This is the first report of estrogens in scleractinian corals. Seawater and egg slicks were collected during a mass coral spawn at Ningaloo reef, Western Australia for the measurement of total phosphate (TP) and E2. Total P in the water column increased 600 times, from 0.5mgrM to 300mgrM. Concentrations of E2 increased nearly 8 fold during the spawn, from 55 to 420 pg/100 ml seawater. Coral eggs collected from egg slicks contained 368±40 pg E2/g dry wt of eggs. Estrogen may be a key hormone in a simple endocrine system of scleractinian corals that synchronizes growth and development of coral oocytes. Its potential role in triggering spawning via chemical messengers in the water column warrants further research.</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record></records></xml>
