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 ). Mature gonads are symmetrical in terms of mass, and similar in ovarian follicle number and size (Ref. 58429 ). Egg laying possibly throughout the year (Ref. 58429 ).

Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 4.1 - 7.8, mean 5.7 (based on 44 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00490 (0.00244 - 0.00981), b=3.13 (2.96 - 3.30), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.8   ±0.52 se; Based on food items. Resilience (Ref. 69278 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100). Vulnerability (Ref. 59153 ):  Low vulnerability (22 of 100) .
