特殊的有肉峰的背面; 觸角只在雄性成魚中。 在胸鰭上面的在眼眶後的頭部與身體上的一些分散的小黑色邊的灰白斑點。 沒有白色的邊緣在尾鰭後面。 吻從口部到眼的輪廓強烈傾斜, 形成對身體 (參考文獻 9808) 的水平軸的一個大約 40個 ° 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).
