Fragmentation in planarians refers to their ability to regenerate lost body parts after being cut into pieces. This process allows them to develop into new individuals from fragments, with each piece capable of regenerating a complete organism. Planarians possess a high concentration of pluripotent stem cells, which play a crucial role in regeneration by differentiating into various cell types needed for tissue and organ formation. This remarkable ability makes planarians a popular subject for studies on regeneration and developmental Biology.

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.
Planarians, a type of flatworm belonging to the class Turbellaria, are known to undergo fragmentation as a means of asexual reproduction. When a planarian is cut into pieces, each fragment can regenerate into a complete organism, provided that certain body parts, such as a portion of the head and some regenerative cells, are present. This remarkable regenerative ability allows them to reproduce rapidly and adapt to their environments.
A planarian is a flatworm and is parasitic which means that it feeds off living things.
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.
