Scuba Diver Injured by Silky Shark During Photography Work Off Palm Beach

On September 8, 1985, Morris M. Vorenberg, a marine researcher from the Rosensteil School of Marine Sciences, was conducting underwater shark photography approximately 2.5 miles off Palm Beach, Florida, in the Atlantic Ocean. Operating at a depth of 40 feet in 70 feet of water, Vorenberg and four colleagues were documenting a school of 20 to 25 silky sharks using high-intensity lights and cameras. Sea conditions were favorable, with clear visibility, 3-4 foot seas, and a water temperature of 84°F. While adjusting his photographic equipment, a single silky shark, approximately 1.8 meters (6 feet) in length, approached Vorenberg from his left rear. Attempting to prevent the shark from getting too close, Vorenberg reached down with his left hand to push the shark away. His hand made contact with the shark's snout just as the animal opened its mouth, resulting in a laceration to the palm and four small puncture wounds. The shark immediately withdrew and exhibited no further aggressive behavior. Vorenberg and his four companions ascended to the surface without incident, and no sharks followed them upward. The victim was transported by boat directly to the hospital, where he received immediate emergency treatment. Surgical repair was postponed until the following day due to excessive swelling. Vorenberg, who was wearing full scuba gear and a tethered bang stick at the time, characterized the incident as an unintentional collision rather than an aggressive attack, noting the shark showed no evidence of predatory behavior or feeding intent. The encounter was documented by the victim himself, who was also the case investigator.
