Can flatworms kill humans?
Not only are they an invasive species that can cause real environmental damage, but they also are known to carry a parasite called rat lungworm that can cause a form of meningitis in humans. Besides that, this flatworm produces toxic secretions that may trigger an allergic reaction in some people.

Are Bipalium poisonous?
Toxicity. Bipalium kewense is one of the few terrestrial invertebrates known to produce tetrodotoxin, a neurotoxin that results in paralysis. It is possible that the toxin aids the planarian in subduing its prey as well as in protecting it against predators.
Do Planarians feel pain?
The Gallio research team found that planarians possess their own variant of an already famous receptor, TRPA1. TRPA1 is best known as the “wasabi receptor” in humans and as a sensor for environmental irritants giving rise to the sensation of pain and itch.

Planarians often have an ear-like projection on each side of their body beside their eyes. These projections are called auricles. They don’t play a role in hearing as their name might suggest but instead contain chemoreceptors to detect chemicals. They are also sensitive to touch.
How do Planaria take in food to their body?
Planaria eat living or dead small animals that they suck up with their muscular mouths. Food passes from the mouth through the pharynx into the intestines where it is digested by the cells lining the intestines. Then its nutrients diffuse to the rest of the planaria.
