Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 26.0 cm TL male/unsexed; (Ref. 5640)
Adults in aggregation roam over sandy bottoms. Probably carnivorous, feed on mollusks and diatoms (Ref. 6770). Females brood their young in the mouth (Ref. 86760).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00696 - 0.03143), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.7 ±0.32 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
