Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 12 - 14; Anal spines: 3; Anal soft rays: 10 - 12. T. purpureum and T. trilobatum have nearly identical initial phases (Ref. 1602). They differ slightly in details of the head markings, and T. purpureum has a slightly longer head, shorter pectoral fins, and attains a larger size (Ref. 1602, 48636). Females best distinguished by the 'V' mark on the snout (Ref. 48636). Initial phase with a vertical dark red line below front of eye usually with a branch to front of snout (Ref 9823).

Biology     Glossary (e.g. epibenthic)

Found almost exclusively in the surge zone of outer reef flats, reef margins, and rocky coastlines, down to a depth of about 10 m (Ref. 5213). Benthopelagic (Ref. 58302). Occur in groups of females that are spread out over large reef sections and dominated by few males. Males grow much larger than females (Ref. 48636). Feed on small invertebrates (crabs, sea urchins, brittlestars, mollusks), small fishes, echinoids, ophiuroids and polychaetes (Ref. 37816). Protogynous (Ref. 55080).

Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 29.3, mean 28.3 °C (based on 3134 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00430 - 0.02123), b=3.06 (2.89 - 3.23), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.0 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
