Anilao, Luzon Island, Philippines
This is commonly known as a Long-Horned Cowfish (Lactoria cornuta). Because they are such slow swimmers cowfish are easily caught by hand, making a grunting noise when captured. Their bodies are very stiff, since their scales are fused together to form a solid shell which covers almost the entire body. This one was photographed in about 20 feet of water on a night dive.
