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.
More on author: Lowe.

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.
東大西洋與地中海: 肯定地已知只來自馬得拉群島，西西里島 (義大利) ，直布羅陀海峽了, 與毗連的大西洋外海的葡萄牙南部。 能被預期出現廣泛地在東方與也許中央的北大西洋中排列。 東大西洋中部來自日本延繩釣的資料需要澄清的紀錄。 高度遷移的種,1982年海事法會議的附件一.(參考文獻 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).
更高深的研究强烈地被需要以澄清这种的有效性。 可能大洋性。 长度已经在从 ' 体长' 到 FL 被转移。 (*0.15)

Estimates based on models
Preferred temperature (Ref. 115969): 14.3 - 19.1, mean 17.1 (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).
营养阶层 (Ref. 69278): 4.3 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref. 120179): 高度, 族群倍增时间少于 15个月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
