Coelenterata

Definition and stakes

Marcus Hartog,  The Cambridge natural history, Vol… (1906)

“ In this Class of Coelenterata two types of body-form may be found. In such a genus as Obelia there is a fixed branching colony of zooids, and each zooid consists of a simple tubular body-wall composed of the two layers of cells, the ectoderm and the {250}endoderm (Fig. 125) , terminating distally in a conical mound—the "hypostome"—which is perforated by the mouth and surrounded by a crown of tentacles. This fixed colony, the "hydrosome," feeds and increases in size by gemmation, but does not produce sexual cells. ”

“ Their first words, as they sat among the bales, were words of grief at the sorrow and anxiety of their relations, who would search high and low through the woods, until at last they gave them up as dead. "Alca will give them hope and courage," said Coelred. "She will know that we are together, and she knows that we shall return. For we are to die in battle fighting for a righteous cause, and that cannot be anywhere but in England. She is praying now that the gods will watch over us, and her prayers are ever answered." ”

“ There can be but little question of the propriety of including Ctenophora among the Coelentera. The undivided coelenteron (gastro-vascular system) which constitutes the sole cavity of the body, the largely radial symmetry, the presence of endodermal generative organs on the coelenteric canals, the subepithelial nerve-plexus, the mesogloea-like matrix of the body—all these features indicate affinity to other Coelentera, but, as has been stated in the article under that title, the relation is by no means close. ”
