Etymology: Tetrapturus: Greek, tetra = four + Greek, pteron, fin, wing (Ref. 45335).
Eponymy: Albert Pflueger Sr. (d: 1962) was a taxidermist based in Miami who invented a new method of mounting fish specimens, especially large ‘sport’ specimens like tarpon and sailfish. (Ref. 128868), visit book page.

Ambiente: milieu / zona climatica / distribuzione batimetrica / gamma di distribuzione
Ecologia
marino pelagic-oceanic; oceanodromo (Ref. 71039); distribuzione batimetrica 0 - 200 m (Ref. 43), usually 100 - ? m (Ref. 4770). Subtropical; 44°N - 33°S, 98°W - 17°E (Ref. 43)
Atlantic Ocean: widely distributed in offshore waters, much more densely so in the western than in the eastern Atlantic. Highly migratory species.

Max length : 254 cm FL maschio/sesso non determinato; (Ref. 40637); common length : 165 cm OT maschio/sesso non determinato; (Ref. 43); peso massimo pubblicato: 58.0 kg (Ref. 40637)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 50 - 57; Spine anali: 0; Raggi anali molli: 18 - 21; Vertebre: 24. Blue-black above, silvery white splattered with brown on the sides, silvery white below; dorsal fins dark blue; pectorals blackish brown, occasionally with tinges of greyish white; pelvic fins blue-black with a black fin membrane; 1st anal fin dark blue with silvery white at base; 2nd anal fin blackish brown.
Body shape (shape guide): elongated.
Oceanic species, chiefly found in offshore waters, usually above the thermocline. Feed mainly on pelagic fishes and squids (Ref. 4770). Females probably spawn once a year (Ref. 4770). Marketed frozen.
Ciclo vitale e comportamento di accoppiamento
Maturità | Riproduzione | Deposizione | Uova | Fecondità | Larve
Maturation seems to occur at the same time rather than in the same season both in the northern and southern hemisphere, which could be suggestive of homogeneity of the population of this species. Females probably spawn once a year (Ref. 4770).
