Scalloped hammerheads patrol the deep channel of Naingoro Pass, typically appearing as solitary adults or small groups at depths below 20 metres during slack water. The cephalofoil (hammer-shaped head) dramatically increases electroreception capability, allowing the shark to detect the electric fields of prey buried in sand or hidden in reef crevices. Their global populations have declined by more than 80% due to fin-trade fishing pressure, making pass sites like Naingoro Pass important reference points for regional conservation monitoring.
