With all of the disheartening talk about climate change and its negative impact on our seas, it’s reassuring to hear about one creature’s amazing ability to withstand the sea’s fluctuating temperatures. Scientists have found what they call “super reefs” off the coast of East Africa. What makes these reefs so “super”? Studies have found that this area near Tanzania experiences a higher fluctuation in currents and water temperatures than in other places. This variability in the water causes most reefs to bleach and die off. But not these super reefs. Scientists have found that these specific reefs actually sustained and grew back aftera major bleaching event in 1998 that destroyed 45% of the area’s corals. It’s not completely clear why they are so resilient to the water temperature fluctuations, but their complex structures may have something to do with it.

Another reason that these beautiful creatures have adapted to the ever-changing waters is due to fishing management. Restricted commercial fishing in the area has helped sustain the fish population. Fish are critical in the survival of reefs because they eat the algae that grow on them. Without these feeder fish, the algae can suffocate the reefs. Many people don’t realize that coral reefs are one of the most endangered species in the world, which is a disastrous situation since the reefs house 25% of all marine life. While it’s sad that these creatures have to adjust to climate change, it’s wonderful that they have the special ability to adapt to their surroundings!
