Mutton Snappers
Mutton Snappers are everywhere in the JDR, and plenty are found and caught on the flats- a real rarity. This is perhaps the best (and only) place in the world where you can now expect to catch mutton snappers on the flats. They are high powered fish that will pull with dogged determination when the safety of the mangrove roots is within sight. Mutton snappers are extremely wary when out on the flats, but if you can get the cast in there without spooking them, they are suckers for taking a fly. Most muttons caught on a fly run between three and eight pounds, but fish right up to fifteen pounds are a distinct possibility.

Jack Crevalle and Horse Eye Jacks
Jacks are wonderful game fish, and are very abundant in the JDR.  It is common to see a school of big jacks patrolling the flats, eating everything in sight.  Many of these fish are in the fifteen to twenty pound class with some right up to the thirty pound mark. They look somewhat like the permit, being in the same family, but Jacks are one of the most aggressive feeders on the flats and very easy to catch in relation to permit. As a bonus, the Horse Eye jacks make wonderful sashimi back on the boat before dinner.Cudas and SharksBig Cudas are plentiful around all the bonefish flats. Most will be three to four feet long, and will give any fly angler a terrific fight. Their aggressive take is exciting and few fish can swim faster or jump farther than a big barracuda.  They are easy to catch on the many good needlefish patterns, using a wire leader.

Silky Sharks
Silky Sharks and Caribbean Reef sharks are very common on the flats. You will see some surprisingly large sharks in shallows, looking for bonefish or anything else they can catch. Most are three to five feet in length, but you'll also see larger sharks in the seven to nine foot range. All of these will take a fly and the action can be spectacular. Good sized flies like divers utilizing soft foam popper heads, get their attention when popped aggressively in front of a shark. Sharks up to 150 lb. have been landed by fly anglers. Seeing one of these monsters roll up to the surface and smash a popper is sure to get your adrenalin flowing.

Other fish.  
Anglers that want to try trolling off the reef with plugs, bait, and even flies encounter many other species of fish. Various snappers including the huge Cubera Snapper are present as well as groupers, jacks, kingfish, albacore, wahoo, and bonito and big cudas. One group of visiting anglers caught twenty five different species of fish off the reef-in one day!
