Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); chledophilum: Name from the Greek, ‘chledos’ for mud and ‘phileo’ for loving; referring to its predilection for mud bottom habitats, which is unusual for members of this genus, which are more commonly found on coral reefs..

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9 - 10; Anal spines: 1; Anal soft rays: 8 - 9. This species is distinguished by the following set of characters: D VI + I,9 (rarely 10), with the second spine elongated and filamentous, reaching caudal-fin base when fully developed; A I,8 (rarely 9);the fifth pelvic ray is branched, 62-71% length of fourth pelvic ray; the bony interorbital 46-62% pupil diameter; the midline of predorsal broadly scaleless; no scales on cheek and opercle; in life mainly bright orange-red except white on breast and belly, the lower half of head, also white stripe on midline of snout in life (Ref. 100512).

Found in an area consisted of pieces of metal wreckage and discarded tyres on mud bottom; it either rested on the bottom or hovered in midwater in the shady recesses of the wreckage or tyres (Ref. 100512).

Estimates based on models

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

Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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).
