Yes, planarian worms exhibit sleep-like behavior. Research has shown that they experience states of reduced activity and responsiveness, similar to sleep in more complex animals. During these periods, their metabolic rates decrease, and they exhibit changes in their neural activity, suggesting a form of restorative rest. This challenges the traditional notion that only more complex organisms exhibit sleep.

The planarian feeds on crustaceans, larvae, and small worms. To eat, it extends a long, tubular pharynx from its mouth. Through this tube it secretes digestive juice onto its prey, then sucks in bits of partly-digested food.

Planarian ventral nerve cords are bundles of nerve fibers located on the ventral (underside) surface of the planarian flatworm. These nerve cords coordinate the worm's movement, feeding, and response to stimuli. They are part of the planarian's simple nervous system that allows it to navigate its environment.
Planarian worms have the ability to regenerate into two new worms if cut in half because of their amazing regenerative capabilities. Each half is able to regenerate the missing parts, resulting in two separate worms.
