Comparative sperm ultrastructure of three species in Siniperca (Teleostei: Perciformes: Sinipercidae)

- We investigated the comparative sperm ultrastructure of three species in Siniperca.
- All of the spermatozoa conform to the teleostean type II spermatozoa.
- There are significant interspecific differences and a comment was given.
- It brings fresh insights into phylogeny, biodiversity conservation and reproduction.
