Cruises steadily along bays in search of food, moving in and out with the tides. Prefers low visibility - night, turbid water, overcast conditions. Known to aggregate possibly for mating. Preys on sharks and rays, bony fishes and marin. Broadnose Sevengill Sharks have been observed spy hopping - holding their heads above water and seeming to look around. This behavior is rare among sharks but has been regularly observed in Great White Sharks.
