Hammerhead Flatworm (Bipalium kewense)

Scaled collection of drawings of Hammerhead Flatworm in various poses

The Hammerhead Flatworm (Bipalium) is a predatory land planarian named after the distinctive shape of their head region. As their native habitat were regions of Southeast Asia, they like environments that are hot and humid, so they do well in greenhouses and tropical and subtropical areas. They like to be out of the sun under leaf litter, rocks and logs, and shrubs. The Hammerhead Flatworm has a half-moon shaped head; it is usually light colored with one to five dark dorsal stripes and a dark collar. They are a known predator of earthworms, but they may feed on other organisms.

The Hammerhead Flatworm has an overall length between 7.87”-15.75” (20-40 cm) and diameter of .12”-.2” (3-5 mm).
