Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Istiophoridae
Etymology: Tetrapturus: Greek, tetra = four + Greek, pteron, fin, wing (Ref. 45335). More on author: Lowe.
Environment / Climate / Range
Marine; pelagic-oceanic; oceanodromous (Ref. 51243); depth range 0 - 200 m (Ref. 43). Subtropical; 45°N - 20°N, 31°W - 11°E (Ref. 43)
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 184 cm FL male/unsexed; (Ref. 43); 181.0 cm FL (female); max. published weight: 21.5 kg (Ref. 43); max. published weight: 21.5 kg
Eastern Atlantic and Mediterranean Sea: Positively known only from Madeira, Sicily (Italy), Strait of Gibraltar, and the adjacent Atlantic Ocean off southern Portugal. Can be expected to range widely in the eastern and perhaps central North Atlantic. Central and eastern Atlantic records from Japanese longliner's data need clarification. Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea (Ref. 26139).
Further study is strongly needed to clarify the validity of this species. Probably oceanic. Length has been transferred from 'Body length' to FL (* 0.15).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5630 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00197 - 0.01011), b=3.14 (2.94 - 3.34), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.5 ±0.8 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (47 of 100) .
