The scientific definition of fish is complex and can be a little confusing. Here is a much simplified definition. Fish are: Chordates, they have a backbone or notochord (cartilaginous support). Live almost entirely in water. Have apparatus to extract oxygen from water (gills). Have appendages without digits (fins). Are generally ectothermic.During the Ordovician and Silurian periods — from 490 to 410 million years ago — the world's oceans, lakes, and rivers were dominated by jawless fish, so named because they lacked lower jaws (and thus the ability to consume large prey).The evolution of fish included a shift from using the gills for filtering food to using them to absorb oxygen from water.
