Dlium Javan broadhead planarian (Bipalium javanum)

Javan broadhead planarians walk above ground level by raising their heads and actively looking left, right and looking up using strong neck muscles. Move swiftly, track meander, climb to get through all obstacles or make a new path if the obstacle is too high.

Cacing palu track and prey on earthworms and mollusks. They use muscles and sticky secretions to attach themselves to prey to lock in. The head and ends of the body are wrapped around and continue to close the body to stop prey reactions.

They produce tetrodotoxins which are very strong as land invertebrates. Live in moist soils, mosses, dense vegetation and rocks. Grows fast with many adults in the rainy season in February, March and April at an altitude of 500-1500 m.
