These pictures were taken on the M.V. Capt. Keith Tibbetts, a (renamed) Russian frigate sunk intentionally off Cayman Brac as an artificial reef. Unfortunately, the batteries in my camera flash failed, so all my pictures on this dive were taken with available light. Hence the lack of colour, which is absorbed by the water.
This pair of permits was playing on the stern. Usually they are solitary, if you see them at all. Permits are considered an uncommon sighting in the Caribbean.
