Florida Shark ID: Blacktip, Spinner, Bull, Lemon, Bonnethead

By the Fish Scouter team ·

Most Florida shark IDs come down to a few marks: the anal fin (black-tipped on a spinner, plain on a blacktip), the snout (short and blunt on a bull shark), the two dorsal fins (nearly equal on a lemon shark), the barbels (only the nurse shark has them) and the head (shovel-shaped on a bonnethead, hammer-shaped on the hammerheads). Several common Florida sharks, including the lemon, tiger, sandbar and all hammerheads, are prohibited by FWC and must stay in the water.

Getting it right matters. A wrong ID can mean keeping a protected shark, or hauling one up the beach that should never have left the surf. Here's how to tell Florida's common sharks apart, what the rules require when you hook one, and how to release a shark so it swims away.

The status column reflects FWC's list as we read it in November 2026. Rules change. Before you keep any shark, read FWC's shark regulations for the current list, sizes and limits.

Blacktip vs spinner shark

This is the ID Florida beach anglers get wrong most often. Both are grey, both have black-tipped fins, both jump, and both run the beaches with the mullet and the bait pods. According to the Florida Museum of Natural History:

  • The anal fin is the giveaway. Adult spinner sharks have a black-tipped anal fin. Adult blacktips usually don't.
  • Dorsal fin position. The spinner's first dorsal fin starts well behind the rear tips of the pectoral fins. The blacktip's sits just behind where the pectorals attach.
  • Snout. The spinner's snout is long and pointed.
  • Teeth. Spinners have narrow, upright upper teeth; blacktips have larger, broader upper teeth.

Young spinners may not have the black anal fin tip yet, so on a small fish, look at the dorsal position too. The jump helps: a spinner corkscrews up out of the water when it's hooked, while a blacktip tends to jump and fall.

Bull shark

The bull shark is the heavyweight of Florida's inshore water. The Florida Museum describes a blunt, rounded snout much shorter than the mouth is wide, a large, broadly triangular first dorsal fin, no interdorsal ridge, and pale to dark grey coloring. Bull sharks are one of the few sharks that move readily into fresh water, which is why you'll find them in the Caloosahatchee, the St. Lucie River and the canals of South Florida as well as in Boca Grande Pass and under the bridges.

The common mix-up is with the sandbar shark, which is prohibited. Run a finger along the back between the two dorsal fins: a sandbar has a ridge there, a bull doesn't. A sandbar's first dorsal is also taller and set further forward.

Lemon shark

The lemon shark's yellow-brown color is the first clue, but the surest mark is the two dorsal fins. The Florida Museum describes them as triangular and close to the same size; on most other sharks the second dorsal is much smaller. The snout is blunt and shorter than the mouth is wide. Lemon sharks cruise the flats, mangroves and reefs of South Florida and the Keys, and big schools gather off the Atlantic beaches in winter. They're prohibited in Florida.

Nurse shark

Nurse sharks are the easiest Florida shark to identify: a pair of barbels hanging from the nostrils, a small mouth at the tip of the snout, a brown body and two rounded dorsal fins set far back on the body. The tail is long and has no real lower lobe. They're nocturnal and rest on the bottom by day under ledges and docks. They're slow, but they're not toothless; handle them with care.

Bonnethead

The bonnethead is a small hammerhead relative with a smooth, rounded, shovel-shaped head. It lives on grass flats, eats crabs and shrimp, and is the first shark many Florida kids catch on light tackle. If the head is shaped like a shovel rather than a hammer, it's a bonnethead.

Hammerheads

All three large hammerheads in Florida, the great, the scalloped and the smooth, are prohibited, so you only need to know it's a hammerhead to know what to do: keep it in the water and release it fast. Telling them apart, per the Florida Museum:

  • Great hammerhead: the front edge of the head is nearly straight with a shallow notch in the center, and the first dorsal fin is very tall and sickle-shaped.
  • Scalloped hammerhead: the front edge is arched with scalloped indentations and a center notch.
  • Smooth hammerhead: the head is like the scalloped's but has no center notch.

Hammerheads tire quickly and are prone to dying after a long fight. Use heavy tackle, keep the fight short, and cut the leader close if needed.

The rules when you hook a shark

FWC's current shark rules (always confirm at MyFWC) include:

  • Shore-based Shark Fishing permit: anglers 16 and older who fish for sharks from shore, including from piers, bridges and the beach, need this free permit. You get it by taking FWC's online Shark-Smart Fishing course, and it must be renewed every year. It also applies to shore anglers targeting other fish with heavy shark-style gear such as a long wire leader or a fighting belt. No permit is needed from a boat.
  • Prohibited species stay in the water: FWC says prohibited sharks must remain in the water with the gills submerged, whether you're fishing from shore or from a boat. From shore, release them immediately; don't drag them onto the sand beyond the surf zone, a pier, a bridge or a boat.
  • Cut the leader if you need to: if removing the hook would delay the release, FWC says to cut the hook or leader as close to the hook as possible.

Size limits, bag limits and gear rules (such as required circle hooks with natural bait) apply to the sharks you may keep. We don't repeat the numbers here because they change; check FWC.

How to release a shark in the water

  1. Use heavy enough tackle to end the fight fast. A long fight exhausts a shark and can kill it after release.
  2. Use circle hooks and a non-stainless hook if you can. Circle hooks usually catch the corner of the jaw, making the release quicker.
  3. Keep it in the water. From the beach, work the shark into the shallow surf with its gills submerged. From a boat, keep it alongside.
  4. Take the photo in the water. A quick picture with the shark beside the boat or in the wash is the trophy.
  5. Use long dehookers or cut the leader. Keep your hands away from the mouth. A shark can bend its head back further than you'd think.
  6. Revive it if needed. Hold it facing into a gentle current until it swims off on its own.

Not sure what you caught?

Take a clear side-on photo showing the fins and the head. Fish Scouter's photo ID suggests up to three matches from the species in our book with the marks it used, and each match opens a species card with the FWC rule link. For a tricky shark, compare it with the table above before you decide anything. Our guide to identifying a fish from a photo has tips for getting a useful shot.

Questions anglers ask

How do you tell a blacktip from a spinner shark?

Check the anal fin, the small fin on the belly in front of the tail. Adult spinner sharks have a black tip on the anal fin; adult blacktips usually don't. The spinner's first dorsal fin also starts further back, behind the pectoral fins, and its snout is longer and more pointed.

Which sharks are prohibited in Florida?

FWC's prohibited list includes the great, scalloped and smooth hammerheads, lemon, tiger, sandbar, dusky, sand tiger, silky, Caribbean reef, both makos, white and whale sharks, among others. The list changes, so check MyFWC's shark page before you fish. Prohibited sharks must stay in the water.

How do I identify a bull shark?

A bull shark is thick and heavy, grey on top, with a very short, blunt, rounded snout that's shorter than its mouth is wide, a large triangular first dorsal fin, and no ridge on the back between the dorsal fins. It's the shark most often found in brackish rivers and passes.

Do I need a permit to shark fish from shore in Florida?

Yes, if you're 16 or older. FWC requires the free Shore-based Shark Fishing permit, earned by taking an online course and renewed every year. It also applies to some shore anglers targeting other fish with heavy shark-style gear. No permit is needed from a boat.

What's the most common shark in Florida?

For inshore and beach anglers, blacktip sharks, bonnetheads and Atlantic sharpnose sharks are among the most often caught. Bull sharks are common in the passes, rivers and around bridges, and nurse sharks are common on Keys reefs and ledges.
