Parasitism
Parasitism is a close relationship between species, where one organism, the parasite, lives (at least some of the time) 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 characterised parasites' way of feeding 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 honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. 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: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nemipterid
Nemipteridae, the threadfin breams, whiptail breams, or Sultan Ibrahim, is a family of marine ray-finned fishes belonging to the order Spariformes. These fishes are found in the Indo-West Pacific region. Taxonomy Nemipteridae was first proposed as a family in 1913 by the English ichthyologist Charles Tate Regan with the genera '' Heterognathodes'', ''Nemipterus'' and ''Scolopsis'' included in the family. Traditionally this family has been classified within the Perciformes, as part of the group of families some authorities called the "Sparoid lineage", this included the families Centrarchidae, Nemipteridae, Lethrinidae and Sparidae. Molecular phylogenetics Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships.

New Caledonia
New Caledonia ( ; ) is a group of islands in the southwest Pacific Ocean, southwest of Vanuatu and east of Australia. Located from Metropolitan France, it forms a Overseas France#Sui generis collectivity, ''sui generis'' collectivity of the French Republic, a legal status unique in overseas France, and is enshrined in a dedicated chapter of the French Constitution. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre (New Caledonia), Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines (New Caledonia), Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre , a nickname also used more generally for the entire New Caledonia. Kanak people#Agitation for independence, Pro-independence Kanak parties use the name (''pron.'' ) to refer to New Caledonia, a term coined in the 1980s from the ethnic name of the indi ...

Gill
A gill () is a respiration organ, respiratory organ that many aquatic ecosystem, 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 (: branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamella (surface anatomy), lamellae (folds) contain blood or Coelom#Coelomic fluid, 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 Mollusc, molluscs, crustaceans, insects, fish, a ...

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 rep ...

Nemipterus Furcosus JNC1121
''Nemipterus'' is a genus of marine ray-finned fishes belonging to the family Nemipteridae, the threadfin and whiptail breams. These fishes are found in the Indian and Pacific Oceans, but now also occur in the Mediterranean Sea due to Lessepsian migration. Taxonomy ''Nemipterus'' was first proposed as a monospecific genus in 1839 by the English zoologist William Swainson with ''Dentex filamentosus'', a species described by Achille Valenciennes in 1830 from "Suriname", as its only species. Valenciennes' ''D. filamentosus'' has since been determined to be a subjectively invalid name and the valid name is ''Dentex nematophorus'' which had been described by Pieter Bleeker from Padang in Sumatra in 1854. The 5th edition of ''Fishes of the World'' classifies ''Nemipterus'' within the family Nemipteridae which it places in the order Spariformes. Etymology ''Nemipterus'' is a compound of ''nematos'', meaning "thread", and ''pterus'', which means "fin", and this is a reference to the fil ...

Huffmanela Filamentosa
''Huffmanela'' is a genus of parasitic nematodes, belonging to the family Trichosomoididae. Morphology As other nematodes, species of ''Huffmanela'' are elongate and vermiform. They are especially thin and small. The male is smaller than the female. The stichosome is composed of a single row of stichocytes (glandular cells). The advances eggs contain larvae and have strongly pigmented, dark, often conspicuously thick walls comprising three layers, and polar plugs. The structure of the egg of ''Huffmanela'' nematodes has been redescribed in great detail in 2023, with a new anatomical and terminological framework. Biology Nematodes of the genus ''Huffmanela'' are all parasites of fishes. They infect various tissues (skin, mucosa, musculature, swimbladder wall, intestine wall, and even within the bones) of elasmobranchs (sharks) and bony fishes. The life cycle of the marine species is not known. Females lay eggs in the host's tissues at a very early stage and eggs continue to ...

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 ...

Huffmanela Ossicola
''Huffmanela ossicola'' is a parasitic nematode. It has been observed in the branchial arch bone and the spinal cord bone (as well as others) of the labrid marine fishes ''Bodianus loxozonus'', ''Bodianus busellatus'' and '' Bodianus perditio'' caught off New Caledonia. This is the first species of ''Huffmanela'' reported from bone tissue. Its eggs are only available for the continuation of the life-cycle after the host's death. Description The adults are unknown; only the eggs were described. The eggs are large, 72–88 micrometers in length and 32–40 micrometers in width, with a thick shell.

Enoplea
Enoplea (enopleans) is a Class (biology), 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 Nematode, Nematoda in current taxonomy (biology), 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 ...
