Etymology: Schismatogobius: Greek, schisma, -atos = crack, fissure + latin, gobius = gudgeon (Ref. 45335); saurii: Named for its very cryptic appearance against the gravel substrates of their habitats, the stealthy capacity of this species reminds us of Japanese ‘‘ninja,’’ which were known as masters of camouflage; noun in apposition..

简单描述
型态特徵 | 形态测量图
背棘 (总数): 7; 背的软条 (总数): 9; 臀棘 1; 臀鳍软条: 9. Schismatogobius saurii can be distinguished by the following characters: pectoral fin with 14-15 rays; pectoral fins banded with rows of dark spots; first dorsal fin membrane posterior to spine 6
connected to base of spine of second dorsal fin; Anal fin with 1 spine and 9 rays; and ventral surface of head in male whitish and slightly pigmented on the mentum and frenum or entirely brownish (vs. ventral surface of head in female whitish with a blackish or brownish mentum (Ref. 116448).
Recorded from Indonesia in streams with moderate to fast flow in shallow areas of gravel and boulders at depth of 0.4-0.6 m, usually at low altitude (< 10 m), and sometimes with Schismatogobius bruynisi (Ref. 116448). On the other hand, specimens from Japan (as Schismatogobius ninja) were collected from the lower freshwater reaches of the streams, at 50 to 1,300 m from the upper limit of tidal fluctuations; on coarse sand and gravel bottoms of shallow areas (depth usually 5-30 cm) around rapids, a typical habitat was at the ends of the rapids (transitional areas from rapid to pool) with steady flow. This species usually stay on the bottom and often bury half of their body in the substratum, preferring substrates with free gravel granules which can be moved easily by water flow, and do not inhabit silty substrates. Body markings perfectly camouflage them on the gravel bottom of their habitats; thus, are hard to detect if they remain motionless. Occurs with S. ampluvinculus, and sometimes with Schismatogobius marmoratus, but the most abundant syntopic species was Rhinogobius nagoyae; other gobies, such as Stiphodon percnopterygionus, Sicyopterus lagocephalus, Glossogobius illimis and Luciogobius ryukyuensis and amphidromous pipefish, Microphis leiaspis, were also frequently observed with this species (Ref. 125666).
