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. [2] Mermithidae are confused with the horsehair worms of the phylum Nematomorpha that have a similar life history and appearance. Mermithids are parasites, mainly of arthropods ...
Litomosoides scotti is a parasitic nematode in the genus Litomosoides. First described in 1973, it infects the marsh rice rat (Oryzomys palustris) and is known from a saltwater marsh at Cedar Key, Florida. [1]
The ctinidia lie mainly within the branchial siphon, through which the animal pumps the water that passes over the gills. The two siphons are very long and protrude from the posterior end of the animal. Where they leave the end of the main part of the body, the siphons pass between a pair of calcareous plates called pallets.
Marine worms are known to inhabit many different environments, having been found in both fresh and saltwater habitats globally. [citation needed] Some marine worms are tube worms, of which the giant tube worm lives in waters near underwater volcanoes and can withstand temperatures up to 90 °C (194 °F). They share this space with fellow ...
Halicephalobus mephisto is a species of nematode, among a number of other roundworms, discovered by geoscientists Gaetan Borgonie and Tullis Onstott in 2011. It was detected in ore recovered from deep rock fracture water in several gold mines in South Africa 0.9 km (0.56 mi), 1.3 km (0.81 mi), and 3.6 km (2.2 mi) under the surface of the Earth. [1]
The newly hatched nematode is about 0.24 millimetres long; by day 37 it has reached about 5 centimetres. The nematodes grow more rapidly and attain larger sizes in larger insect hosts. More females occur in larger hosts, as well. The nematode is still a juvenile when it emerges from the host insect, and finishes its development in the soil.
The free-living nematode Panagrellus redivivus (sour paste nematode, [2] or beer mat nematode from its occurrence in constantly moist felt beer mats), [1] is known to many aquarium enthusiasts and fish keepers as the microworm. It is a tiny roundworm used as the first food for larger kinds of newly-hatched fish, such as larval common carp. [3]
