Philometra Ocularis
''Philometra'' is a genus of nematodes, which are parasites of marine and freshwater fishes. The genus was erected by Oronzio Gabriele Costa in 1845. Species in this genus are worldwide. They parasitize the body cavities, tissues and ovaries of both marine and freshwater fishes. When still in the larval stages, these worms move to the body cavities or subcutaneous tissues in the host. This migration can cause damage to skeletal joints, result in internal bleeding, and inflame visceral organs. Emaciation and lowered growth rates may result from this. Infestation produces nodules under the skin. When the worms are in the adult or juvenile stage, these nodules may be visible between the rays of the fins or may cause the scales to raise up. Larger nodules may be the result of gravid females which may rupture the skin surface. Once ruptured, the female disintegrates. This allows the release of the live larvae into the water. This wound on the fish then heals, leaving almost no scarrin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philometra Fasciati
''Philometra fasciati'' is a species of parasitic nematode of fishes, first found off New Caledonia in the South Pacific, in the gonads '' Epinephelus fasciatus''. This species is characterized mainly by: length of spicules and length and structure of its gubernaculum The paired gubernacula (from Ancient Greek κυβερνάω = pilot, steer) also called the caudal genital ligament, are embryonic structures which begin as undifferentiated mesenchyme attaching to the caudal end of the gonads (testes in mal ...; structure of male caudal end; body size; location in host and types of hosts.
