Odontamblyopus lacepedii, also known as warasubo, is a species of eel goby found in muddy-bottomed coastal waters in China, Korea and Japan.

[1] The specific name honours the French naturalist and politician Bernard-Germain-Étienne de La Ville-sur-Illon, comte de Lacépède, publisher of the 5 volume Histoire Naturelle des Poissons who is reported to have illustrated this species under the name Taenioïde Herrmannien.

Warasubo is a popular dish in cities around the Ariake Sea in Japan, used to boost tourism.

In Korea, the fish is called gaesogeng (개소겡), but the regional name daegaengi (대갱이) is used more frequently in context with food.

It is a local specialty of Korea's south, e.g. in Suncheon (순천), Beolgyo (벌교) and Haenam (해남), where it is considered a delicacy.
