features

Pungitius sinensis has a slender body, becomes 6.5 cm long and is similar in color to the nine-spined stickleback . There are six to eight enlarged scales on the sides of the body. Usually Pungitius sinensis has eight to eleven dorsal spines. The dorsal fin is supported by eight to twelve soft rays. The number of gill rakes is 10 to 14. In addition to one pelvic spine , there are also two associated soft rays on each side of the body. The caudal fin is usually rounded. Of the 33 to 35 vertebrae in the species, 14 to 15 are precaudal vertebrae.

distribution and habitat

Pungitius sinensis lives in very small bodies of water. Like all sticklebacks, it builds a nest of plant material just above the bottom of the water during spawning time and shows pronounced, sometimes very complex brood care behavior.
