Abstract
THE hammer-head sharks present one of the most extraordinary modifications of form known among fishes, a puzzle defying explanation. The sides of the head are produced so that it is more or less hammer or kidney-shaped, and the eyes are placed at the extreme outer edge of each extension of the head. Some of these sharks attain a large size and are ravenous creatures greatly feared in some regions. I have seen none more than 4 meters in length, but they attain a much greater size. To see a hammer-head shark 3 or 4 meters long, with its strange and extraordinarily expanded head a meter and a half or more in width, is enough to give any one a thrill. The young are caught in numbers in many localities and are common in the markets in the Philippines, Dutch East Indies and the coasts of Hindustan.
