Etymology: Thalassoma: Greek, thalassa = the sea + Greek, soma = body; the colour of the sea (Ref. 45335).
More on authors: Quoy & Gaimard.

Issue
Related species: Thalassoma sanctahelenae (St. Helena I,), and Thalassoma newtoni (West Central Atlantic) (Ref. 50607).

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; reef-associated; depth range 0 - 50 m (Ref. 86997). Tropical; 8°S - 10°S, 15°W - 14°W

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

Central Atlantic: Ascension I. (Ref. 98447).

Reports from other areas are doubtful: St. Helena (in Ref. 5292; see Ref. 119515); São Tomé Island: intermediate form with Thalassoma pavo (Ref. 34088). Ghana and other localities on the west African coasts (Ref. 86997). If reports would be confirmed, they are more likely the result of human transportation (Ref. 98447).

Estimates based on models

Preferred temperature (Ref. 123201): 23 - 27.7, mean 26.4 °C (based on 9 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00180 - 0.01107), b=3.11 (2.89 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
