Abalone Diver Severely Bitten by 5.5-Meter Great White off San Miguel Island

This well-documented case, investigated by Ralph Collier and published with forensic detail, involved a great white shark estimated at 5.5 metres based on tooth-impression analysis of the wetsuit and equipment, placing it among the larger reliably recorded individuals; additionally, the first-aid responder, Kenny Gray, had himself survived a white shark bite off Purisima Point in 1972, a remarkable coincidence with strong archival value.

On the morning of October 18, 1976, Jay Worrell, an experienced 29-year-old commercial abalone diver, was conducting a hookah dive approximately 10 to 15 meters from his support boat, the Karen II, near San Miguel Island in Santa Barbara County, California. Operating at depths between 30 and 35 feet, Worrell was gathering abalone when he was suddenly seized on his right hip and buttocks by a great white shark estimated at 5.5 meters (18 feet) in length. Worrell recalled the attack vividly: "I felt a vise-like pressure on my side for about 10 seconds, then my air hose was cut and bubbles went everywhere." The shark's bite severed his critical air supply, forcing an immediate emergency ascent. Upon reaching the surface, Worrell signaled for help while the shark remained nearby, its mouth opening and closing as if attempting to dislodge something. When the animal approached again, Worrell struck it beneath the left eye with his abalone iron, causing the shark to retreat. Tender diver John Houghton pulled the injured diver aboard without further incident. Medical examination revealed severe trauma: a crescent-shaped laceration extending 25 to 30 centimeters across the buttocks with depth penetrating 10 to 13 centimeters into muscle tissue, plus a razor-like cut to the inner left thigh measuring 8 to 10 centimeters long and 4 to 5 centimeters deep. Despite the severity, no major blood vessels or nerves were damaged. Over 150 sutures were required to close the wounds. A U.S. Coast Guard helicopter transported Worrell to Goleta Valley Community Hospital. Species identification was confirmed through dental impressions left in the wetsuit and weight belt, with shark researcher Dr. Gordon Hubbell's analysis of tooth measurements confirming a 5.5-meter great white shark.
