Type specimen taken from a depth of about 24 m (Ref. 26282). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Feeds on fishes, crustaceans and cephalopods (Ref. 57911).
Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00562 (0.00287 - 0.01102), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245). |
|
Trophic level (Ref. 69278) |
4.2 ±0.58 se; based on food items. |
|
Resilience (Ref. 120179) |
Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100). |
