From Jennifer Marohasy<\/a><\/p>\n\n\n\n

By\u00a0jennifer<\/a><\/p>\n\n\n\n

According to the Bureau of Meteorology, it was going to storm on Sunday.\u00a0 Instead, the day broke calm and sunny.\u00a0\u00a0 And so, Jenn (not me, there is another one) and M-J from Keppel Dive, took a few of us around to the very exposed Wreck Beach facing due east.\u00a0\u00a0 This is the beach where you can get properly wrecked on Great Keppel Island \u2013 as the story goes.<\/p>\n\n\n\n

According to local legends there is gold here, buried somewhere in the sand with a shipwreck, or three.<\/p>\n\n\n\n

I found gold by way of a nudibranch, specifically\u00a0Chromodoris kuiteri<\/em>.<\/p>\n\n\n\n

Can you see the nudi, amongst the corals?<\/figcaption><\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Most striking when you drop down to the reef at the northern end of the bay is all the bleaching.\u00a0\u00a0 It is everywhere at the reefs fringing this island.<\/p>\n\n\n\n

\"\"
There is so much bleached coral along the wall that we swam from the beach east, northern end. Wreck Beach reef, Sunday April 21.<\/figcaption><\/figure>\n\n\n\n

What is not bleached seems to be a particularly dark chocolate brown: \u00a0it seems much of the coral either has no zooxanthellae or too much.<\/p>\n\n\n\n

Plate corals a very dark brown replete with zooxanthellae, contrasted against the stark white branching that is bleached.<\/figcaption><\/figure>\n\n\n\n
\"\"
Contrasting bleached versus dark brown corals, but these perhaps brown from macro algae rather than symbiotic algae.<\/figcaption><\/figure>\n\n\n\n
\"\"
What species of coral is this? It looks a healthy brown with purple tips. Wreck Beach reef, April 21, 2024.<\/figcaption><\/figure>\n\n\n\n

Can someone explain to me how this works, how does the zooxanthellae become toxic to the coral when the water becomes too warm? What is the physical mechanism?<\/p>\n\n\n\n

I\u2019m told that it is\u00a0not<\/em>\u00a0a case of the zooxanthellae dying insitu, rather the coral polyps kick them out.<\/p>\n\n\n\n

Leaving Wreck Beach reef, for Secret Cove. More about this secret and a shark in Part 4, tomorrow.<\/figcaption><\/figure>\n\n\n\n

Trying to remember the name of this fish. There were a lot of them here, and around the headland at Secret Cove.<\/figcaption><\/figure>\n\n\n\n
