Great hammerhead shark
Great hammerhead sharks are around 2.85 to 5.5 meters long, and weigh around 450 kg, but the longest ever found was 6.1 meters long. The heaviest ever found was a 4.4 meter long female, which weighed 580 kg, and was caught off Boca Grande, Florida. But the female weighed this much because it was pregnant. The top part of the great hammerhead is gray-brown or green, and the belly is white.
