These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
The genus Anisakis was defined in 1845 [2] by Félix Dujardin as a subgenus of the genus Ascaris Linnaeus, 1758.Dujardin did not make explicit the etymology, but stated that the subgenus included the species in which the males have unequal spicules ("mâles ayant des spicules inégaux"); thus, the name Anisakis is based on anis-(Greek prefix for different) and akis (Greek for spine or spicule).
Free-living worm species do not live on land but instead live in marine or freshwater environments or underground by burrowing. In biology, "worm" refers to an obsolete taxon, Vermes, used by Carolus Linnaeus and Jean-Baptiste Lamarck for all non-arthropod invertebrate animals, now seen to be paraphyletic. The name stems from the Old English ...
Enchytraeus buchholzi/Grindal worms are cultured by aquarists as a fish food, often on a bed of ground coconut shells, or coir, with oatmeal. They are used for conditioning tropical fish before spawning, or for young fast-growing fish. In laboratory testing, Enchytraeus buchholzi were kept in an incubator at 15 ± 2 °C. Water loss and food ...
As the name implies, it causes severe anemia of infected fish. Unlike mammals, the red blood cells of fish have DNA, and can become infected with viruses. The fish develop pale gills, and may swim close to the water surface, gulping for air. However, the disease can also develop without the fish showing any external signs of illness, the fish ...
Dozens of captive animal species have been found infected or proven able to be experimentally infected with SARS-CoV-2, the virus that causes COVID-19. The virus has also been found in over a dozen wild animal species. Most animal species that can get the virus have not been proven to be able to spread it back to humans.
The Global Forum on Food Security and Nutrition suggests edible insects as a solution to the “rising costs of animal protein, food and feed insecurity, environmental pressures, population growth ...
The peculiar genus Mesenchytraeus is known as "ice worms", as they spend the majority of their lives within glaciers, only rising to the surface at certain points in the summer. [ 2 ] [ 3 ] Enchytraeidae also includes the Grindal worm ( Enchytraeus buchholzi ), which is commercially bred as aquarium fish food.
