Great Barracuda (Sphyraena barracuda)
This fish can be a bit un-nerving to the beginning snorkeler because of its opening and closing mouth, revealing large teeth. This is not a display of aggression, but rather a method to push water through the gills. When approached slowly they will linger allowing the snorkeler to get quite close (attracted to the snorkeler’s splash of the fins at the surface). It has a silver coloration, a long cylindrical body and occasional dark blotches on the side. Common throughout the region, Barracuda often travel alone and swim just off the reef. When encountered near a school of baitfish, the hunting behavior of this species can be exhilarating to watch and get your heart pounding. See the e-book.
