From National Geographic:

On this episode, the crew has reached their last days at Guadalupe Island, and want to make the most of it. They catch one more female great white, Annika, and Dr. Domeier hopes that a blood sample from her will complete his Guadalupe breeding ground research. They also wrangle Apache, a male, a fighter, and their biggest shark to date. The record-breaking shark, measured 13 inches longer than their previous record-holding white shark capture, weighs approximately 4,225 pounds.

“Shark Men: Biggest and Baddest” premieres Sunday at 10pm ET/PT on the National Geographic Channel.
