Paracapillaria Xenentodoni
''Paracapillaria xenentodoni'' is a parasitic nematode present in the migratory fish '' Xenentodon cancila''. It has been observed in India. Description This species has a relatively large body size, with eggs reaching 0.040–0.049 × 0.021–0.026 mm. The structure of the male caudal extremity presents two wide, lobe-like, dorso-lateral caudal projections. It has a large spicule (0.236–0.374 mm) and a transversely wrinkled and non-spiny spicular sheath. Its stichosome has 30–40 stichocyte Stichocytes are glandular unicellular cells arranged in a row along the posterior portion of the oesophagus, each of which communicates by a single pore with the lumen of the oesophagus. They contain mitochondria, rough endoplasmic reticulum, abund ...s and it has a slightly elevated anterior vulval lip.

Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, 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 Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, 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 ...

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] |

Capillariidae
''Capillariidae'' is a family of parasitic nematodes. All its members are parasites in vertebrates when they are in their adult stage. Taxonomy The family Capillariidae was created by Railliet in 1915. It is accepted in the most recent classifications of the Nematoda,Hodda, M. 2011: Phylum Nematoda Cobb 1932. ''In'': Zhang, Z.-Q. (ed.) 2011: Animal biodiversity: an outline of higher-level classification and survey of taxonomic richness. ''Zootaxa'', 3148: 63–95. (paperback) (online editionPDF/ref> in which it is one of the members of the order Trichocephalida. However, ''Capillaria'' and closely related genera are sometimes included in the family Trichinellidae in other classifications. The taxonomy of the Capillariidae is disputed: according to different classifications, the family includes the single genus ''Capillaria'' or 22 different genera ('' Amphibiocapillaria, Aonchotheca, Baruscapillaria, Calodium, Capillaria, Capillostrongyloides, Crocodylocapillaria, Echino ...

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 ...

Xenentodon Cancila
''Xenentodon cancila'', the freshwater garfish, is a species of needlefish found in freshwater and brackish habitats in South and Southeast Asia. Common names As a reasonably popular aquarium fish, ''Xenentodon cancila'' has been traded under a variety of common names, including needlefish, silver needlefish, Asian freshwater needlefish, needlenose halfbeak, freshwater gar, needlenose gar and numerous others. While belonging to the same family as the marine needlefish known in Europe as gar or garpike, ''Belone belone'', these fish are much more distantly related to other fishes sometimes called gars (such as the North American gars and South American pike characins). In Assam it is locally known as Kokila. It is known as "Yonna (යොන්නා) or Habarali (හබරලි)" in Sri Lanka. Distribution The freshwater garfish is widely distributed across South and Southeast Asia from India and Sri Lanka to the Malaysian Peninsula. Morphology In common with other needlefish, ...

Stichosome
Stichosome (from Greek ''stichos (στίχος)'' = row; ''soma (σῶµα)'' = body) is a multicellular organ that is very prominent in some stages of nematodes and consists of a longitudinal series of glandular unicellular cells ( stichocytes) arranged in a row along the 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 ... that form the posterior esophageal glands. It opens into the esophageal lumen and apparently functions as a secretory gland and storage organ.Despommier DD, Müller M.

Stichocytes are glandular unicellular cells arranged in a row along the posterior portion of the oesophagus, each of which communicates by a single pore with the lumen of the oesophagus. They contain mitochondria, rough endoplasmic reticulum, abundant Golgi apparatuses, and usually 1 of 2 types of secretory granules, α-granules and β-granules, indicating secretory function Chitwood, B.
