Show notes

[Sorry folks, notes will be brief for this episode. I have committed full time to a new project, so sadly I can’t write more here.]

I knew little about corals. I have a silly fear of the depths so I’m as likely to dive off a boat as I am to dive off a plane – I’ve done both once, and that’s enough for me.

But that’s my loss. In the shallow seas in Southeast Asia, off the coasts and around the islands,  there is a rich world of coral reefs filled with vibrant, diverse and colourful marine life.

The Coral Triangle, a region that spans from the Philippines to Java in Indonesia to Papua New Guinea, houses almost 80% of the world’s coral species. In turn, these coral reefs support thousands of species of fishes, mollusks, shrimps…etc.

However, the reefs are threatened. We often hear about corals dying in a warming sea. How does that happen?

More importantly, I want to act to save the corals. What can I do?

I want to know more without getting into the sea. Are corals animals or plants? How do they breed? Why are dead corals always white?

So, I invited marine biologist Dr James Tan Chun Hong to give me all the answers. He studies corals and is particularly keen to study how coral spawn, or reproduce.

James contributed to a Coral Spawning Database that was published in January.
