White sharks don’t have fingerprints—but they do have unique scarring patterns on their dorsal fins, which our white shark researchers use to tell them apart. Sometimes they name sharks after familiar profiles they spot in the fin patterns. Can you guess what they named this recently-spotted shark?

Researchers track the same white sharks returning to feeding grounds year after year. The record belongs to a shark called Elvis, first spotted in 1989. Elvis has returned for 27 straight seasons!
