Biology     Glossary (e.g. epibenthic)

Adults are found over sandy bottoms often in pairs. Form schools. Feed on copepods and small shrimps (Ref. 6770). Exhibit biparental mouthbrooding of the young (Ref. 86760).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

After the male has fertilized the eggs the female mouthbroods them for 12 days after which they are transferred to the male for an additional 18-20 days of mouthbrooding (Ref. 2060). In one study, larvae of up to 0.99 cm TL are mouthbrooded by female parents 6.8 to 7.5 cm SL in size (Ref. 86760).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00700 - 0.03275), 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):  3.3   ±0.38 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Fec=20).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Price category (Ref. 80766):   Unknown.
