Morphology | Morphometrics
This species is distinguished from its congeners by the following characters: slender head and snout, only slightly bell-shaped in dorsoventral view without distinct lateral indention (vs. distinctly bell-shaped snouts with a strong lateral indention anterior to outer nostrils); has broader claspers in adult males, the base width 2.1% TL (vs. 1.51.8% TL of congeners in the western Indian Ocean); further differs from B. clevai by having a smaller maximum size and a color pattern of fewer and smaller blotches, larger oral papillae, a shorter snout, and broader claspers without knob-like apex and with a smaller envelope and a subtriangular (vs. subrectangular) exorhipidion; differs from B. hispidus by having a longer snout, a longer dorsal-caudal space, broader clasper without knob-like apex, and fewer vertebral centra; differs from B. lutarius by having a smaller maximum size and has a blotched (vs. largely plain) coloration, numerous (vs. lacking) oral papillae, shorter anterior nasal flaps, a longer caudal fin, a shorter pelvic anal space, and shorter and broader claspers (Ref. 104913).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 5.0 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Very high vulnerability (85 of 100) .
