Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); benjamini: Named for Peter Benjamin, Toronto entrepreneur, Benjamin Films Ltd (Ref. 100726).
Eponymy: Peter Benjamin owns Benjamin Film Laboratory (Toronto), and is a keen amateur ichthyologist. He provided Winterbottom with free 35mm film and processing over two decades and has participated in several collecting expeditions. (Ref. 128868), visit book page.

背棘 (總數) : 7; 背的軟條 (總數) : 9 - 10; 臀棘: 1; 臀鰭軟條: 8 - 10. Distinguished by having the following characters: a deep concave, ‘U’-shaped interorbital trench; the bony interorbital about half pupil-diameter in width; with a slight groove posterodorsal to the eye; without median predorsal scales, sides of nape covered with small scales reaching to or near to the eyes; cheek and operculum without scales; base of pectoral-fin with oval, moderate-sized scales; prepelvic area with 5-6 rows of cycloid scales, isthmus naked anteriorly, with one slightly enlarged scale on the membrane between the bases of the pelvic fins; central 6-13 pectoral rays branched, uppermost and lowermost rays unbranched; fifth pelvic-fin ray branched once dichotomously and about 60-75% length of the fourth; all other rays usually with one sequential branch, basal membrane connecting the two pelvic fins only at the base; second dorsal spine longest, usually filamentous, extending at most to midway along the base of the second dorsal fin in Australian material; D2 usually I,10; A usually I, 9; nape crest fleshy from the first dorsal origin to above the operculum; when alive, head and body red, preserved yellow, the head with a thin vertical grey (bluish grey in life) bar from the anteroventral margin of the eye to the middle of the jaws and a second bar extending more-or-less vertically downward onto cheek from about the middle of the eye (often persisting in preserved material as faint grey bars); orbit rimmed with a thin band of melanophores, more distinct dorsally but faded in preserved material (Ref. 100726).
Cross section: oval.
Specimens were collected with rotenone (Ref. 13702). Inhabits coastal and outer reef slopes (Ref. 37816, 48637). Benthic, occuring singly or in loose groups, and a plankton-feeder; with prolonged pelagic larval duration of 33.9 days (= 24% of maximum lifespan) and linear post-larval growth; daily mortality rate ranging from 2.9% to 6.3%; sex ratio of 1:1.6 male/females) (Ref. 87294).
