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

Western Indian Ocean: off Madagascar and from southern Mozambique to Cape Agulhas, South Africa.

Found on the continental shelf and upper slope to at least 430 m (Ref. 247). Feeds on bony fish, also shrimp, mysids and squid (Ref. 5578). Ovoviviparous (Ref. 50449), with 5 to 7 young in a litter (Ref. 247). Probably uses its saw to stun and kill prey (Ref. 5578). Sometimes caught by sports anglers (Ref. 5578).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 1.0156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (-0.16711 - 0.17489), b=3.12000 (3.03000 - 3.21000), based on all LWR estimates for this BS (Ref. 93245).

Trophic Level (Ref. 69278): 4.2 ±0.7 se; Based on diet studies.

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (Fec=5).

Vulnerability (Ref. 59153): High to very high vulnerability (75 of 100) .

Price category (Ref. 80766): Unknown.
