Even corals living in some of the warmest ocean waters on the planet are susceptible to bleaching and heat stress, according to Australian researchers who studied unique tidal species in the Kimberley region.
When the water gets too warm, it breaks down the symbiosis between coral and their zooxanthellae (the microscopic plants which gives coral most of its colour), which can be fatal for the coral.
In the new study by scientists at the ARC Centre of Excellence for Coral Reef Studies said they were surprised to find that corals around the Kimberley region in north Western Australia are just as sensitive to heat stress and bleaching as their counterparts from less extreme environments elsewhere.
