Actinopterygii (ray-finned fishes) > Perciformes (Perch-likes) > Pomacentridae (Damselfishes) > Pomacentrinae
Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335);  earina: Name from Latinized form of the Greek adjective 'earinos' meaning 'the color of spring', which is green; referring to the pale green color of this species in life.

Environment / Climate / Range Ecology

Marine; reef-associated; depth range 60 - 116 m (Ref. 59379).   Tropical, preferred ?; 9°N - 21°S, 129°E - 178°W

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

Western Pacific: from Puluwat westward to Palau; south to Papua New Guinea, Vanuatu and Fiji; also Indonesia. It was not observed at Rarotonga (Cook Islands), Kiritimati (Line Islands), nor American Samoa during brief surveys of deep reefs at these localities.

Short description Morphology | Morphometrics

Dorsal spines (total): 12 - 13; Dorsal soft rays (total): 11-12; Anal spines: 2; Anal soft rays: 12. This species is distinguished by the following characters: Dorsal rays XII-XIII, 11-12, usually XIII, 12; anal rays II, 12; pectoral rays 17-18, usually 18; spiniform caudal rays 3; tubed lateral-line scales 13-15, rarely 16; gill rakers 6-8 + 18-21 (total 26-28, rarely 25); body depth 1.65-1.9 in SL. The color when fresh is pale slate blue (bright pale green in life) with a white spot (sometimes two white spots) roughly the size of a scale mid-laterally on the body; malachite green area above orbit and in inter-orbital space and nape; the dorsal and anal fins with bright distal border of pale turquoise blue (Ref. 59379).

Biology     Glossary (e.g. epibenthic)

Adults inhabit steep outer reef slopes and drop-offs with rocky outcrops and small caves and holes, often in association with limestone talus; usually observed in pairs or small groups, feeding low in the water column, and are generally abundant where they are found (Ref. 59379). 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 models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.00811 - 0.04082), b=3.00 (2.83 - 3.17), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.1 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (16 of 100) .
