Short description Identification keys | Morphology | Morphometrics

Body elongate, laterally compressed. Greatest body depth at origin of first dorsal fin. Scales absent, except for lateral-line scales, embedded in skin. Kali falx is diagnosed from its congeners by a unique characteristic: first tooth in lateral remarkably enlarged, 17.2-20.5% in premaxillary length, sickle-shaped, projecting anteriorly (vs. first tooth in lateral series of premaxilla of same size or smaller than adjacent teeth in K. colubrina, K. kerberti, K. macrodon, K. macrura, and K. parri; fang-like, 15.2-16.4% in premaxillary length, slightly curved, not projecting anteriorly in K. indica).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.2 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
