Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335).
Eponymy: Dr William Beverly ‘Bev’ Scott (1917–2014) was Curator of Ichthyology and Herpetology, Royal Ontario Museum (Toronto, Canada) (1950–1974) and then Scientist Emeritus. [...] (Ref. 128868), visit book page.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; non-migratory; depth range 15 - 116 m (Ref. 13442), usually 15 - 30 m (Ref. 9710). Tropical; 35°N - 23°S, 100°W - 34°W
Western Atlantic: southern Florida, USA and the Caribbean Sea (Ref. 7247) to northern Brazil (Ref. 57756). More abundant at continental locations (Ref. 51183).
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 10.0 cm TL male/unsexed; (Ref. 9710)
Dorsal spines (total): 13; Dorsal soft rays (total): 11 - 12; Anal spines: 2; Anal soft rays: 11 - 12. Adults gray brown dorsally, often shading white ventrally, with purple- blue markings, many as vertical lines; upper edge of eye bright purple-blue; juveniles blue (Ref. 13442).
Adults occur in steep outer slopes and deeper patch reefs (Ref. 7247). 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 based on models
Preferred temperature (Ref.
123201): 23.9 - 28, mean 26.8 °C (based on 126 cells).
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.00804 - 0.04119), b=2.99 (2.81 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±0.45 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
