Short description Morphology
The species is relatively large, has an oblong external reproductive sac; mean length measures 2.3 mm; sac ranges from pink to colorless, ovary attached to sac wall opposite pedicel; remainder of mantle cavity comprises of the brood cavity, connected to the exterior by the mesenteric canal running opposite the pedicel between the sac wall and ovary; mesenteric canal opens to the exterior obliquely opposite to the pedicel; external sac attached to host body, usually to the visceral mass of the host by the short pedicel; pedicel base surrounded by circular, amber-colored, cuticular shield bearing cocentric annulations; alimentary root system ranges from orange to bright red, circular plaque, 3-5 mm in diameter, extending within the host from pedicel outward in dendritic fashion; invasion root tissue consisting of highly vacuolated cells with darkly staining nuclei; unhatched cyprid larvae frequently found in abundance in brood cavity; cyorids possess pair of antennules, but no other appendages; mean cyprid length measures 88.9 micrometer.
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the order Akentrogonida are gonochoric. Life cycle: Nauplius larvae molt into cyprids. The female settles on a host and metamorphose into vermigon larva and then into an interna which lies into the host's cuticle. It then develops into an externa lying outside the host's abdomen. The male cypris larvae attaches to the female externa, the male then molts into a dwarf male (trichogon larva) and remains as a testis parasitic on the female. Fertilization occurs and the externa becomes the egg sac filled with fertilized eggs.
