Huffmanela Branchialis
''Huffmanela branchialis'' is a parasitic nematode It has been observed on the gills of the fork-tailed threadfin bream ''Nemipterus furcosus'', a nemipterid marine fish off New Caledonia. Its eggs are released from the gill mucosa with the turnover of living tissues and immediately continue their life-cycle. Description The adults are unknown, only the eggs were described. The eggs are 45–52 micrometers in length and 23–30 micrometers in width, with thin shells. Each egg is enclosed in a thin membrane forming a spindle-shaped envelope 53–85 micrometers in length.

Parasitism
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes.

Nemipterid
Nemipteridae are a family of fishes within the order Perciformes. They are known as threadfin breams, whiptail breams and false snappers. They are found in tropical waters of the Indian and western Pacific Oceans. Most species are benthic carnivores, preying on smaller fishes, cephalopods, crustaceans and polychaetes; however, a few species eat plankton. Threadfin bream harbour parasites. A study conducted in New Caledonia has shown that the fork-tailed threadfin bream (''Nemipterus furcosus'') harboured 25 species of parasites, including nematodes, cestodes, digeneans, monogeneans, isopods, and copepod Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (inhabiting sea waters), some are benthos, benthic (living on the ocean floor) ...s. None of these parasites is transmitted to humans.

Gill
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill cham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mucosa
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated. Structure The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. Mucous membranes line the digestive, respiratory and reproductive trac ...

Nemipterus Furcosus JNC1121
''Nemipterus'' is a genus of fish in the family Nemipteridae. They are native to the Indian and Pacific Oceans, but now also occur in the Mediterranean Sea due to Lessepsian migration. Species There are currently 28 recognized species in this genus: * '' Nemipterus aurifilum'' ( J. D. Ogilby, 1910) (Yellow-lip thread-fin bream) * '' Nemipterus aurora'' B. C.

Huffmanela Filamentosa
''Huffmanela filamentosa'' is a parasitic nematode It has been observed on the gills of the lethrinid fish '' Gymnocranius oblongus'' and '' Gymnocranius grandoculis'' off New Caledonia.

Huffmanela Lata
''Huffmanela lata'' is a parasitic nematode.Justine, J.-L. 2005: ''Huffmanela lata'' n. sp. (Nematoda: Trichosomoididae: Huffmanelinae) from the shark ''Carcharhinus amblyrhynchos'' (Elasmobranchii: Carcharhinidae) off New Caledonia. Systematic Parasitology, 61, 181–184. It has been observed on the skin of the grey reef shark ''Carcharhinus amblyrhynchos'' off New Caledonia. This species has only been reported once in the scientific literature. Description The adults of ''Huffmanela lata'' are unknown, only the eggs were described. The eggs are 77–88 (mean 84) micrometers in length and 52–63 (mean 57) micrometers in width, with a thick (6–8 micrometers) shell, apparently spinose. Mobile larvae, 200–250 micrometers in length, were visible in the eggs. Biology As it is often the case for species of ''Huffmanela'', the species was found because the accumulation of its eggs produced a black spot; in this particular case, the black spot was on the skin of the shark, near t ...

Enoplea
Enoplea (enopleans) is a class, which with the classes SecernenteaTree of Life Web Project (ToL) (2002)Nematoda Version of January 1, 2002. Retrieved November 2, 2008. and Chromadorea make up the phylum Nematoda in current taxonomy. The Enoplea are considered to be a more ancestral group than the Chromadorea, and researchers have referred to its members as the "ancestrally diverged nematodes", compared to the "more recently diverged nematodes" of Chromadorea. Description The Enoplea are distinguished from the Chromadorea by a number of characteristics. The enoplean esophagus is cylindrical or "bottle-shaped", compared to the bulbous chromadorean esophagus. Enopleans have pocket-like amphids, while chromadoreans have amphids shaped like slits, pores, coils, or spirals. An enoplean is smooth or marked with fine lines, while a chromadorean may have rings, projections, or setae. The enoplean excretory system is simple, sometimes made up of a single cell, while chromadoreans have more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitic Nematodes Of Fish
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one".

There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), trophicallytransmitted parasitism (by being eaten), vector-transmitted parasitism, parasitoidism, and micropredation. One major axis of classification concerns invasiveness: an endoparasite lives inside the host's body; an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
