Short description
Khóa để định loại | Hình thái học | Sinh trắc học
Động vật có xương sống: 37 - 38. This species is distinguished from its congeners by the following set of characters: dorsal head profile straight between nape above eye and upper lip tip; the posterior angle of jaws extends to between a vertical line drawn through the posterior edge of the anterior nostril and a vertical line drawn through the anterior edge of the eye; infraorbital invagination vertical to posterior part of the eye; posterior opercular edge w-shaped with 2 equally long tips; longitudinal infralateral and suborbital transversal rows of superficial neuromasts are placed in the well-defined deep groove; trunk cross-section behind pectoral fin base half oval with straight ventral side; body granules shallow and inconspicuous; vertical eye diameter 2.6-3.3% of SL; horizontal eye diameter 2.3–2.9% of SL; head length 24.3-28.8% of SL; pectoral-fin length 8.6-9.3% of SL; prepectoral distance 24.4-28.4% of SL; ventral adhesive disc length 17.1-19.3% of SL; caudal-fin length 13.5-15.5% of SL; moderate number of vertebrae for the genus 37-38; pharyngeal jaws with small ceratobranchial 5, having several small conical teeth; nasal bones club-shaped; star-like pigmentation around eyes, body colouration when alive dark with clear stripes visible in less pigmented specimens (Ref. 123696).
Inhabits shallow waters (Ref. 10954). It reaches highest abundances in pebble and boulder beaches of less than 0.5 m depth (24 individuals/m2 in Messina), but reported to be found down to 2 m of water depth. It was also observed to occur with Lepadogaster lepadogaster and that males build and guard nests under boulders during spawning season (Ref. 123696),
