Question: are bass and grouper related?
Answer: Groupers are fish of any of a number of genera in the subfamily Epinephelinae of the family Serranidae, in the order Perciformes. Not all serranids are called 'groupers'; the family also includes the sea basses. The common name 'grouper' is usually given to fish in one of two large genera: Epinephelus and Mycteroperca.
