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 ...

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. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted paras ...

Carcharhinus Amblyrhynchos
The grey reef shark (''Carcharhinus amblyrhynchos'', sometimes misspelled ''amblyrhynchus'' or ''amblyrhinchos'') is a species of requiem shark, in the family Carcharhinidae. One of the most common reef sharks in the Indo-Pacific, it is found as far east as Easter Island and as far west as South Africa. This species is most often seen in shallow water near the drop-offs of coral reefs. It has the typical "reef shark" shape, with a broad, round snout and large eyes. It can be distinguished from similar species by the plain or white-tipped first dorsal fin, the dark tips on the other fins, the broad, black rear margin on the tail fin, and the lack of a ridge between the dorsal fins. Most individuals are less than long. The grey reef shark is a fast-swimming, agile predator that feeds primarily on free-swimming bony fishes and cephalopods. Its aggressive demeanor enables it to dominate many other shark species on the reef, despite its moderate size. Many grey reef sharks have a ...

Huffmanela
''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. 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 develop after being laid. Eggs usually occur as masses in the tissues of the hosts, occurring frequently as conspicuous black spots in the flesh or oth ...

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.

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, 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.

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.
