Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 0.5 cm TL male/unsexed; (Ref. 359)
A minuscule to tiny, elongate fluke with the oral and ventral suckers close together. Oral sucker: less than 1/2 the diameter of the ventral sucker. Tail: more than 1/3, but less than 1/2 the total body length. Deep striations (cuticular denticulations): occur on the sides of body. Uterus: containing eggs extends into the tail; that the intestinal ceca stop well short of the end of the tail; and that the winding vitellaria are confined in midbody and do not extent to the tail (Ref. 359).
Length: 0.09 to 0.48 cm (Ref. 359). Associations: In 52 bar jacks from Bermuda infected with this worm, 10 had double infections with Alcicornis carangis, 7 with Prosorhynchus pacificus, and 10 had triple infections with all 3 flukes. Location in Host: Stomach or gills. Flukes in the gills have been reported by several authors, and probably indicate this worm's ability to leave dead fishes. Host Specificity: reported from a wide variety of fishes, but it may prefer jacks (Ref. 359).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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
