Symbionts Impact the Behavior of Coral Larvae

by Kimberly Coombs

Climate change is known for causing adults corals to become bleached, but it is also affecting the early life stages of corals. The larval stage of a coral reef’s lifecycle is very important to its survivorship. Corals disperse their larvae out into the water, then the larvae are responsible for finding a suitable substrate to settle on. After settlement, corals are able to start growing accumulate symbionts. Several studies have observed how different symbionts influence juvenile coral growth rates and thermotolerance; however, no data currently show if there are any influences from symbionts on the coral larvae before settlement occurs.
