The invasive hammerhead worm species secretes a toxin also found in puffer fish that harm humans or pets, so be careful when killing hammerhead worms. If you see an invasive hammerhead worm, don't ...
Bipalium species are predatory.Some species prey on earthworms, while others may also feed on mollusks. [10] [11] These flatworms can track their prey. [12]When captured, earthworms begin to react to the attack, but the flatworm uses the muscles in its body, as well as sticky secretions, to attach itself to the earthworm to prevent escape.

[ 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 .
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 ...
Five species of invasive hammerhead worms — four in the genus Bipalium and one in Diversibipalium — are established in North America, said Bruce Snyder, an associate professor of biology at ...
Most adult individuals of B. adventitium are 5–8 cm (2.0–3.1 in) in length. The head is expanded and fan-shaped, being easily distinguishable from other common species of Bipalium, such as Bipalium kewense and Bipalium pennsylvanicum, because these have a head in the shape of a half moon. [1]
