This little guy was swimming in Hoi Ha Bay (海下灣) in Sai Kung (西貢) back in 2002. It was not big, just a few inches long. It was colourful and looked harmless, seemingly just floating around nonchalantly. But I stayed out of its way anyway.
The place was beautiful. The water shallow and clear, and full of little creatures such as this little jelly fish, other small fish, snails, and more.It was also subtly dangerous. We waded out further and further, until at least 50 meters from the shore, and yet the water was still only up to our knees. Before we knew it, however, the tide changed. The water level started rising rapidly, and our shorts got wet. Fortunately we scrambled back to shore before it became really dangerous
