It takes about two weeks for a planarian to regenerate.
Planaria are adapted to be free-living through their ability to regenerate lost body parts, their capacity to survive in various aquatic environments, and their well-developed sensory system that helps them navigate and find food in their surroundings. Additionally, their flat body shape and cilia help them move efficiently and effectively in their environment.
No, planaria are not segmented. They are flatworms that have a simple body plan with bilateral symmetry. They do not have true segments like some other invertebrates.
Planarian is a regenerating non-parasitic flatworm. Most planarian are striped or lined and some of the large type has bright colors.
A sea star is an animal that can regenerate from a separated piece of the parent, a process known as asexual reproduction. If a sea star is cut into pieces, each piece has the potential to grow into a new sea star.
These are Flatworms, and belong to the Pyllum Platyhelminthes. platy = flat, helminthes = worms. Can be obtained with a meat bait in a jar put in a stream. A couple of cm long. These guys have discovered sex, and have eyes, brain. But they consume their prey by wrapping themselves round it and 'sucking up' - after digestive fluids no doubt.
Planaria
Usually a planaria regeneration experiment involves cutting the planaria into different parts. The head can be separated from the tail or the planaria can be cut lengthwise, etc. After cutting the planaria, it will be observed for few days noting how the organism regenerate its lost body parts.

They live for many weeks.

It will take about 3 to 6 months for fingernails to regenerate or regrow completely. The growth rate will depend on the age of the person.
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.
1 month
Both would be appropriate, as long as the planaria can reach that food source.
The planaria class is Turbellaria
Planaria are small creatures that live in fresh water. They have flat bodies and can regenerate lost body parts. They can also be conditioned to respond to stimuli.

sp refers to a planaria where the actual species is undetermined...or sometimes because several species of planaria have similar appearance or behavior and have been used in a study.
