Marine biologists have discovered a mako shark measuring potentially over 13 feet off the coast of California, possibly marking the largest of its species ever recorded. The discovery was featured in the "Biggest Mako on Earth" episode of Shark Week, which aired on the Discovery Channel.
The expedition, led by marine biologist Tristan Guttridge, was prompted by tourist reports of a mako shark exceeding 12 feet near Cabo San Lucas, Mexico. During the initial search, the team encountered two large mako sharks, measuring just over 11 and 12 feet respectively. While these were significant, they did not meet the criteria for the potentially record-breaking shark, as adult female makos can reach up to 12 feet.

The search then shifted to the cooler waters surrounding Catalina Island, off the California coast. As the expedition neared its end, a large female mako shark approached the team's boat, attracted by tuna bait. Using cameras while inside a steel cage for safety, researchers were able to observe the shark. Though an exact measurement was not obtained, documentary producer and marine biologist Kendyl Berna stated that it is "very possible that last mako broke the 13-foot ceiling."
"We know there are bigger makos out here," Berna added.
Clara Calatayud, who had initially spotted the massive shark, guided Guttridge back to the original sighting location. Guttridge noted that "The team that saw this shark, they've spent time in the water with these, so this was definitely a massive animal."
The 38th annual Shark Week programming began on July 26, with various shark-themed shows continuing for several days.
