The great hammerhead shark is the largest variety of hammerhead shark. You can tell the difference between it and the other breeds by the shape of the cephalofoil; the great hammerhead shark's cephalofoil is mostly straight on the front.
I am a transplanted Canadian, living in the South! I have a husband, two small children who inspire many of my designs, and two cats. I crochet a lot, I sew a little, I knit even less.
