With this double video shot in July 2016, we can see a young Nassau grouper hovering over the remains of an old wreck. We can already see that the dark and light longitudinal bands which are one of the characteristics specific to the Nassau grouper are already present in its juvenile stage.
On this other video shot in August 2017, two other main features of the Nassau grouper are present: on the one hand the black saddle-shaped spot on the caudal peduncle, on the other hand the crenellated profile of its dorsal fin with a 3rd thorny ray longer than all other rays
