Bonnethead Sharks are one of the most approachable and entertaining sharks we see along the North Carolina coast. They’re a smaller member of the hammerhead family with a shovel-shaped head, streamlined body, and a serious fondness for crabs and shrimp. On light tackle they pull far above their weight class, making them a favorite for families, beginners, and anyone who enjoys steady action in shallow water.
Around North Carolina, Bonnetheads are most commonly encountered in inshore waters, tidal flats, sandy bays, shallow channels, and near inlet mouths, especially over clean sand or mixed sand-and-grass bottom. They’re classic “shallow water” sharks, cruising across bars, edges, and flats where small crabs, shrimp, and baitfish are plentiful and the current sweeps food along with each tide cycle.
Most of the Bonnetheads we see in NC fall in the 2.5–4 foot range, commonly weighing 10–20 pounds, with the occasional larger fish showing up when water temperatures peak in late summer. They’re big enough to put a good bend in the rod, but manageable enough that kids and newer anglers can fight and land them with a little coaching.
Bonnetheads sit in an interesting spot when it comes to records. They were historically included in North Carolina’s coastal shark record listings, but the current state saltwater records table does not show a clearly broken-out bonnethead-specific entry. Any past listings date back to years when the category was tracked separately. On the world stage, the IGFA all-tackle world record Bonnethead Shark weighs 28 pounds, caught by angler Carter Wells on June 28, 2012, in the Halifax River at Port Orange, Florida — a fish that also claimed the Male Junior and Men’s 30-lb line-class world records.
This page breaks down everything you need to know if you’re trying to identify a Bonnethead Shark or understand how they behave along the NC coast. Whether you’re learning the species for the first time or checking off sharks you’ve caught over the years, this guide will walk you through the key traits, where they show up, and what makes them such a fun part of our shark fishery.
Bonnetheads are often confused with “baby hammerheads,” but they’re their own distinct species with a much smaller, more rounded head and a very different lifestyle. Instead of roaming far offshore like some of the bigger hammerheads, Bonnetheads spend a lot of time on shallow flats and edges, rooting around for crabs and shrimp in just a few feet of water.
For anglers interested in Bonnethead fishing in North Carolina, most of our encounters happen in and around inlets, shallow bays, and nearshore surf troughs, especially in late summer and early fall when the water is warm and small crustaceans are abundant.

Bonnethead Shark Identification
Bonnethead Sharks are the smallest of the hammerhead family in our region and are easy to recognize once you know what to look for. Instead of the wide, wing-like head of a great or scalloped hammerhead, Bonnetheads have a smooth, shovel-shaped “spade” head that looks more rounded across the front. Combine that with their modest size and slim, quick-moving body, and they stand out from other coastal sharks once you’ve seen a few.
- Head & eyes: Bonnetheads have a distinctive rounded, bonnet-shaped head (cephalofoil) with the eyes set out near the tips. Unlike larger hammerheads, the front edge of the head is curved and smooth rather than strongly notched or T-shaped. This is the single best ID feature when you see one from above.
- Body & fins: The body is slender and streamlined, built more for speed and quick turns than brute power. They carry a moderately tall first dorsal fin with a smaller second dorsal and pelvic fins, giving them a balanced profile without the bulky, blocky look of a Bull Shark.
- Tail shape: The tail has a pronounced upper lobe and a smaller lower lobe, suited for sudden bursts and fast, darting movements as they chase down crabs, shrimp, and small fish over sand and grass.
- Color & markings: Bonnetheads are usually a light gray to olive-gray on top with a pale, whitish underside. Some fish show faint shading near the fins, but they lack bold bars or spots. In clear shallow water they can appear almost bronze over sand.
- Teeth & diet: Their teeth are small and rounded compared to many other sharks, reflecting a diet that’s heavily focused on crabs, shrimp, and other crustaceans. They’re one of the few shark species known to regularly digest seagrass along with their normal prey.
- Most common in NC: Along our coast, Bonnetheads are most often encountered over shallow sand flats, bay mouths, surf-zone troughs, and inlet channels with plenty of crabs, shrimp, and small baitfish. If you’re fishing a clean sand flat that holds blue crabs and grass shrimp, there’s always a chance a Bonnethead will cruise through.

Where to Catch Bonnethead Sharks in North Carolina
Bonnetheads are classic shallow-water sharks that thrive anywhere warm water, clean sand, and crustaceans come together. In North Carolina, that means they’re strongly associated with inlets, sandy bays, and nearshore surf troughs where tides sweep crabs and shrimp across flats and channel edges. We often encounter them while fishing light bottom rigs for a mix of species in just a few feet of water.
- Inlets & bay mouths: Tidal deltas, bar edges, and channel mouths around major inlets are prime Bonnethead territory. These areas funnel bait and small crustaceans back and forth with each tide, and Bonnetheads cruise the edges picking off easy meals.
- Shallow flats & sandbars: Bonnetheads love shallow sand and mixed sand-and-grass flats, especially those that hold small blue crabs and shrimp. Flats adjacent to deeper channels or cuts can be especially productive on a moving tide.
- Surf-zone troughs: Deeper pockets and troughs just off the beach can hold Bonnetheads in late summer and early fall, particularly when grass shrimp and small crabs are thick in the wash. Long, smooth troughs with steady current are worth a serious look.
Across most of North Carolina, the prime window for encountering Bonnetheads lines up with the late spring through early fall warm-water season. The most consistent action typically falls in late summer and early fall when water temperatures are high and crab and shrimp activity is at its peak. On my charters, we treat Bonnetheads as a bonus species whenever we’re fishing shallow, sandy areas with plenty of life.
Best Shark Rigs & Baits for Bonnetheads in NC
My Go-To Shark Fishing Rig:
When we’re set up for a mix of coastal sharks, I often use the same heavy bottom rig that handles our larger species — a five-foot modified Carolina rig built in two sections: an upper section with a heavy, fixed sinker locked between two ball-bearing swivels, and a lower section consisting of roughly four feet of 400-pound monofilament leader running to a non-stainless inline circle hook.
That rig is more than enough for a Bonnethead and is what I rely on when there’s a chance of hooking bigger sharks in the same area. If we’re specifically targeting Bonnetheads on lighter tackle, I’ll often scale down leader size and hook size to better match their smaller mouth and the crab-and-shrimp baits they prefer — but the basic layout of a short, abrasion-resistant leader, strong circle hook, and bottom-oriented sinker stays the same.
The shark rig shown above is the exact one I use on most of my NC Shark Fishing Charters, and you can see how I build it step-by-step here: How to Make the Shark Fishing Rig I Use on My Charters.
My Go-To Baits for Bonnetheads:
Bonnetheads are specialized feeders that key in heavily on crustaceans. Fresh crab and shrimp baits are hard to beat, especially when you’re fishing them over the same sandbars and flats where those prey naturally live.
- Fresh blue crab (small or cut pieces) — a classic Bonnethead bait, especially over sand and grass flats near inlets and bay mouths.
- Shrimp — fresh or carefully thawed shrimp fished on the bottom in shallow channels, troughs, or along bar edges where current is moving.
- Small pieces of squid or cut bait — useful when you’re mixing in other species or when crabs are especially thick and picking at your baits.
- Match the hatch: If you’re seeing lots of small crabs or shrimp in the shallows, downsizing your bait and tackle to match that natural forage will usually get more bites.
- Note: Always check local bait and bait-fishing regulations before fishing, and keep your bait sizes realistic for the gear and anglers on board — especially when kids are fighting the fish.
Captain's Note: I think of Bonnetheads as “crab hunters with fins.” If we’re fishing a shallow flat with plenty of small crabs and shrimp, I’ll often rig one or two rods specifically with smaller crab or shrimp baits on lighter tackle. It’s a great way to keep younger anglers engaged and put steady bends in the rods while we wait on a bigger shark bite.
