Hammerhead shark

The hammerhead shark is a fish you catch in the sea. Look for a very large, finned shadow. In the northern hemisphere look for it in Jun – Sep, from 4 PM – 9 AM. It can only appear after you have caught 20 fish. Nook's Cranny pays 8,000 Bells, C.J. pays 12,000 Bells.

A fin shadow in the sea from late afternoon until morning, once you have 20 catches. Night fishing along the coast in the warm months is your best bet; it sells for 8,000 Bells.
