Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Moderate-sized; elongate fluke has the ventral sucker located on a projection from the body. Oral sucker: smaller than the ventral sucker and moderately separated from it (more than 2, less than 3 ventral sucker diameters). There is a hood-like lobe that hangs over the oral sucker and the ventral sucker is enclosed by a fold of the body wall. No tail is present.
Length: 0.13 to 0.24 cm. Associations: The numbers of this fluke were positively correlated with the numbers of Caligus productus and Euryphorus nordmanni on the gills of dolphin, which suggests that they may, in some way, aid each other in parasitizing this host. Host Specificity: only occurs on dolphin, but not often enough to be a characteristic parasite. Damage to Host: Moderate infections may injure dolphin (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
