Rhinogobius is a genus of bony fish from the family Oxudercidae in the order of the goby-like . It is widespread in East and Southeast Asia and occurs in the Russian Far East, Japan, Korea, China, Taiwan, the Philippines, Vietnam, Laos, Cambodia and Thailand.
features
Rhinogobius species are 3.5 to 10 cm long and have a typical goby shape with an elongated, laterally not flattened body and a beefy, loud-mouthed head. Rhinogobius differs from other genera of the goby by the combination of the following features: The first dorsal fin is supported by 5 to 7 spiked rays, the second has a spiked ray and 6 to 11 segmented soft rays, the anal fin has a spiked ray and 5 to 11 segmented soft rays. As with most gobies, the pelvic fins lie on the chest under the pectoral fins and have grown together to form a funnel-shaped suction disc. The pelvic fins have a spine and five soft rays. The membrane, which together with the pelvic fins forms the suction disk, lies between the inner soft rays. The pectoral fins are supported by 14 to 23 segmented soft rays. The body is for the most part covered with comb scales, the snout, cheeks and gill cover are scaly. On the sides of the body, there are 25 to 44 scales in a longitudinal row and 7 to 16 scales in a transverse row. The spine consists of ten to eleven trunk vertebrae and 15 to 18 tail vertebrae, making a total of 25 to 29 vertebrae. On the “cheeks” there are sensory papillae arranged in longitudinal rows , only in Rhinogobius similis the papillae are arranged below the eyes in several short transverse rows.
Systematics
The genus Rhinogobius was introduced in 1859 by the American ichthyologist Theodore Nicholas Gill for a single species ( R. similis ), so it was originally monotypical . Today it is the most species-rich genus of freshwater gobies with over 70 species. There are also some previously undescribed species.
