text: Well, most likely the mothers were not around. Hammers are a strange breed. They school a lot during the day, mostly small to medium.(credit of the lines below go to: .geocities.com/RainForest/Andes/1151/)\n\nAnother unusual thing hammerheads do is form schools. These schools can contain hundreds of individuals, with the largest known schools containing as many as 500. The reason why hammerheads school and other sharks do not is unknown. Hammerheads only school during the day. They break up at night to do their feeding. Because the schools contain mainly small to medium sized hammerheads, it is believed that they school to reduce the risk of predation from larger sharks. It is also believed that an order of dominance exists in the schools based on age, size and sex. \n\nI have attached a few links of my favorite hammer sites\n\nEnjoy and good to hear you took your family out fishing
