How to catch Bonnethead

Sphyrna tiburo (Linnaeus, 1758)

About Bonnethead fishing

The bonnethead is a small coastal shark belonging to the family Sphyrnidae, immediately recognised by its smooth, spade-shaped head with the smallest cephalofoil of any hammerhead species. It features an elongated grey-brown body that fades to a lighter underside, reaching a common length of 80 cm and a maximum length of 150 cm. Distributed widely across warm littoral waters, it inhabits shallow estuaries, bays, and mangrove areas over soft mud, sandy expanses, and seagrass beds down to 80 metres. This active species moves in small groups, exhibiting a diel rhythm where it forages on shallow grass flats at night and retreats to deeper waters by day. It feeds primarily on benthic crustaceans such as blue crabs, molluscs, and small fish, and is uniquely known to digest plant matter like seagrass. Viviparous and non-territorial, it provides an energetic sport-fishing target for anglers using light tackle in shallow coastal zones.

How to catch Bonnethead

Tips for catching Bonnethead

Succeeding with inshore sharks requires targeting shallow grass flats, sandbars, and tidal creeks where individuals cruise during warm months. Because these fish hunt by scanning the sediment for crustaceans, presentations that mimic small scurrying crabs or fleeing shrimp near the bottom yield the best results. Look for dorsal fins breaking the surface during calm periods and cast ahead of moving groups, allowing the presentation to settle before giving subtle twitches. Early morning and late afternoon provide optimal activity windows when individuals move onto shallow flats to feed. Use light spinning gear or fly rods combined with fluorocarbon or light wire leaders to handle energetic runs without spooking fish in clear water.
