The structures along the axis are a head, a body column, and a foot. As a consequence of its tissue dynamics, the animal has an extensive capacity for the morphallactic regeneration of head and foot. WebHydra has two main body layers, which makes it "diploblastic". The layers are separated by mesoglea, a gel-like substance. The outer layer is the epidermis, and the inner layer is called the gastrodermis, because it lines …
