Arrowhead Worm

Bipalum kewense

Description:

A first for me. A predatory land planarian with a cosmopolitan distribution. It is sometimes referred to as a "Hammerhead Flatworm" due to its half-moon sharped head, but this name is also used to refer to other species in the subfamily Bipaliinae.

Habitat:

Native to the Indian subcontinent. Invasive in Florida where it kills native earthworms

Notes:

While some types of worms are edible, the Hammerhead worm is not among them. The planarian contains the potent neurotoxin tetrodotoxin. The tiffin found in pufferfish, the blue-ringed octopus, and rough-skinned newts, but not in a terrestrial invertebrate prior to its discovery in the Hammerhead worm.
