Etymology: Axoclinus: Greek, axis = axis + Greek, klinein = sloping and bed, due to the four apophyses of sphenoid bone.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 7 - 8 m (Ref. 46206). Tropical
Eastern Central Pacific: Isla del Coco. A very similar but possibly undescribed species from the Revillagigedo Islands.

Max length : 3.5 cm TL male/unsexed; (Ref. 11482)
Morphology | Morphometrics
soft rays: 18. Lateral line gradually descending from upper edge of gill cover to midlateral axis; lateral line with 21-26 tubed scales followed by 8-12 notched scales; total scales in longitudinal series 33-35; a small lanceolate cirrus on upper edge of eye. Head pink to reddish; side with 3 broad, dark brown bars with narrow, whitish spaces between them; a black band around base of caudal fin; caudal fin frequently black (Ref. 11482).
Adults inhabit shallow rocky areas. They feed on tiny invertebrates and algae (Ref. 11482). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
