Etymology: Tetrapturus: Greek, tetra = four + Greek, pteron, fin, wing (Ref. 45335).
Eponymy: George Butler Leacock supplied Lowe with the spearfish holotype and “…rendered valuable assistance to the cause of ichthyology of this island [Madeira]… …generally as well as in this instance. [...] (Ref. 128868), visit book page.

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.

Size / Vikt / Age

Maturity: L_m ? range ? - ? cm
Max length : 184 cm FL hane/ej könsbestämd; (Ref. 43); 181.0 cm FL (female); publicerad maxvikt: 21.5 kg (Ref. 43); publicerad maxvikt: 21.5 kg

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 based on models

Preferred temperature (Ref. 123201): 14.3 - 19.1, mean 17.1 °C (based on 37 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5630 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00195 - 0.01025), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.3 ±0.4 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
