Actinopteri (ray-finned fishes) > 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).
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; oceanodromous; depth range - m (Ref. ), usually - m (Ref. ). Tropical; 0°C - ; 28°N - 1°S
Eastern Central Pacific: Gulf of California to Ecuador.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 16.0 cm SL male/unsexed; (Ref. 9300)
Epipelagic and neritic in coastal waters (Ref. 36606). May leap out of the water and glide for considerable distances from the surface. Oviparous, with planktonic larvae (Ref. 36606). Eggs are presumably attached to one another or floating objects via filaments (Ref. 36606).

Estimates based on models
Preferred temperature (Ref. 115969
): 15.9 - 26.1, mean 21.4 °C (based on 34 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00162 - 0.01126), b=3.12 (2.89 - 3.35), 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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
