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

Southeast Atlantic: endemic to South Africa. There are old records from Madagascar and Mauritius, but these require confirmation (Ref. 244).

Occurs in the continental shelf, both inshore and offshore (Ref. 5578). Prefers rocky reefs from the intertidal zone down to 100 m depth (Ref. 5578). Nocturnal, often found in caves and crevices during the day (Ref. 5578). Feeds mainly on crustaceans, but also bony fish and cephalopods (Ref. 244). Oviparous (Ref. 50449). Readily kept in captivity (Ref. 244).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00337 (-0.12989 - 0.13664), b=3.15644 (3.06916 - 3.24372), based on LWR estimates for species & family-BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.6 ±0.5 se; Based on diet studies.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100) .

Price category (Ref. 80766): Low.
