Short description Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 14-16; Anal spines: 2; Anal soft rays: 12 - 14. Body and median fins generally brown to nearly black; body paler ventrally; fins grading to smoky gray distally. Margin of scales on sides with blackish streak, appearing as series of transverse bands; few small blue spots scattered on head and sides. Pelvic and anal fins bright blue anteriorly. Morphologically similar with S. fasciolatus but S. obreptus has well-developed serrae on the suborbital and preopercle margins, posterior outline of soft dorsal more pointed and angular, and it differs in habitat. Lips dusky brown.

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

Indo-Pacific: Ryukyu Islands, encompassing the Indo-Malayan Archipelago, Western Australia north of Abrolhos Islands; reaching eastward along the northern margin of the tropical Indian Ocean to Sri Lanka and India.

Adults occur close to shore in rocky or dead reef areas where visibility is often reduced due to silting and wave action. Territorial, they maintain and 'weed' filamentous algae patches growing on dead coral (Ref. 9710). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

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=0.02087 (-0.14952 - 0.19125), b=2.97842 (2.89203 - 3.06480), based on LWR estimates for this genus-BS (Ref. 93245).

Trophic Level (Ref. 69278): 2.0 ±0.00 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100) .

Price category (Ref. 80766): Unknown.
