This beautiful Squirrelfish was spotted (with quite a few others) whilst recently snorkeling in Jamaica. These fish chose a home amongst the corals and rock crevices which they become very territorial about. They get incredibly defensive when someone infringes upon their space and will issue warnings by grunting and making other high pitched noises (which I obviously cannot hear underwater). For those of us who are hard of hearing, this fish also threateningly raised the spines along its back to let me know that I got too close. Once it realised I was a friend it went back to happily swimming laps around the coral and posing for some more friendly photos too. Because this fish stays close to its territory all the time it meant that I could find the exact same fish in the same location the next day. Click here for other underwater posts.
