Etymology: Thalassoma: Greek, thalassa = the sea + Greek, soma = body; the colour of the sea (Ref. 45335). More on authors: Quoy & Gaimard.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 50 m (Ref. 86997). Tropical; 8°S - 10°S, 15°W - 14°W
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).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 10.0 cm SL male/unsexed; (Ref. 5292)
Max depth: at least 50m (Ref. 86997). Littoral, near rocks and seagrass (Ref. 5292). Juveniles have been observed cleaning many other fish species (Ref. 98447).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Protogynous hermaphrodite, with distinct sexual dichromatism (Ref. 5292). Derived from family: Oviparous, distinct pairing during breeding (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 115969
): 23 - 27.7, mean 26.4 °C (based on 9 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00203 - 0.01181), b=3.11 (2.90 - 3.32), 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.).
Vulnerability (Ref. 59153
): Low vulnerability (22 of 100) .
