Etymology

Actinopterygii comes from Greek parts actino- ('ray') and -pterygii ('fin' or 'wing'), the same 'pter-' you see in pterodactyl meaning 'wing', so it literally means 'ray-finned'. That's why the name is used for the large group of fishes with thin bony 'rays' in their fins, like salmon and goldfish.
