Coral Larvae (IMAGE) Virginia Institute of Marine Science Caption Adult corals release free-swimming larvae as one means of propagating the next generation. Here are two larvae of Pocillopora damicornis, the coral species that Rivest and colleagues used in their experiments. The brown 'ribbons' are the algal symbionts, which enter the larvae before they are released from the adult corals. Credit © E. Rivest/VIMS. Usage Restrictions One-time use only.
