Bleaching

Bleaching occurs when corals expel their symbiotic zooxanthellae - pigmented, algae-like protozoa that live within the coral's cells. High temperature, pollution or other stresses can cause the coral to expel its zooxanthellae, leading to a lighter or complete loss of color.

Recent Activity

    mantas at Mauan on 21 May

    It was swimming around a small cleaning station, occasionally feeding. We think it was a pregnant female. We encountered a total of 4 mantas, one was around 2 meters and the others at about 2.5 to 3.5 meters.
