What is a spermatophore?

A spermatophore is a packet or capsule containing sperm, produced by male organisms in various animal groups, including some arthropods, mollusks, and amphibians. It serves as a means of transferring sperm to the female during mating, ensuring successful fertilization. The structure and function of spermatophores can vary widely among species, reflecting their reproductive strategies. In some cases, males may deposit spermatophores in the environment for females to pick up, while in others, they may directly transfer them during copulation.
