Short description Chiavi di identificazione | Morfologia | Morfometria

Vertebre: 80 - 86. This relatively small, slender, species of linear-denticled Etmopterus can be distinguished from its closest congeners within the E. lucifer clade by the following set of characters: length of its anterior flank markings slightly shorter than its posterior branch; long caudal base marking; irregular and variable number of black, horizontal, dash-like marks on sides of body; differs from E. brachyurus in having a shorter posterior caudal marking (2.8-4.4 vs. 4.2-6.1% TL), longer caudal base marking (10.6-14.1 vs. 7.0-7.8% TL), and flank marking with a slightly shorter posterior branch (9.1-11.2 vs. 11.4-12.6% TL) (Ref. 116206).

The female individual (27.7 cm TL) was found to be pregnant and the 2 males (23 cm and 26.5 cm TL) were determined to be mature (Ref. 116206).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00191 - 0.00758), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.5 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary low fecundity).

Fishing Vulnerability (Ref. 59153): Low vulnerability (18 of 100).
