Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 27 - 29; Anal spines: 2; Anal soft rays: 8 - 10. Macrodon atricauda differs from M. ancylodon by the following characteristics: pored lateral line scales 49-63 (vs. 66-78); anal fin soft rays 9-10, rarely 8 (vs. usually 8, occasionally 9); dorsal fin soft rays 27-28, rarely 29 (vs. 28-29, rarely 27); pectoral fin rays 16-17 (vs. 15-16); largest front canines 2.5 to 3.2 in eye length, proportionally smaller and thinner when compared to M. ancylodon (Ref. 88197).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00402 - 0.00945), b=3.09 (2.97 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100).
Nutrients (Ref. 124155):  Calcium = 157 [92, 332] mg/100g; Iron = 1.26 [0.63, 2.18] mg/100g; Protein = 18.7 [17.1, 20.4] %; Omega3 = 0.24 [0.11, 0.52] g/100g; Selenium = 65.6 [33.7, 126.9] μg/100g; VitaminA = 13.2 [4.6, 39.9] μg/100g; Zinc = 1.07 [0.76, 1.55] mg/100g (wet weight);
