When I started diving, like most people, I liked to spot large animals such as turtles, sharks, manta rays and whale sharks. But after several years, I started to search for smaller creatures. Amongst these, my favourites are nudibranchs (pictured here), ghost pipefish, pygmy seahorses, flatworms and gobies. I particularly like to spot juvenile fish, such as oriental sweetlips and batfish, because the colours and patterns on their bodies are different from those of adults.
