Diver bumped by porbeagle shark in Eastport
Case number: 22 |
Date: 2010-10-23 |
Location: Eastport, Maine (± 2 km from Canadian border) |
Incident type: Bumping or attempted slashing — Code: HR |
Species (Confirmed): Porbeagle shark (Lamna nasus) |
Possible cause(s): Presence of fish pens or electronic devices (Provoked) |
Result: No injury |
Status: Confirmed¹ |
Description: The victim, Scott MacNichol, from nearby New Brunswick (Canada), was diving under an empty salmon pen where he was circled and then bumped in what was potentially an attempted slashing by a porbeagle shark. The confrontation was filmed on video (see below).
Assessment: The porbeagle shark is mainly a fish eater not known to feed on or attack marine mammals. This highly unusual incident involving a human may thus have been caused in part by the nearby presence of fish in other pens, which may have stimulated the shark’s feeding behaviour. The shark may also have perceived the diver as a competitor for the same food source and attempted to ward him off. Lastly, the shark may have been further stimulated or irritated by the electrical field produced by the diver’s camera system. Note: Bump and bite attacks are characterised by the shark circling then bumping its victim before a possible slash, bite or feeding. Click here for scuba diving recommendations. |
