Resembling or relating to fish of the sunfish family (Centrarchidae); having characteristics similar to centrarchid fish.
From Centrarchidae + -oid (suffix meaning 'resembling' or 'like'). The -oid suffix comes from Greek -oeidēs, widely used in scientific nomenclature.
Scientists use -oid words all the time in biology: humanoid (human-like), android (man-like), asteroid (star-like)—it's a way to say 'resembles this thing but isn't exactly this thing.'
