When we look at the Red Sea, we can find corals that are more resistant to bleaching than other corals worldwide. But why is that?Corals in the Red Sea have to handle higher temperatures, yet they seem to grow and do just fine. The Red Sea is a very warm sea compared to other places. There, summer temperatures can reach up to 34°C, while other ocean waters may reach around 29–32°C. Interestingly, corals in the Red Sea are not only living in higher temperatures but also in higher salinityThe amount of salt in water, for example, in seawater. You can find a range of different salinities in the ocean, depending on the region. The Red Sea has some of the highest levels of salt.. Salinity is a measure of the amount of salt in the water, and the Red Sea has some of the world’s highest salt levels. That is why we started wondering whether salinity could be a piece of the puzzle and the ability to live in high salinity one of the secrets of the strong Red Sea corals?
