The moonfish of the genus Mene ("Crescent"), 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"[2]

Mene is a long-lived genus, with species found in marine sediments throughout the Cenozoic Era. The earliest accepted species, M. purdyi from the Paleocene of Peru, already 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 perciforme fishes, the affinity of Mene remains obscure. Anatomical and recent molecular studies strongly suggest a relationship with the pomfrets, dolphinfish, and the jacks. The genus' ancestry is particularly obscure, though, it is suggested that some Cretaceous acanthomorph fish, particularly Aipichthyoides of Cretaceous Lebanon, was close to Mene's ancestry.
