What are Coral Reefs? Coral reefs are reefs consisted of coral consolidated into limestone. They are made of thin layers of calcium carbonate. Stony corals‚ or scleractinians‚ are the corals primarily responsible for laying the foundations of‚ and building up‚ reef structures. Immense reef structures are formed when each individual stony coral organism‚ or polyp‚ secretes a skeleton of calcium carbonate. How are corals classified? Corals are classified as animals although they may resemble plants

decreased drastically. Coral reefs are home to more species than all other marine environments‚ and many other species rely on the coral reefs for their own survival. Today coral reefs face multiple threats such as pollution‚ unsuitable fishing practices‚ global climate change‚ and other human activities.

it. Coral reefs get hit hard by the temperature of the water getting warmer. “Warming of as little as 1°C causes coral bleaching‚ a state in which the tissues of the coral become colorless because of the loss of the zooxanthellae”(Hoegh-Guldberg‚Donner‚pg. 9‚ par 3). This bleaching can stress the reefs and this can effect important functions of the coral. “Moderate bleaching results in stress that causes reduced growth rates and reproductive output‚ whereas severe bleaching results in coral death
