Huffmanela Hamo
''Huffmanela hamo'' is a parasitic nematode.Justine, J.-L. & Iwaki, T. 2014: ''Huffmanela hamo'' sp. n. (Nematoda: Trichosomoididae: Huffmanelinae) from the dagger-tooth pike conger ''Muraenesox cinereus'' off Japan. Folia Parasitologica, 61, 267–271Free PDF It has been observed in the muscles of the dagger-tooth pike conger ''Muraenesox cinereus'', a muraenesocid marine fish off Japan. Its life-cycle is unknown. Description The adults are unknown, only the eggs were described. The parasite was detected by the presence of small black spots, 1–2 mm in diameter, in the flesh (muscles) of fish; these black spots are accumulations of eggs. The eggs are 66–77 μm (mean 72 μm) in length and 33–38 μm (mean 35 μm) in width. The surface of the eggs is smooth and bears neither envelope nor filaments. The nematode was differentiated from other members of the genus ''Huffmanela'' by the dimensions of its eggs and the characteristics of their surface. It is the single ''H ...

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 ...

Muraenesox Cinereus
The daggertooth pike conger (''Muraenesox cinereus'') also known as the darkfin pike eel in Ozzyland, to distinguish it from the related pike-eel (''Muraenesox bagio''), is a species of eel in the pike conger family, Muraenesocidae. They primarily live on soft bottoms in marine and brackish waters down to a depth of , but may enter freshwater. They commonly grow to about in length, but may grow as long as . Daggertooth pike congers occur in the Red Sea, on the coast of the northern Indian Ocean, and in the West Pacific from Indochina to Japan. A single specimen was also reported in the Mediterranean Sea off Israel in 1982. Culinary uses Daggertooth pike conger is a major commercial species, with annual catches reaching about 350,000 tonnes in recent years. The spot reporting the largest landings was Taiwan Province of China. It is eaten in Japanese cuisine, where it is known as ''hamo'' ( ハモ, 鱧).

The Muraenesocidae, or pike congers, are a small family of marine eels found worldwide in tropical and subtropical seas. Some species are known to enter brackish water. Pike congers have cylindrical bodies, scaleless skin, narrow heads with large eyes, and strong teeth. Their dorsal fins start above the well-developed pectoral fins. These rather aggressive fish range from in length.

Huffmanela Hamo Eggs In Muraenesox Cinereus 1C
''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 other ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

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.

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 ...
