Schools of scalloped hammerheads congregate at the seamount primarily from October through February, drawn by the nutrient upwelling that concentrates their cephalopod and fish prey. The distinctive cephalofoil head houses a vastly expanded electrosensory system that helps them detect prey buried in sediment — on seamounts they use this sense to navigate magnetic anomalies. Juveniles develop in nearshore nurseries while adults undertake deep oceanic migrations.
