Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 0.5 cm TL male/unsexed; (Ref. 359)
Length: 0.09 - 0.54 cm; cysts in the heart of a gray angelfish were 0.0218 cm; and the encysted worms were 0.0188 cm. Minuscule to tiny fluke has relatively large; distinctive; tentacle-like papillae surrounding the oral sucker. Muscular folds: visible in the sides of the neck. Ventral sucker: large and occupies more than 1/2 of the body width (Ref. 359).
Host Specificity: No host preference and occurs in a wide variety of big game fishes and other fishes. Damage to Host: cysts in the heart caused little tissue damage and no noticeable host response. Habitat (vertebrates): bar jack; little tunny; Blue runner; crevalle jack; horse-eye jack little tunny; crevalle jack; blue runner; frigate tuna; skipjack tuna; yellow jack; bullet tuna; chub mackerel; skipjack tuna; rainbow runner; chub mackerel (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
