棲地
(

)
由The Fish Database of Taiwan提供
洄游性魚種，生活於近海或淺海域之表水層，並不分布於開放水域。受驚嚇時會利用其特化的胸鰭躍出水面作長距離的滑翔。主要以橈腳類及端腳類等浮游生物為食。所產的卵團具有黏絲，可附著於漂游物或底棲海藻上。
Parexocoetus mento

由wikipedia EN提供
Parexocoetus mento; also known as the African sailfin flying fish, Cuvier's flying fish, the yellow belly flying fish or the short-winged flying fish; is a species of flying fish from the family Exocoetidae which is found in the Indo-pacific region and which has colonised the eastern Mediterranean.
Description
Parexocoetus mento has an elongate body which is compressed and rounded ventrally. The lateral line has a pectoral branch. It has a protrusible upper jaw. The long pectoral fins reach the anal fin when folded but do not extend beyond it while the medium-sized pelvic fins do not extend far beyond the origin of the anal fin and are situated closer to it than they are to the pectoral fins. They are iridescent greenish-blue above and silvery below while the dorsal fin has a lot of black in it and the pectoral fins are greyish. It grows to a length of around to 10 centimetres (3.9 in).[2]
Distribution
Parexocoetus mento is found from the coast of East Africa and the Red Sea to Fiji, extending south to Queensland and the Mozambique Channel and north to southern Japan.[1] This species is recorded in the Mediterranean Sea since 1935, a likely entry via the Suez Canal.[3] It is now prevalent in the eastern Basin.[4][2]
Habitat and biology
Parexocoetus mento is found in coastal waters close to the surface and it is rarely recorded in open sea. These fishes can jump out of the water and glide over the water.[1] The eggs are covered in filaments and juveniles do not have any barbels.[2]
Taxonomy
Parexocoetus mento is the type species of the genus Parexocoetus which was erected by Pieter Bleeker in 1865,[5] this species was originally described as Exocoetus mento by Achille Valenciennes in 1847 with the type locality given as Puducherry, India.[6] Records of this species, as the subspecies atlanticus are erroneous.[1]
