'Invasive species'
Its unknown which state Bipalium vagum are invasive to, but they are invasive to the United states. The Bipalium vagum "like other Bipaliums" are thought to have come over on horticultural plants. Most if not all invasive specias have becaome invasive because of humans. Very little is known about this species but its put a big dent in earth worms. The species has been killing earth worms and the population has decreased.The reason the species has survived was because of there "Immortality". The species is known to be immortal due to its body being able to regenerate and split into two.
Bipalium vagum is a land planarian in the subfamily Bipaliinae. It has been accidentally introduced in the United States, Bermuda and various islands in the Caribbean.[1][2][3]
Description
Bipalium vagum is a relatively small species of Bipalium, measuring about 25 mm (0.98 in) in length. The head varies from entirely black to dark brown with two black patches separated by a lighter ground color. The neck has a black collar interrupted only at the creeping sole. The dorsal color of the body is light brown and a broad black stripe runs longitudinally from the black collar to the posterior end. Laterally, there are two diffuse dark brown stripes.[1][3]
Feeding Habits
Differently from other invasive species of Bipalium, which feed on earthworms, B. vagum seems to feed exclusively on gastropods. As it seems to be spreading throughout the Caribbean and southern United States, there is certain concern on its possible impacts on the native gastropod fauna.[1][2]
