Bipalium is a genus of large predatory land planarians. They are often loosely called " hammerhead worms " or " broadhead planarians " because of the distinctive shape of their head region. Land planarians are unique in that they possess a "creeping sole", a highly ciliated region on the ventral epidermis that helps them to creep over the ...
Several hammerhead flatworms have become invasive, the most famous being Bipalium kewense, now in many countries in all continents except the Antarctica.A 2022 study used occurrence records from online databases, including iNaturalist, and climatic and soil variable to model the potential distribution of five species of hammerhead flatworms, namely B. kewense, B. adventitium, B ...
The Bischler–Napieralski reaction is an intramolecular electrophilic aromatic substitution reaction that allows for the cyclization of β-arylethylamides or β-arylethylcarbamates. It was first discovered in 1893 by August Bischler and Bernard Napieralski [ de ] , in affiliation with Basel Chemical Works and the University of Zurich .
Bipalium kewense, also known as the shovel-headed garden worm, is a species of large predatory land planarian with a cosmopolitan distribution. [ 1 ] [ 2 ] It is sometimes referred to as a "hammerhead flatworm" due to its half-moon-shaped head, but this name is also used to refer to other species in the subfamily Bipaliinae .
Bipalium nobile is a very long planarian, reaching up to 1 m (3.3 ft) in length. As in other species of Bipalium, the head is expanded, being fan-shaped in live animals.. The dorsal color is pale yellowish brown with five blackish brown longitudinal strip
Bipalium fuscatum is a species of land planarian first described by William Stimpson in 1857. It has been found in Japan, Indonesia, and in parts of continental South Asia and East Asia such as China, India and Korea. [1] [2] [3] This hammerhead flatworm may be able to survive for days in a human lung as a pseudoparasite. [4]
Differently from Bipalium kewense, which usually reproduces asexually by fission, Bipalium adventitium more commonly reproduces sexually. It is suggested that it has only one breeding season per year. [2] As in most land planarians, mating occurs by internal fertilization when two individuals meet. The eggs are deposited in egg capsules and ...
