Marty’s photo of the day #4504: The fish on top is a Bermuda chub, and the one below it is most likely an immature bar jack. During the many times Deb and I snorkeled this part of the reef, I saw this pair often. If I didn’t have a camera, I would have assumed I was watching an adult and a juvenile of the same species. Now, with a photo confirming they are different, I wonder if there is a symbiotic relationship going on here. Is the bar jack shadowing the Bermuda chub because the larger fish provides some protection?
