Short description Identification keys | Morphology | Morphometrics

Body strongly marked with light and dark areas, streaks and spots; very small (probably the smallest shark) with a somewhat flattened head and snout (its depth 2/3 or less than its width); moderately large eyes; slender, needle-shaped denticles in random, dense array; fins moderately large.

Ovoviviparous (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 9.6 - 13.8, mean 11.9 °C (based on 10 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00194 - 0.00745), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.5 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).

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