Another aspect of cnidarians is that all cnidarians have two layers of living tissue. These two layers are always separated by a gelatinous layer called mesoglea. The first layer of living tissue is known as the dermis, and the second layer is know as the gastordermis.
While they lack organs, Cnidarians have a net of sensory nerve cells, tentacles or oral arms, gonads that produce reproductive cells, and a gastrovascular cavity, where digestion takes place. The cavity opening is also used to expel waste and release reproductive cells.hile they lack organs, Cnidarians have a net of sensory nerve cells, tentacles or oral arms, gonads that produce reproductive cells, and a gastrovascular cavity, where digestion takes place.
