Agfa is the only genus in the parasitic nematode family Agfidae. There are only three known species: Agfa flexilis, A. morandi and A. tauricus. They are all obligate parasites in terrestrial gastropods.
Isopoda is an order of crustacean, which includes woodlice and their relatives. Members of this group are called Isopods and include both terrestrial and aquatic species. All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration. Females brood their young in a pouch under their thorax.
Anisakis is a genus of parasitic nematodes that have life cycles involving fish and marine mammals. They are infective to humans and cause anisakiasis. People who produce immunoglobulin E in response to this parasite may subsequently have an allergic reaction, including anaphylaxis, after eating fish infected with Anisakis species.
Secernentea was a class of nematodes in the Classical Phylogeny System and is no longer in use. This morphological-based classification system has been replaced by the Modern Phylogeny system, where taxonomy assignment is based on small subunit ribosomal DNA.
Heterorhabditis is a genus of nematodes belonging to the order Rhabditida. All species of this genus are obligate parasites of insects, and some are used as biological control agents for the control of pest insects.
Archiacanthocephala is a class within the phylum of Acanthocephala. They are parasitic worms that attach themselves to the intestinal wall of terrestrial vertebrates, including humans. They are characterised by the body wall and the lemnisci, which have nuclei that divide without spindle formation, or the appearance of chromosomes, or it has a few amoebae-like giant nuclei. Typically, there are eight separate cement glands in the male, which is one of the few ways to distinguish the dorsal and ventral sides of these organisms.
Limax cinereoniger, the ash-black slug is a large species of air-breathing land slug in the terrestrial pulmonate gastropod mollusc family Limacidae, the keelback slugs. This is the largest land slug species in the world.
Acanthocephalus is a genus of parasitic worms. One of the species in this genus is Acanthocephalus anguillae, a fish parasite. Acanthocephalans are also found in humans and primates, causing a common zoonotic infection called "human acanthocephaliasis". While pathogens can be transferred among animals and humans, the main source of human acanthocephaliasis is the diet of infected raw fish and insects. Because they are lacking circulatory, respiratory, and digestive systems, Acanthocephalus are exceptionally well-adapted to a symbiotrophic existence.
Mermithidae is a family of nematode worms that are endoparasites in arthropods. As early as 1877, Mermithidae was listed as one of nine subdivisions of the Nematoidea. Mermithidae are confused with the horsehair worms of the phylum Nematomorpha that have a similar life history and appearance.
Agfa flexilis is a species of parasitic nematodes.
Angiostomatidae is a family of parasitic nematodes.
Angiostoma is a genus of parasitic nematodes in the family Angiostomatidae.
Hematodinium is a genus of dinoflagellates. Species in this genus, such as Hematodinium perezi, the type species, are internal parasites of the hemolymph of crustaceans such as the Atlantic blue crab and Norway lobster. Species in the genus are economically damaging to commercial crab fisheries, including causing bitter crab disease in the large Tanner or snow crab fisheries of the Bering Sea.
Arhythmacanthidae is a family of parasitic worms from the order Echinorhynchida.
Pterygodermatites is a genus of parasitic nematodes in the family Rictulariidae. Their life-cycle is complex. Species include:
Phasmarhabditis hermaphrodita is a facultative parasitic nematode that can kill slugs and snails. It belongs to the family Rhabditidae, the same family as Caenorhabditis elegans.
Opecoelidae is a family of trematodes. It is the largest digenean family with over 90 genera and nearly 900 species, almost solely found in marine and freshwater teleost fishes. It was considered by Bray et al. to belong in the superfamily Opecoeloidea Ozaki, 1925 or the Brachycladioidea Odhner, 1905.
Heterorhabditis megidis is a species of nematodes in the genus Heterorhabditis. All species of this genus are obligate parasites of insects, and some are used as biological control agents for the control of pest insects.
Cucullanus bulbosus is a species of parasitic nematodes. It is an endoparasite of carangid fishes.
Traklosia is a genus of nematodes. The genus was originally circumscribed in 1961 under the name Robertia; L. Travassos and G. R. Kloss created this genus for their newly-described species R. leiperi. The nomen novum, Traklosia, was created for this genus in 2015 — Robertia was an invalid name due to a senior homonym. It consists of three species found in Brazil and Cuba, and they are parasites of millipedes.
Physalopteridae is a family of spirurian nematodes, which belongs to the superfamily Physalopteroidea. Like all nematodes, they have neither a circulatory nor a respiratory system.
