Welcome to featured Wiki of the Day where we read the summary of the featured Wikipedia article every day.
The featured article for Saturday, 23 January 2021 is Gigantorhynchus.
Gigantorhynchus is a genus of thorny-headed worms, also known as spiny-headed worms, that parasitize marsupials, anteaters, and possibly baboons by attaching themselves to the intestines using their hook-covered proboscis. The life cycle includes an egg stage found in host feces, a cystacanth (larval) stage in an intermediate host such as termites, and an adult stage where cystacanths mature in the intestines of the host. This genus is characterized by a cylindrical proboscis with a crown of robust hooks at the apex followed by numerous small hooks on the rest of the proboscis, a long body with pseudosegmentation, filiform lemnisci, and ellipsoid testes. The largest specimen is a female G. ortizi with a length of around 240 millimetres (9.4 in) and a width of 2 millimetres (0.079 in). Genetic analysis on one species of Gigantorhynchus places it with the related genus Mediorhynchus in the family Gigantorhynchidae. Six species in this genus are distributed across Central and South America and possibly Zimbabwe. Infestation by a Gigantorhynchus species may cause partial obstructions of the intestines, severe lesions of the intestinal wall, and may lead to death.
