I have seen these creatures infrequently and usually singly. We were swimming along and I found four – the fourth is just above on the coral and out of view. Maybe they were gathered to mate. They have rhino horns in the front and the frond in the back is for breathing. I read it somewhere. You want to have both ends in focus when you shoot. And I didn’t know there’s a footpod. Once again the first time you get an image you feel so lucky. After that you try for the classic image. No, I didn’t Photoshop and clone these three together.
