Female animals with cloacas receive sperm, lay eggs, and give birth through their cloacas. In some species, males secrete sperm through their cloacas, and mate by having the male and female cloacas “kiss” so that sperm transfer can occur. However, this is not universal: some cloaca-possessing species also have penises.
