Actinopteri (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). More on author: Lesueur.
Issue on validity of subspecies: subspecies considered as valid in FB, elevated to species rank as Platybelone argalus (Lesueur, 1821) 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; reef-associated; depth range 0 - ? m, usually 0 - 2 m (Ref. 40849). Subtropical; 37°N - 29°S, 98°W - 34°W
Western Atlantic: North Carolina, USA to Brazil (Ref. 7251), including the Bahamas, Gulf of Mexico, and Caribbean Sea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 50.0 cm TL male/unsexed; (Ref. 26340); common length : 35.0 cm TL male/unsexed; (Ref. 5217)
soft rays: 17 - 20. Gill rakers present; caudal peduncle with a lateral keel, the lateral line passing ventral to it.
Occurs offshore; particularly abundant around islands (Ref. 5217); schools in sheltered parts of the reef (Ref. 48635). Feeds mainly on small fishes. Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205).
