توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 2; شعاع نرم باله پشتي (کل) : 7 - 8; شعاع نرم باله مخرجي: 5 - 6. This species is distinguished by the following set of characters: ventral surface of trunk with small to relatively large coalescent platelets, forming a typical mosaic-like pattern; small, whitish yellow or beige blotches at least on the predorsal portion of body; flanks covered by small dark brown or black blotches, which can be roughly longitudinally aligned and variably fused with each other, forming narrow, disrupted irregular lines, but not solid stripes; typically having more numerous pale blotches on the body; large, smoothly arched dark brown or black patch present, extending from anterior portion of parieto-supraoccipital towards region of interopercle, transversally crossing the orbit and forming the typical mask-like blotch; mosaic-like pattern of plates entirely or almost entirely covering the ventral surface of trunk (Ref. 137472).
Body shape (shape guide): short and / or deep; Cross section: oval.
