Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0. Gill opening reduced to a pore located in the membrane above the opercle. Gill membranes fused to the body and isthmus. Superior trunk and tail ridges continuous, inferior trunk and tail ridges discontinuous, lateral trunk ridge confluent with inferior tail ridge. Brood area of male located under trunk. Rings: 28-31+60-69; Dorsal 37-47; Sub-dorsal 11-7+2-4; Caudal 4-9, rudimentary.

Biology     Glossary (e.g. epibenthic)

Adults inhabit inshore waters, among algae. Females with 1,000 or more ovarian eggs (Ref. 6733). Feed on small crustaceans and fish fry (Ref. 35388). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 7.3 - 12.5, mean 10.1 °C (based on 1036 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00062 (0.00026 - 0.00147), b=2.99 (2.78 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.44 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=2).
