how do corals reproduce sexually

To develop reef building corals, several restoration techniques exist based on sexual or asexual reproduction. 10.1126/science.aay7457. In asexual reproduction, new clonal polyps bud off from parent polyps to expand or begin new colonies. In: Advances in reef science.

Zoanthid Corals are a colony of one living organism that is connected, therefore they do not need to have two different genders to reproduce. The polyps can then reproduce asexually by budding off tiny jellyfish one or two millimetres across, which feed on plankton and gradually grow into full-size adult jellyfish. In sexual reproduction, many of the coral species have both an ovary and a testes, whereas some of them have separate sexes.
