Краткое описание
морфология | морфометрия
членистые (мягкие) лучи спинного плавника (общее число): 21-23; членистые (мягкие) лучи анального плавника: 4. Body orange yellow when fresh. Trunk rings 20, tail rings 15. Lateral trunk ridge continuous with inferior tail ridge; superior trunk and tail ridges extending forward over 4 trunk rings. Three serrated ridges dorsally on snout, the median ridge heavily serrated. Body ridges illustrating single spine except anterior six of superior trunk ridge and 3 lateral trunk ridge which has double spines. No ventrolateral projection on the snout.
Inhabits small caves in sublittoral rocky reefs. Reported from tide pools to depths of at least 25 m offshore, but mostly seen in shallow depths (Ref. 48635). An active cleaner that shares crevices with shrimps, large mud crabs and sometimes moray eels (Ref. 48635). Solitary or in pairs near sponges and Diadema sea urchins (Ref 90102). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Spawns from the end of May to September.
Life cycle and mating behavior

Monogamous mating is observed as both obligate and genetic (Ref. 52884). Male carries the eggs in a brood pouch (Ref. 205).
