Note

Spermatophores produced by most calanoid copepods are simple, tube-shaped
flasks that contain the spermatozoa and seminal secretions. They adhere to the
external cuticle of the female by means of a cementlike substance present on the
tapered, open end of the flask. Other calanoids have evolved spermatophore
flasks connected to highly complex, chitinlike coupling plates. These have a
specific configuration that corresponds to the morphology of the conspecific
female's urosome, thus assuring proper placement. Spermatophore transfer is
accomplished by a ritua lized and precise mating behavior controlled by pheromonal
attraction and structurally modified copulatory appendages. The distinctive
morphologies of the spermatophores, copulatory appendages, and female
genitalia, in combination with species-specific mating behavior, function as
controlling factors of reproductive isolation in ca lanoid copepods.
