The brightly-colored coral reefs that make scuba-diving and snorke領(lǐng) so enjoyable are essential to the survival of much underwater life.

Reefs offer protection to plants and animals from the ravages of waves and ocean currents. Thus, when the reefs die, so do many other living creatures. 高靈敏一體式熒光光譜儀-FluoroMax-4 模塊式熒光光譜儀-Fluorolog-3
