100626 Cyrene reef

Cyrene reef is a very special place in our southern waters, fill with an amazing collection of wildlife despite being in the middle of the 'Industrial Triangle'. Sadly, even this haven of biodiversity is fast succumbing to the ravages of environmental changes that threaten the lives of its inhabitants, the most apparent of the results being coral bleaching.
