Puntius khohi markings on the lateral line scales and the lateral line is complete and is little concave with 28 scales and a light band above the lateral line. black markings are present in caudal peduncle, operculum and dorsal fin is black in shade. Biodiversity of the river in which "P.khohi" is present is threatened by illegal fishing using poison. Puntius khohi Puntius khohi is a species of fish in the family Cyprinidae in Puntius genus.

Operculum (fish) over time. The fossil record of the threespine stickleback provide the ancestral shapes of the operculum bone. Overall, the operculum bone became more triangular in shape and thicker in size over time. Genes that are essential in the development of the opercular series is the Eda and Pitx1 genes.These genes are known to be a part of the development and loss of armor plates in gnathostomes. The Endothelin1 pathway is thought to be associated with the development of the operculum bone since it regulates dorsal-ventral patterning of the hyomandibular region. Mutations in Edn1-pathway in zebrafish are known to lead to
