Within the last decade infestations of the crown-of-thorns starfish (Acanthaster planci) have been reported from all over the Pacific and the Red Sea. Nearly all of the infestations are near centers of human population. It is postulated that chemical pollution, most likely in the form of chlorinated hydrocarbon pesticides such as DDT, is responsible for the increased populations of A. planci. The localization of the infestations of A. planci is probably the result of teh chance combination of many factors such as a successful spawning of the starfish, the correct rtemperature for development, and the transport of the larvae i a current system to a suitable inshore environment for settlement. The excessive populations of sea urchins in the coastal waters of southern California may also be a comparable effect of chemical pollution.
