Hammerhead worm

Description:

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 substrate. Several species are considered as invasive to the United States[3] and to Europe. Some studies have begun the investigation of the evolutionary ecology of these invasive planarians.

Habitat:

I spotted it in our backyard, it's common in rainy days and there are many varieties.

Notes:

This species have white band in tail as well as in face it have white orange shady, the body part is purely black that glows like a black mercury.
