Nudibranchs are my favorite underwater macro photography subjects. They are small, colorful, and sometimes hard-to-find amongst the reefs. Capturing a unique perspective is my main photography challenge, so that the image does not look like a textbook identification picture. This particular nudibranch posed for me by stretching out, showing off its rhinophores (tentacles on its head).
