Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Danish Ingolf-Expedition, Vol. 6: 3. Porifera, (Part III.) Desmacidonidae (Pars.) The skeleton. The dermal skeleton; the skeleton formed by the dermal spicules is not much developed, it consists of larger or smaller bundles of dermal spicules lying in the membrane, partly horizontally, partly more or less erect in the somewhat thick dermis; besides the bundles more scattered and single spicules may also occur, but they are on the whole scarce, and large parts of the membrane may be seen without dermal spicules. At the base of the papilla they are present in greater numbers, and from here they stretch out in the wall of the papilla and form the skeleton of the papilla as mentioned above. The main skeleton is a rather diffuse and irregular, multispicular reticulation in which primary and secondary fibres cannot be discerned; also single spicules are in many places seen to contribute to the skeleton. In the points of union is seen a distinct and rather rich amount of spongin which may also sometimes be seen to continue along the fibres.
