White abalone reproduce by releasing their eggs and sperm into the surrounding water, known as broadcast spawning. If fertilized, the eggs hatch after only one day, but high concentrations of sperm are required in order for an egg to be fertilized.
Most Hydra are gonochoric and both sexual and asexual (clonal) reproduction occur. Asexual reproduction is via asexual buds that form on the parent animal. They look like, and are, small hydras (Fig 1, 7-57) that will separate from the parent and adopt an independent existence. Hydra does not form colonies. Gonads form in the epidermis of mature animals. These are either ovaries or testes which produce eggs or sperm, respectively, by meiosis. Gonads are low conical mounds on the surface of the column, ovaries are larger than testes.
