Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Southwest Pacific: confined to Australia, southern Queensland and New South Wales. Records from Western Australia and northern Territory need confirmation.

Biology     Glossary (e.g. epibenthic)

Usually found close inshore in tide pools (barely deep enough to keep it covered) and at the surf line, but sometimes deeper (Ref. 247). Prefers rocky shoreline areas and coral reefs (Ref. 247, 43278). Feeds on small reef invertebrates (Ref. 247), including crabs, shrimps, cuttlefish, squid and sea anemones (Ref. 43278), and small fishes (Ref. 247). Ovoviviparous (Ref. 43278, 50449). Thrives in an aquaria and capable of living out of water for a long time (Ref. 247).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.9   ±0.62 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Fec=7).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100) .
Price category (Ref. 80766):   Unknown.
