背棘 (總數) : 7; 背的軟條 (總數) : 13 - 14; 臀棘: 1; 臀鰭軟條: 12 - 13. This species is distinguished from its congeners by the following characters: scales in lateral series 51-59; predorsal scales 25-35; in adults, opercle with 10-16 scales; pectoral-fin rays 18-20; free tips on upper pectoral rays well developed and the first ray longer than two thirds of the entire ray length; pelvic fin disc is complete, its anterior membrane without lateral lobes; anterior oculoscapular canal with pore 'alpha' at rear of orbit; oculoscapular row x1 is not extending forwards to pore ß; suborbital row d is discontinuous with large gap below suborbital rows 3 and 4; eye diameter 1.08-1.32 in snout length; the pigment dots on the cheek are irregularly scattered or, if rows are visible, then additional dots or a third row are present across the middle of the cheek between the lower row starting anteriorly at the angle of mouth and the upper row that touches ventral margin of eye; upper mark on the P base single or doubled, reaching downwards to 8th-10th rays counting from the upper part of fin (Ref. 110727).
G. incognitus differs from G. bucchichi by the following morphological characters: dots on the cheek irregularly scattered or, if rows are visible, then additional dots or a third row present across the middle of the cheek between the lower row starting anteriorly at the angle of mouth and the upper row that touches ventral margin of eye vs. 2 rows two rows of elongated dots on cheek without dots between them at the middle of the cheek, the lower row starting anteriorly at the angle of mouth and going posteriorly across cheek and opercle to pectoral-fin base, and the upper row starting at upper lips, going posterodorsally to touch ventral margin of eye and continuing behind eye; upper mark on the P base single or doubled, reaching downwards to 8th-10th rays counting from the upper end vs. upper mark on the P base single or doubled, reaching downwards to 6th to 7th rays counting from upper end; pectoral-fin rays 18-20 (rarely 18) vs. 17-18; free tips on upper pectoral rays well developed and the first ray longer than two thirds of the entire ray length vs. free tips on three upper pectoral rays moderately developed and the first ray shorter than half of the entire ray length; in adults, opercle with 10-16 scales vs. naked, rarely 2-4 scales may be visible; predorsal scales 25-35 (rarely 25) vs. 20-25 (rarely 25); suborbital row d is discontinuous with large gap below suborbital rows 3 and 4 vs. suborbital row d continuous; eye diameter 1.08-1.32 in snout length vs. eyes larger and snout shorter with eye diameter 0?82–1?04 in snout length) (Ref. 110727).
Body shape (shape guide): elongated; Cross section: compressed.
Collected from just below the water surface (north Adriatic Sea) down to 12 m in depth (Israel). The depth range in Israel (4-12 m) was deeper compared with other areas (Adriatic 0-5 m, France 1.5-6 m, Crete 2-9 m). It occurs on all kinds of substrata: sand, gravel, cobbles, boulders and bedrock, but mostly on different combinations of mixed substratum which can be bare or
covered to varying degrees by short thallus algae, Caulerpa prolifera and Cystoseira
spp., or sea grasses Posidonia oceanica and Cymodocea nodosa (Ref. 110727).
