I Freedive to find silence and to get a better look at pollution, in the ocean. This is my way of learning and receiving first hand experience of life in the ocean, great and small. Here I swim in caves and swim throughs, beneath huge boulders, to check on the life inside. (All done on One Breath)
Here’s some info about Coral for your day.
Corals are not plants or even rocks. They are colonies of small animals, known as polyps, living closely together with minute single-celled plants called zooxanthellae. This is known as mutual symbiosis as both the corals and the zooxanthellae benefit from the association.
The corals receive "food" from the zooxanthellae when they photosynthesise and in return the corals supply the zooxanthellae with ammonia and phosphate from their waste metabolism.
The transfer of these waste products to the zooxanthellae is crucial for their survival as inorganic nutrients are almost absent in the surrounding water.
Corals under threat
The world’s coral reefs are under threat. Coral bleaching is caused by increased sea surface temperature, high levels of ultra-violet light, high turbidity, sedimentation and abnormal salinity. The algae that live in the polyps die and the corals turn white, becoming more vulnerable to overgrowth, disease and reef organisms that bore into the coral skeleton and weaken the reef structure.
