A few scattered small dark-edged pale spots on postorbital head and body above pectoral fins. No white margin posteriorly on caudal fin.

特殊的有肉峰的背面; 触角只在雄性成鱼中。 在胸鳍上面的在眼眶后的头部与身体上的一些分散的小黑色边的灰白斑点。 没有白色的边缘在尾鳍后面。 吻从口部到眼的轮廓强烈倾斜, 形成对身体 (参考文献 9808) 的水平轴的一个大约 40个 ° 的角.
Inhabits deep coastal, usually in small groups but occasionally in large schools (Ref. 48637). Sometimes solitary (Ref. 90102). An uncommon species found in seaward reef slopes (Ref. 9710, 48637), also along rocky shores (Ref. 30573). Feeds on benthic algae (Ref. 30573). Caught with nets (Ref. 30573).
深地栖息于海岸的, 通常群集成小群鱼群但是偶见于大群鱼群.(参考文献 48637) 发现于临海礁石斜坡 (参考文献 9710,48637) 的一个稀有的种, 也沿着岩岸。 (参考文献 30573) 吃底部的藻类。 (参考文献 30573) 用网捕获了。 (参考文献 30573)
