Environment: milieu / climate zone / depth range / distribution range
Ecology
Host. Tropical
Atlantic Ocean and Pacific Ocean.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 17.0 cm TL male/unsexed; (Ref. 359)
This small to very large fluke is unmistakable in the stomach of wahoo; a fleshy worm that varies in size and shape; with extended worms the size of a mans finger and contracted ones about the size of a walnut. Smaller worms: still massive but they are capable of contorting into many shapes. Color: brown to pinkish. 2 suckers: easily seen and are close together on the anterior end of the worm.
Length: 0.85 to 10 cm; Live worms may extend to 17 cm. Significance: The wounds they produce and sheer size must have a negative, if unstudied, impact on big game fishes. They have also been used as biological tags (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
