Robert: I just can't live away from the seashore. I need to dive at least once a week as marine biology fascinates me.
Zora Yin: I can't really quite understand your fascination with marine life nor oceanography.
Robert: The ocean habitat and the deep sea are so varied, colourful and serene! Coral reefs are exceptional!
Zora Yin: But it is also a very dangerous environment and ecosystem! Jellyfish look so nice but can be deadly!
Robert: Oceans are like any other ecosystem or environment with predators and prey.
Zora Yin: Stay away from sharks and predators when you dive, I love you too much!
