Mene
The moonfish of the genus ''Mene'', the sole extant genus of the family Menidae, are disk-shaped fish which bear a vague resemblance to gourami, thanks to their thread-like pelvic fins. Today, the genus is represented only by ''Mene maculata'' of the Indo-Pacific, where it is a popular food fish, especially in the Philippines, where it is known as ''bilong-bilong'', ''chabita'', ''hiwas'' or ''tahas''.〔Small-scale fisheries of San Miguel Bay, Philippines: options for management and research.

As a genus, ''Mene'' has a long fossil history, with species found in marine sediments throughout the Cenozoic Era. The earliest accepted species, ''M. purdyi'' from the Paleocene of Peru, resemble later species, such as ''M. rhombea'' of the Monte Bolca lagerstätte, and even the living species, ''M. maculata''. Experts remain undecided whether the Tunisian species, ''M. phosphatica'' is from the Lower Paleocene, thus making it older than ''M. purdyi'', or whether it is from the Ypresian epoch of the Eocene. Almost all of the species are known primarily from the Paleogene; the Neogene record is rather sparse, if not totally nonexistent, with some otoliths found in Miocene strata, and no whole or even partial specimens known from Pliocene or Pleistocene strata.
Beyond being a group of perciform fish, the affinity of ''Mene'' remains obscure. Anatomical and recent molecular studies strongly suggest a relationship with the pomfrets, dolphinfishes, and the jacks.
