Additional Notes

The Smallest Hammerhead species usually found in Public aquariums. And the only species which can potentially be kept in large private aquariums - provided the owner has a tank/pond that is the size of good size swimming pool. Also Bonnetheads becuase of the shape of their heads need a tank/pond that has no sharp corners - a round or oval design is best suited for this species.
