How to Identify Gobi Naga

To identify Gobi Naga (Gobiopterus chuno), look at these key features.

Physical Characteristics

Body shape

elongated

Coloration

Mostly translucent to semi-transparent, with a silvery sheen on the operculum and belly. Some individuals may exhibit faint, irregular dark spots or a lateral stripe, particularly when stressed or during breeding. The internal organs are often visible through the body wall.

Scale type

cycloid

Mouth position

superior

Distinctive features

Highly translucent body, Small size, typically not exceeding 3 cm (1.2 inches) in total length, Large eyes relative to head size, Two distinct dorsal fins, Pelvic fins fused into a suction cup-like disc

Dorsal fin

Two dorsal fins; the first dorsal fin has 6-7 spines, and the second dorsal fin has 1 spine and 6-7 soft rays. The first dorsal fin is typically higher than the second.

Tail fin

Rounded to slightly emarginate caudal fin.

Pectoral fin

Pectoral fins are relatively large and fan-shaped, with 14-16 rays.

Distinctive fins

Pelvic fins are completely fused into a prominent, adhesive disc, characteristic of gobies, used for clinging to surfaces.

Identification Tips

1. 1

   Translucency

   The most striking feature is its almost completely transparent body, allowing internal organs to be seen. This distinguishes it from most other small gobies.

2. 2

   Size

   Its very small adult size (up to 3 cm) is a key identifier, especially when considering other goby species.

3. 3

   Pelvic Fin Disc

   Like all gobies, the fused pelvic fins forming a suction cup are present, but its small size and habitat help narrow down identification.

4. 4

   Mouth Position

   The upward-pointing mouth (superior) is adapted for feeding on surface or mid-water prey.
