Rasheedia Heptacanthi
''Rasheedia heptacanthi'' is a parasitic nematode in the genus ''Rasheedia''. The species is an intestinal parasite of the Cinnabar goatfish '' Parupeneus heptacanthus'' ( Mullidae) and '' Dentex fourmanoiri'' (Sparidae) off New Caledonia. The two species ''Rasheedia heptacanthi'' and '' Rasheedia novaecaledoniensis'', which both occur in New Caledonian waters, are mainly differentiated by the number of anterior protrusible oesophageal lobes (two in ''R. heptacanthi'' and four in ''R. novaecaledoniensis''), structure of the oesophagus and the lengths of their spicules Spicules are any of various small needle-like anatomical structures occurring in organisms Spicule may also refer to: *Spicule (sponge), small skeletal elements of sea sponges *Spicule (nematode), reproductive structures found in male nematodes ( ....

Nematodes Described In 2018
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant- parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over time.

Spicule (nematode Anatomy)
In nematodes, spicules, also known as copulatory spicules, are needle-like mating structures found only in males. Male nematodes may have one or two spicules which serve to open the vulva of females and facilitate the transmission of sperm, although sperm is not transferred directly by or through the spicules.Chitwood, B. G. & Chitwood, M. B. (1950). Introduction to Nematology (Vol. 1). Baltimore: Monumental Printing Co. (Function of spicule: pages 123-124) The 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 male ... is another organ of the nematode male copulatory system which guides the spicules during copulation.

Oesophagus
The esophagus (American English) or oesophagus (British English; both ), non-technically known also as the food pipe or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about long in adults, that travels behind the trachea and heart, passes through the diaphragm, and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word ''oesophagus'' is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω (phérō, “I carry”) + ἔφαγον (éphagon, “I ate”). The wall of the esophagus from the lumen outwards consists of mucosa, submucosa (connective tissue), layers of muscle fibers between layers of fibrous tissue, and an outer layer of connective tissue. The mucosa is a stratified squamous epithel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sparidae
The Sparidae are a family of fish in the order Perciformes, commonly called sea breams and porgies. The sheepshead, scup, and red seabream are species in this family. Most sparids are deep-bodied compressed fish with a small mouth separated by a broad space from the eye, a single dorsal fin with strong spines and soft rays, a short anal fin, long pointed pectoral fins and rather large firmly attached scales. They are found in shallow temperate and tropical waters and are bottom-dwelling carnivores. There are hermaphrodites in the Sparidae. Protogyny and protandry appear sporadically through this lineage of fish. Simultaneous hermaphrodites and bi-directional hermaphrodites do not appear as much since Sparidae are found in shallower waters. Species of fish that express a hermaphroditic condition usually "lack a genetic hardwire", therefore ecological factors play a role in sex determination. Most species possess grinding, molar-like teeth. Eating the head is known to cause hallu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mullidae
The goatfishes are perciform fish of the family Mullidae. The family is also sometimes referred to as the red mullets, which also refers more narrowly to the genus ''Mullus''. The family name and the English common name mullet derived from Latin ''mullus'', the red mullet; other than the red mullet and the striped red mullet or surmullet, the English word "mullet" generally refers to a different family of fish, the Mugilidae or gray mullets.''Oxford English Dictionary''''s.v.'' 'mullet'/ref> Description Goatfish are characterized by two chin barbels (or goatee), which contain chemosensory organs and are used to probe the sand or holes in the reef for food. Their bodies are deep and elongated, with forked tails and widely separated dorsal fins. The first dorsal fin has 6-8 spines; the second dorsal has one spine and 8-9 soft rays, shorter than anal fin. Spines in anal fin 1 or 2, with 5-8 soft rays. They have 24 vertebrae. Many goatfish are brightly colored. The largest specie ...

Rasheedia
''Rasheedia'' is a genus of nematodes in the order Spirurida. The nematode genus ''Bulbocephalus'' Rasheed, 1966 was found to be a homonym of ''Bulbocephalus'' Watson, 1916 (Apicomplexa, Stylocephalidae) and, therefore, a new name, ''Rasheedia'' n. nom., was proposed in 2018 to substitute it. The genus was named in honour of Suraiya Rasheed, "a well-known Pakistani fish parasitologist who was the first to describe these interesting nematodes". Species of ''Rasheedia'' are parasite of fish and include: * '' Rasheedia heptacanthi'' Moravec & Justine, 2018, a parasite of the Cinnabar goatfish '' Parupeneus heptacanthus'' (Mullidae) and ''Dentex fourmanoiri'' (Sparidae) * '' Rasheedia novaecaledoniensis'' Moravec & Justine, 2018, a parasite of the Indian goatfish '' Parupeneus indicus'' (Mullidae The goatfishes are perciform fish of the family Mullidae.
