Morphology | Morphometrics
A very small, black shark with a short and bluntly rounded snout (its length 5.7-7.5% TL in adults); head and body nearly cylindrical anteriorly, tapering unevenly to a slender caudal peduncle; moderately large eyes; dermal denticles, very small needle-like to spine-like, covering whole body except narrowly along lips, gill slit margins, around cloacal opening, and dorsal surface of claspers. Pectoral fins lobate; small pelvic fins.
Ovoviviparous (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00178 - 0.00811), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153
): Low vulnerability (11 of 100) .
