A scuba diver who was on a diving tour of great white shark habitats narrowly escaped an encounter with one this month when it broke through the bars of a diving cage and thrashed for nearly a minute until it freed itself.
The diver, Chan Ming, a Shanghai-based advertising executive who is a scuba instructor in his spare time, was among about 20 people on a five-day tour from Ensenada, Mexico, to Guadalupe Island. The main purpose was to see sharks, and Mr. Chan, 51, jumped into the water on Oct. 5 with a camera. He entered the cage hoping for a close-up.
During the encounter, which was caught on video and then shared across the internet, a juvenile great white leaps for a piece of tuna. Mid-leap, the shark slaps against the bars of the cage, entering and thrashing while Mr. Chan is trapped inside.
