This is “Shredder”, aka “Scar”, a great white shark (Carcharodon carcharias) often seen at Guadalupe Island. In 2003 Shredder bit the anchor line of the Ocean Odyssey clean through, severing the boat from its anchor. He is named for his shredded dorsal fin. Shredder is about 13-14 feet long. Note that in this photograph he is sporting three satellite tags on his left flank just below his dorsal fin. They are covered with algae but are probably still operational. These tags collect information about his diving habits and water temperature and transmit this information to a satellite for use by researchers.
