In this week’s Wild Oceans, we explore the untouched reefs of the Philippines in ultra high definition. A beautiful lionfish shows off its venomous spines, tiny shrimp scuttle across an anemone, and we take a close-up look at a vividly coloured nudibranch. There’s even a ‘mystery fish’ that has our seasoned underwater cameraman scratching his head. Can you identify it? Let us know in the comments below!
