What is "zeidae"

The Zeidae (named after Zeus, the supreme god of Greek mythology) are a family of large, showy, deep-bodied zeiform marine fish—the "true dories". Found in the Atlantic, Indian, and Pacific Oceans, the family contains just six species in two genera. All species are important and highly regarded food fish supporting commercial fisheries, and some—such as the john dory (Zeus faber)—are enjoyed in large public aquaria. These fish are caught primarily by deep-sea trawling.

Several other families have members sharing the common name 'dory', some of which—i.e., those of genera Capromimus, Cyttomimus, and Cyttus—were once placed within the Zeidae. The first two genera are now found within the Zenionidae (or Zeniontidae), and the last genus has been given its own family, Cyttidae.
