All remaining divisions or groups of animals are united under the name Metazoa for the following reasons: A careful consideration of their structure leads to the con- clusion that in all the body is of appreciable size, and that in each and every one certain portions or organs are specialized for the performance of certain functions neces- sary in the economy of the individual.

The special study of these constitutes, as already pointed out in the Introduction, the science of Physiology, which forms accordingly an important part of the study of Zoology, and a part to which frequent reference will be made in dealing with the structure of the various groups of animals. The various internal parts of an animal are supported and protected by the skin and the skeleton. The skin or in- tegument consists of a layer of cells — the epidermis — with,.

On the Walvis Bay line Protozoa and Metazoa were present only in very moderate numbers, their relative importance greatly increasing beyond the point where the rich diatom plankton declined. Yet again this transition zone was the only point where 'other plants' were noted.
