These are the teeth that are responsible for all the beautiful white sandy beaches out there. Parrotfish eat coral and grind up the skeleton and excrete sand. How is this possible? A team of scientists subjected parrotfish beaks to a Berkeley X-ray machine known as the Advanced Light Source (ALS). The ALS can image organic crystals at a microscopic level. And the analysis revealed a unique woven structure in the crystals in a parrotfish's mouth that could open new frontiers for materials science, the researchers said. - http://bit.ly/2RGa3xT Peter: More evidence of sunscreen causing damage to coral. - http://bit.ly/2HrsBxl Listener Calls: Greg from Arizona with a question about water changes and his new sump.
