Cal Ripfin (Shredder) right side profile

The G.O.A.T. of Guadalupe, the legendary Cal Ripfin/Shredder, with his trademark damaged dorsal fin on full display. While his dorsal fin is an easy way to identify Cal/Shredder, due to the fact that it's a permanent injury, there are many other reliable markings that we could use to identify him.

Cal has white markings behind both of his eyes that are fairly unique. The lower lobe of his caudal fin also has very unique white markings. There is also a permanent spot of dark pigmentation just behind the right corner of his mouth, which is very unusual for a white shark. This dark marking is not to be confused with the “dark spots” caused by clusters of parasitic copepods that are commonly seen on white sharks, which are thankfully non-permanent and NOT a reliable long-term identifier. 

Of course, when all else fails, we can also rely on the the countershading pattern where the grey pigmentation meets the wait. This can be used to identified any white shark, as the pattern is unique across every individual.
