Trematoda | Azygiida
Environment / Climate / Range
Northwest Pacific, Atlantic Ocean, Mediterranean and the Black Sea.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 0.2 cm TL male/unsexed; (Ref. 359)
Length: 0.10 - 0.21 cm . A bullet-shaped fluke with the oral and ventral suckers less than 1 ventral sucker width apart. Oral sucker: Approximately 1/3 the width of the ventral sucker. Tail: usually extended from the body, but can be contracted into the body, and is more than 1/3, but less than 1/2 the total body length (when extended). Compact and rounded lobe of vitellaria is posterior to the ovary. Testes: touching or slightly separated, side-by-side on a slight diagonal, just posterior to or slightly under the ventral sucker. Egg-filled uterus does not extend to the end of the intestinal ceca or into the tail. Intestinal ceca either do not extend into the tail or just barely do so (Ref. 359).
Length: 0.10 to 0.21 cm (Ref. 359). Host Specificity: This fluke apparently has little host preference since it occurs in a great variety of fishes. Its rarity in great barracuda suggests that this is a false host (Ref. 359). Members of the class Trematoda are parasitic, thus requires a host to survive. Life cycle: Eggs are passed on to the feces of the hosts. Embryos hatch into miracidia and penetrate the tissues of snails where they further undergo three stages: sporocysts (Ref. 833).
