More Info
Distribution |
Darwin area and Maningrida, Northern Territory. Elsewhere the species occurs in the tropical east-Indo-west Pacific. |
Features |
Dorsal fin VI + I,6-7; Anal fin I,6-7; Pectoral fin 13-16; Caudal fin segmented rays in 8/7 or 9/7 pattern; Lateral scale rows 23-27; Predorsal scales 6-7. A small Pseudogobius with 2–4 rows of cycloid scales on opercle; cheek naked; shoulder girdle with smooth narrow flange or smooth edge; tongue short, usually blunt; in males, teeth in outer row largest and widely spaced, slightly flattened and usually straight with pointed tips; in females, outer row teeth very small, close-set, evenly sized and usually blunt-tipped. First dorsal fin lacking filaments; large ctenoid scales on side. |
Colour |
Head and body translucent to pale yellowish with 5–6 diffuse greyish saddles on dorsum that may extend ventrally as indistinct bars and mid-side of body with five brownish blotches; on scaly base of caudal fin, two blackish rounded spots, placed above and below last mid-lateral brownish spot and broad half-moon shaped to vertical yellow bar extending from these dark spots onto caudal fin itself. |
Similar Species |
This species can be distinguished from its congeners most easily by the colour pattern of two black spots at the caudal-fin base and the associated semicircular to vertical band of bright yellow on the anterior part of the caudal fin which is usually otherwise transparent (lacking dark spots); the four diffuse narrow bars evenly spaced along the body, and its small adult size (19 mm SL). |
Etymology |
The specific name fulvicaudus is from the Latin fulvus (= yellow) and caudus (= caudal fin), in reference to the diagnostic bright yellow mark on the caudal fin base in adult males. |
