Etymology: Scolopsis: Greek, skolex = worm + Greek, opsis = appearance (Ref. 45335).
More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 20 - 50 m (Ref. 28016). Tropical; 31°N - 5°N, 31°E - 82°E (Ref. 3810)
Western Indian Ocean: Red Sea, Gulf of Aden, Gulf of Oman, Persian Gulf, Arabian Sea and Sri Lanka (Gulf of Mannar). This species has been misidentified as Scolopsides rupellii (=Scolopsis vosmeri) or as Scolopsis phaeops (= Scolopsis frenatus) by some authors.

Estimates based on models
Preferred temperature (Ref. 115969
): 24.4 - 29.2, mean 26.4 °C (based on 59 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01698 (0.00761 - 0.03792), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.5 se; based on size and trophs of closest relatives
Generation time: 1.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (tm=1.1; Tmax=5; K=1.17).
