The evolutionary tree shown here focuses on relationships among the ray-finned fishes (Actinopterygii, ACK-tih-NOP-tuh-RIJ-ee-eye). Click on the colored logos to read about evolutionary innovations and see lists of characteristics that evolved in different lineages. Note that this tree has been pruned to focus on certain groups of interest.
Click the red circular buttons to read stories of fish evolution.
Mouse over (or click on a touch screen) the green rectangular buttons to see the characteristics of fish lineages.
Mouse over (or click on a touch screen) the fish thumbnails for pronunciation of scientific name and photo.
