How do corals evolve into separate species when their larvae can drift around the ocean over extremely long distances?

Corals in the genus Acropora generate much of the structural complexity upon which coral reefs depend, but they are susceptible to damage from toxic seaweeds. Acropora nasuta minimises this damage by chemically calling goby fishes who within minutes start chomping on the seaweed.

Jobs, ecotourism and diving industries can benefit from having a diverse supply of weed-eating fish on the world’s coral reefs, scientists say. Despite their small size, relative to the sharks and whales that often get more attention, herbivorous fish play a vital role in maintaining the health of coral reefs, which support the livelihoods of 500 million people worldwide, according to a study published this month in the journal Ecology.

Nearly one-third of CO2 emissions due to human activities enters the world's oceans, making them less alkaline and affecting calcification of corals. By the middle of the century, corals at the Northern edges of the tropics will be in trouble with the Hawaiian island reefs will be among the first to feel the impact.
