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 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 ...
To date, more than 3,000 sightings in southeastern states of just one invasive hammerhead species — Bipalium kewense — have been shared to the citizen scientist database iNaturalist.But 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 Turbellaria are one of the traditional sub-divisions of the phylum Platyhelminthes (flatworms), and include all the sub-groups that are not exclusively parasitic.There are about 4,500 species, which range from 1 mm (0.039 in) to large freshwater forms more than 500 mm (20 in) long [3] or terrestrial species like Bipalium kewense which can reach 600 mm (24 in) in length.
It is superficially similar to Bipalium kewense, which is even more widespread in the world, but can be easily distinguished by the marking on its head (D. multilineatum has an 'exclamation point' on the head).
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 ...
