there are three
There are only two layers.Endoderm layer and ectoderm layer.
Yes, flatworms belong to the phylum Platyhelminthes and do possess a mesoderm. They are acoelomate organisms, meaning they lack a true body cavity, but they have three germ layers: ectoderm, mesoderm, and endoderm. The mesoderm in flatworms contributes to the formation of muscles and other internal structures.
They have two layers the endoderm and ectoderm.
Flatworms are triploblastic organisms, meaning they have three germ layers (ectoderm, mesoderm, endoderm) that give rise to different tissues in their body. This allows them to have specialized structures like muscles and nerves. They have a solid body shape, lacking a body cavity or coelom.

facts about flatworms
Procotyla fluviatilis grows up to 20 millimeters long. but there are many speices of flatworms so i just found one
Yes flatworms are invertebrates
Flatworms are in the Platyhelminthesphylum.
Flatworms exhibit a bilateral symmetry and aacoelomate body plan, meaning they lack a body cavity and have a simplified organization with three tissue layers. In contrast, cnidarians have a radial symmetry and a body plan characterized by a gelatinous mesoglea layer, with two main tissue layers: the ectoderm and endoderm, and a central gastrovascular cavity. Additionally, cnidarians possess specialized cells called cnidocytes for capturing prey, which flatworms lack. Overall, these fundamental differences in symmetry, body organization, and tissue structure distinguish flatworms from cnidarians.
The scientific name for flatworms is Platyhelminthes.
