There have traditionally been strong ties between physiology and ecology and between ecology and systematics. Although the connection between physiology and systematics has not been adequately realized, there are important reasons to strengthen it. Much of physiology has been based on the comparative method, which implies a knowledge of evolutionary relationships. Systematics, on the other hand, relies on the distribution of characteristics among groups of organisms, and should include characteristics of their lifestyles, including performance. Lifestyle characteristics, which are studied by physiologists, ecologists, or behavioral scientists, may be comparatively recent adaptations or may be constrained by evolution similarly to the morphological characters traditionally studied by systematists. Working together, these disciplines can provide better explanations of adaptations and evolutionary constraints about which not much is known for the great majority of cephalopod taxa.
