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.
A planarian is a type of flatworm belonging to the taxonomic class Turbellaria. They are typically found in freshwater environments and are known for their regenerative abilities and simple body structure.
The planarian is a type of flatworm that usually ranges from a few millimeters to a few centimeters in size, depending on the species. They have a simple, flattened body shape with a distinct head and tail end.
Planaria can come in various colors, including brown, black, and white. Some species of planaria may also have patterns or spots of other colors on their bodies.
The suffix meaning "one who feeds" is "-vore," as in "carnivore" (eats meat), "herbivore" (eats plants), or "omnivore" (eats both).
A planarian is a flatworm and is parasitic which means that it feeds off living things.
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.
Lake Pedder planarian was created in 1974.
A planarian can live without food for about a week.
A Planarian is an acoelomate, meaning they do not have a body cavity at all.
The two big dots on a planarian's head are its eyespots, which detect light and help the planarian navigate its environment. They are simple light-sensitive structures that allow the planarian to differentiate between light and dark. They also help the planarian avoid predators and find food.

No, a planarian is an example of a flatworm.
The pharynx in a planarian is located on the ventral side of the body, towards the front end. It is a muscular tube-like structure that extends out of the body to help the planarian feed on prey.
The phylum name for planarians is Platyhelminthes, which includes flatworms like the planarian. They are characterized by their flattened body shape and bilateral symmetry.
name one anatomical feature (other than symmetry) that distinguishes a planarian from a hydra.
