Excerpt from Fresh-Water Biology With increase of the water body in Size or more especially in depth, new conditions are presented. The littoral region passes over insensibly into a deeper bottom region with its own biological series and to a free open-water area known as the limnetic region. The corresponding region in the ocean is designated the pelagic and this term is also used by some for the fresh-water area. The plants and animals in this region are characteristic; they constitute what is called the plankton, the floating life of the water. Such organisms remain suspended in water during their entire existence; they live and die on the wing. In the larger lakes the Shore zone loses in prominence whereas the pelagic and bottom regions gain in distinctness and relative importance.
