Actinopteri (ray-finned fishes) > Eupercaria/misc
(Various families in series Eupercaria) > Malacanthidae
Etymology: Hoplolatilus: Greek, hoplon = weapon + Latin, latus = wide (Ref. 45335).
More on author: Günther.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 40 - 70 m (Ref. 37816). Tropical; 24°N - 21°S
Indo-West Pacific: off Kosi Bay in South Africa (Ref. 11228) eastward to the Solomon Islands, north to the Philippines, Palau, and the Marshall Islands (Ref. 33390).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 21.0 cm TL male/unsexed; (Ref. 5591); common length : 16.9 cm SL male/unsexed; (Ref. 37816)
soft rays: 12;
Vertebrae: 24. Body pale olive-grey, darker above, belly pale blue; bluish violet band joining eyes across front of snout; lips and cheeks blue; upper 1/3 of pectoral fins bluish white, remainder pale yellow (Ref. 5591). This rare species has the deepest body in the genus and a thicker tail than H. cuniculus and H. starcki (Ref. 37816).
Inhabits sandy areas at bases of reefs (Ref. 9710). A rare species that schools above huge mounds of rubble that it apparently builds (up to 5.5 m long x 3 m wide over 1 m high). Solitary or in pairs (Ref 90102).
Life cycle and mating behavior

Displays obligate monogamy where a one-to-one pair is established irrespective of resource abundance (Ref. 52884).
