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

Eastern Indian Ocean: Endemic to southern regions of the Australian continental shelf. Distribution ranges from Kangaroo Island in South Australia (Ref. 27573) to Geraldton in Western Australia (Ref. 6335). Report from Western Victoria (Ref. 6205) is erroneous (Ref. 6390). Not yet recorded from western Tasmania.

Biology     Glossary (e.g. epibenthic)

Live close to the sea bed over sandy substrates. Occur in the surf zone of beaches and quiet waters of bays and sandbanks. Are trawled in offshore waters to at least 55 m and possibly deeper. Juveniles may be found in shallow water off white sand beaches, together with accumulations of dead seaweed in the surf zone during spring and summer in Western Australia. Move into shallow waters in large schools during full moon (Ref. 6205). Feed mainly on crustaceans, amphipods, decapods, mysids and copepods. Juveniles consume mostly copepods (Ref. 6223). Oviparous (Ref. 205), and are multiple spawners with asynchronous development (Ref. 12343).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00350 - 0.02070), b=3.09 (2.88 - 3.30), based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.47 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.26-0.29).
Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100) .
Price category (Ref. 80766):   Very high.
