Actinopterygii (ray-finned fishes) > Beloniformes
(Needle fishes) > Belonidae
Etymology: Platybelone: Greek, platys = flat + Greek, belone = needle; any fish with sharp pointed snout; also Pierre Belon, 1517-64, French zoologist born in Le Mans. Professor at the College de France, author of " La nature et diversité des poissons", 1551 (Ref. 45335).
Issue on validity of subspecies: subspecies considered as valid in FB, elevated to species rank as Platybelone annobonensis Collette & Parin, 1970 in Eschmeyer (CofF ver. Mar. 2011: Ref. 86697). Please send references, or more studies are needed.
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-neritic; depth range 0 - ? m. Tropical
Eastern Atlantic: restricted to Annobon, Fernando Poo and São Tomé in equatorial Gulf of Guinea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 23.0 cm OT male/unsexed; (Ref. 5757); common length : 80.0 cm SL male/unsexed; (Ref. 2683)
Maximum length refers to body length. Inhabits surface waters (Ref. 2683). Circumglobal in tropical seas and divisible into five subspecies (Ref 90102).

Phylogenetic diversity index (Ref. 82805
= No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00129 (0.00058 - 0.00284), b=3.10 (2.92 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
