Trematoda | Strigeata
Environment: milieu / climate zone / depth range / distribution range
Western Central Atlantic.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 0.3 cm TL male/unsexed; (Ref. 359)
Length: 0.09-0.25 cm. Minuscule; elongate worm with a distinctive wedge-shaped, relatively large, elongate rhynchus with 7 tentacles. Each tentacle: 2 side branches of different sizes. Mouth: opens approximately in mid-body (Ref. 359).
Length: 0.09 to 0.25 cm. Significance to Sport Fishing: If it is restricted to the West Indies, this fluke might have some potential as a temporary biological tag (Ref. 359). Stomach or intestine (bar jack). We found 100 flukes in the pyloric ceca of a horse-eye jack.
Host Specificity: parasite may be genus specific (Caranx), or family specific to jacks. The high numbers in horse-eye jack and lower ones in bar jack, could suggest that horse-eye jack might be the preferred host. This parasite appears to be a secondary parasite of both hosts. Horse-eye jack was a new host (Bunkley-Williams, Dyer and Williams 1996).
Damage to Host - The very heavy infection of more than 100 worms in the pyloric ceca could easily stunt or injure the host. Habitat (vertebrates): bar jack; blue runner; horse-eye jack; yellow jack (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).
