The reproductive tracts of most teleosts are specialized for the production of large numbers of gametes that undergo fertilization and development in the external environment.
Female teleost have ovaries with a central cavity which collects large numbers of ova before they are expelled via an oviduct to a genital pore. The ova lack the characteristic follicular development seen in mammals.
Male teleosts have testes which may vary in size with the breeding period. The sperm are delivered from the seminiferous tubules to the external environment via a sperm duct which may join the most caudal end of the urinary (archinephric) duct in some species. |
