Teleostei (teleosts) > Beloniformes
(Needle fishes) > Exocoetidae
Etymology: Prognichthys: Taken from Progne, name of Philomela´s sister, transformed into a swallow in the Greek mithology + Greek, ichthys = fish (Ref. 45335).
More on author: Valenciennes.
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; oceanodromous (Ref. 51243); depth range 0 - ? m. Tropical
Eastern Atlantic: Parin (1999, Ref. 47968) has shown that Prognichthys gibbifrons, previously considered to be widely distributed Atlantic species is actually restricted to waters adjacent to the western coast of tropical Africa.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 19.5 cm SL male/unsexed; (Ref. 4498)
Occurs in surface waters and capable of leaping out of the water and gliding for long distances above the surface (Ref. 3613).

Estimates based on models
Preferred temperature (Ref. 123201
): 16.2 - 25.8, mean 19.7 °C (based on 69 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00292 - 0.01429), b=3.04 (2.84 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low vulnerability (14 of 100).
