Unification Aspects:

As a group, the ray-finned fish add great ecological, commercial, aesthetic, recreational, and nutritional value. These fish provide essential nutrition for millions of people, are viewed in aquariums and underwater, are sought through sports fishing, and play a fundamental role in food chains, ensuring healthy ecosystems and controlling prey populations, including insects (Jonna 2004). Beyond this, their extraordinary diversity and geographic range—ubiquitous throughout fresh water and marine environments from the deep sea to the highest mountain streams (with some species even venturing outside of water) and with a spectacular array of colors, body forms, and behaviors—has added greatly to the human enjoyment of nature.

These values reflect the principle of bi-level functionality, whereby the various taxa not only advance their own individual function (survival, reproduction, maintenance), but also provide a function for the whole (ecosystem, humans).
