The definition of a Planarian is "any of various free-swimming, mostly freshwater flatworms of the class Turbellaria, having an undulating or sluglike motion: popular in laboratory studies for the ability to regenerate lost parts." This means that it can, if any body parts are chopped off, regrow them. In junior high we sliced it's head down the middle and it regrew two heads in a matter of weeks. Cool, but really disgusting. It is a worm-like animal. The definition of animal is "any such living thing other than a human being." So in conclusion, according to the definition of animal, a Planarian is an animal, but a very strange one.
A planarian is a type of flatworm that is typically found in freshwater environments. They are known for their regenerative abilities and their simple anatomy, which includes a centralized nervous system and light-sensitive eyespots. Planarians are often used in scientific research for studies on regeneration and basic biological processes.
Planaria are invertebrates, they do not have an internal skeleton with a backbone.

What are the two big dots on a planarian's head?
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.
