They belong to the phyla Platyhelminthes, along with the flatworms. Members in this phyla are acoelomates.
The three systems that developed in the mesoderm of the planarians are ectoderm, mesoderm, and endoderm. They are usually described as the three germ layers.
Planarians are free-living flatworms, flukes are parasitic flatworms that infect various host animals, and leeches are blood-feeding segmented worms.
Planarians are multicellular organisms with specialized cells and tissues. They have a defined body plan with distinct organs and structures. Planarians exhibit movement and respond to external stimuli. They consume food and have a digestive system. Planarians can reproduce sexually or asexually, exhibiting typical animal reproductive capabilities.

Planarians have bilateral symmetry.
There are three main types of worms: annelids (segmented worms), nematodes (roundworms), and platyhelminthes (flatworms). Annelids include earthworms and leeches, while nematodes encompass many species like Ascaris and Caenorhabditis elegans. Platyhelminthes feature species such as planarians and tapeworms. Each type plays a unique role in ecosystems and has distinct biological characteristics.
Planarians are neither parasitic or segmented. They are flatworms.
Yes, planarians are non-parasitic flatworms
The structures that enable planarians to expel liquid waste are normally pores. The pores are found on the dorsal surface of the planarians.
annelids

Planarians move by expanding and contracting their bodies as they grip a surface.
Annelids have an anus
