Short description Identification keys | Morphology | Morphometrics

Ribbon - shaped body with 9 - 13 eye spots along the base of the dorsal fin (Ref. 35388).

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274); Occurs in shallow waters (seashore, tide pools), but descends (especially in winter) to 100 m or more. May remain out of water under rocks or seaweeds (Ref. 31184). Feeds on small crustaceans, polychaetes, mollusks and fish eggs. The eggs are laid on the sea bed in a large clump, which is closely guarded until hatched (Ref. 9900). Breathes air when out of water (Ref. 31184). Spawning occur in November - January . Female lays 80-200 eggs in a large ball under a stone or in an empty bivalve shell (Ref. 35388).

Estimates based on models

Preferred temperature (Ref. 115969): 4.3 - 11.9, mean 9.5 (based on 692 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00209 (0.00110 - 0.00398), b=3.17 (3.00 - 3.34), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.46 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=1-3; K=0.18-0.29; tmax=12).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100).
