Is it similar to the case of the aquatic habit of the larvae of many insects, such as gnats and mayflies, which is believed to be quite secondary ? There is most to be said for the view that the pelagic phase of some shore-animals is secondary. The larvae are often highly speciahzed in relation to open-sea life, and not the least like ancestral forms. In certaiu cases the first view may be enter- tained. Parental Care.—Returning to the avoidance of infantile mortality, another method of life-saving is to increase parental care and nurture; and the shore is rich in illus-.
