Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 2850)

Found in eelgrass beds and in drifting algae, and off rocky shores (Ref. 2850). Some specimens have been captured by dipnet under a light at night (Ref. 2850). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Minimum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 123201): 16 - 26.6, mean 19 °C (based on 64 cells).

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

Bayesian length-weight: a=0.00028 (0.00012 - 0.00064), b=3.21 (3.03 - 3.39), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).
