases and parasites.
The parasite eggs are passed with the feces of the host, which then are eaten by a terrestrial snail (first intermediate host). The fluke matures into a juvenile stage in the snail, which in an attempt to protect itself excretes the parasites in "slime-balls". The "slime-balls" are then consumed by ants (second intermediate hosts).
The term plasmodium, introduced by Leon Cienkowski, [2] usually refers to the feeding stage of slime molds; these are macroscopic mycetozoans. [3]The multinucleate developmental stages of some intracellular parasites, namely Microsporidia (now in Fungi) and Myxosporidia (now in Cnidaria), former cnidosporans, are also sometimes called plasmodia.
The next morning, white translucent slime was reportedly discovered on the lawns and sidewalks of the town. [24] In 1997, a similar substance fell in the Everett, Washington, area. [citation needed] Star jelly was found on various Scottish hills in the autumn of 2009. [5] Blue balls of jelly rained down on a man's garden in Dorset in January 2012.
