The **mirrorwing flyingfish** (*Hirundichthys speculiger*) is a flying fish of the [family](/source/Family_(taxonomy)) [Exocoetidae](/source/Exocoetidae). It was first described by the [French](/source/French_people) [zoologist](/source/Zoologist), [Achille Valenciennes](/source/Achille_Valenciennes) in a 22-[volume](/source/Volume_(bibliography)) work titled *Histoire naturelle des poissons* (*Natural History of Fishes*), which was a collaboration with [Georges Cuvier](/source/Georges_Cuvier).

## Description

Mirrorwing flyingfish have 10-12 soft rays on their [dorsal fins](/source/Dorsal_fin) and 11-13 rays on their [anal fins](/source/Anal_fin).[1] Their bodies are generally dark, with blue on top and silver-white on bottom.[1] The dorsal and [caudal fins](/source/Caudal_fin) are both grayish, while the other fins are [hyaline](/source/Hyaline).[2] Juveniles have more elongated bodies and mottled fins.[2] Adults can grow up to 30 cm (1 ft) long,[3] but usually they reach about 24 cm.[4]

## Distribution and habitat

Mirrorwing flyingfish are known from warm surface waters worldwide,[5] but are most common in tropical and temperate waters. In the [Atlantic Ocean](/source/Atlantic_Ocean), they are common to the tropical areas in the east and all along the [North](/source/North_America) and [South American](/source/South_American) [coasts](/source/Coast),[3] but are uncommon in the [Gulf of Guinea](/source/Gulf_of_Guinea),[6] [Caribbean Sea](/source/Caribbean_Sea), and [Gulf of Mexico](/source/Gulf_of_Mexico).[7] They are curiously absent from the [Benguela Current](/source/Benguela_Current).[5] In the [Indian Ocean](/source/Indian_Ocean), mirrorwing are known from [south Africa](/source/South_Africa),[2] [Mauritius](/source/Mauritius), [Rodrigues](/source/Rodrigues), the [Maldives](/source/Maldives),[8] and the [Chagos Archipelago](/source/Chagos_Archipelago).[9] In the [Pacific Ocean](/source/Pacific_Ocean), they are known from most regions save the seas of [southeast Asia](/source/Southeast_Asia).[5] Mirrorwing flyingfish [spawn](/source/Spawn_(biology)) year round in the offshore waters where they normally live attaching their [eggs](/source/Egg_(biology)) to floating debris in masses.[10] Mirrorwing eggs use a series of filaments to achieve this attachment, the arrangement of which can be used to identify them as mirrorwing eggs.[10]
