myxozoa
Myxozoa (etymology: Greek: μύξα ''myxa'' "slime" or "mucus" + thematic vowel o + ζῷον ''zoon'' "animal") is a subphylum of aquatic cnidarian animals – all obligate parasites. It contains the smallest animals ever known to have lived. ...

The Atlantic cod (: cod; ''Gadus morhua'') is a fish of the family Gadidae, widely consumed by humans. It is also commercially known as ''cod'' or ''codling''.[Arctogadus glacialis
''Arctogadus glacialis'', known also with ambiguous common names Arctic cod and polar cod, is an Arctic species of fish in the cod family Gadidae, related to the true cod (genus ''Gadus''). ''Arctogadus glacialis'' is found in icy water. They gr ...]

The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, urinary bladder, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume ...
s. These 3 species' spores exhibit two morphological forms: wide and subspherical, being both types
bilaterally symmetrical along the
suture line. The wide spores have a mean width ranging from 7.5-10

, respectively, while the subspherical ones range from 5.3-8μm in mean width. The subspherical forms of ''Gadimyxa'' are similar to ''
Ortholinea'', differing in the development of the spores and in the arrangement of the
polar capsule
Polar capsules are structures found in the valves of myxosporean parasites, which contain the polar filament. The polar capsule is constructed of a proteinaceous and a polysaccharide layer, both layers of which continue into the polar filament.
