Short description Morfología | Morfometría

Vértebra: 84 - 90. This relatively small, slender species of linear-denticled Etmopterus can be separated from its closest congeners within the E. lucifer clade by a combination of characteristics: length of its anterior flank markings being much shorter than its posterior branch; black flank markings sharply demarcated by surrounding lighter to whitish lateral markings; prominent white spot on each cheek; a single white stripe extending the length of the midback; 2 parallel rows of prominent dark pores extending between pectoral and pelvic fins; its closest geographic congener E. sculptus has its anterior branch longer than its posterior branch, with a thinner posterior flank marking, 0.2-0.4% (vs. 0.6-0.9% TL in E. alphus), a higher spiral valve count 8-9 (vs. 5-7 in E. alphus); it differs from its closest morphological congener, the Australasian E. molleri by its shorter anterior (6.0-10.6% vs. 8.0-11.5% TL) and posterior (9.3-12.7% vs. 11.0-15.4% TL) flank-marking branches, biogeography and genetics (Ref. 112348).

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=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  4.1   ±0.5 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Preliminary low fecundity).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (29 of 100).
