Thus, the sponges (the lowest metazoans) are generally considered to be organized more on the cellular than on the tissue level of construction (Hyman 1940). Although sponges have an outer epithelial covering, the cells comp

This epidermal cell layer covers the entire body of the polyp from the tentacles to the pedal disc, forming a boundary with the external medium. The structure of the medusa is more complex; he

The cnidae of some anthozoans (sea anemones, corals, etc.) are perhaps the largest intracellular secretion products yet discovered, with some reaching a length of over 100 μm. Of the three major categories discovered to date (nematocysts, spirocysts and

In a fashion characteristic of cnidarians, the surface epithelium secretions of these animals shows a wide range of functions although they are produced by a tissue that

In the Heteronemertea it is predominantly composed of fibrous tissues with the dermal glands either embedded in it or forming a discrete peripheral zone, whereas in other taxa the dermis forms a thin to thick homogeneous hyaline structure,
