Etymology: Thalassoma: Greek, thalassa = the sea + Greek, soma = body; the colour of the sea (Ref. 45335); robertsoni: Named in honor of Dr. D. Ross Robertson of the Smithsonian Tropical Research Institute for his contributions to the knowledge of reef fishes of both the eastern Pacific and Caribbean regions.
Eponymy: Dr David Ross Robertson (d: 1946) is an ichthyologist whose bachelor’s degree (1966) and doctorate (1974) were awarded by The University of Queensland, Australia. [...] (Ref. 128868), visit book page.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00430 - 0.02222), b=3.05 (2.88 - 3.22), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±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).
