What is the X in X-mas?
any member of the order Elopiformes, a group of fishes considered to be the most primitive of bony fishes. The order contains about 12 species of marine and brackish water fishes, the best known of which are bonefish, tarpons, and ladyfishes. Most taxonomists recognize two living suborders of elopiforms: Elopoidei, which consists of two living families; and Albuloidei, which contains one living and one extinct family. A few elopiforms are prized gamefishes, but only the Pacific tarpon (or oxeye) is of economic importance as food, supporting a major fishery in Southeast Asia.
