Maturity: Lm ? range ? - ? cm

背棘 (总数) : 17; 背的软条 (总数) : 10 - 11; 臀棘: 3; 臀鳍软条: 9 - 11. Small to medium-sized with the plesiomorphic melanin pattern. Differs from the other species with this pattern in the higher number of gill-rakers (16-18) and in the greater emphasis of the blotches along the dorsum in the overall pattern. Differs further from P. marginatus in the more posterior position of the deepest part of the body.
小型到中型的有形状类似的黑色素图案。 有别于在较多的鳃耙 (16-18) 与斑块的较大的强调中有这一个图案的另一个种在整体的图案中沿着背面。 在身体的最深部份的较向后位置中进一步不同于 P. marginatus 。
Favors a sediment-free rocky habitat, where it stays in midwater about one meter away from the substrate. Is normally found just below the surface, rarely deeper than 5 m. Mostly seen at places where the rocky coast drops steeply. Feeds on invertebrates taken from the water and on insects that fall into the water (Ref. 5595).
喜欢一个无沉淀物岩石的栖息地, 在哪里它停留在中层水域中大约一公尺左右远离底部。 通常被发现紧邻水面下, 非深度超过 5 公尺。 大部份在岩石的海岸险峻地降低的地方见到。 抓离水面与在掉入水中的昆虫身上吃无脊椎动物。 (参考文献 5595)
