Hammerhead sharks are in danger of extinction as they are fished for their fins. The unusual configuration of the head and `hammer` are thought to be an evolutionary advantage that distances their eyes from the mouth and prey. Big schools like this are now a rare sight as they are fished in most areas of the oceans
