Witnesses described one seal being attacked just offshore and another seal coming ashore. Carrie Drayton recorded the encounter. The source describes two seals but does not identify their species; the shark's identification was subsequently assessed by Gregory Skomal.
The observer reported one grey seal at 11:45 a.m. during a Dolphin Fleet whale-watch trip from Provincetown. The account places the trip around the southeastern corner of Stellwagen Bank.
A dead grey seal with a visible wound was discovered on the beach. Andrew Jacobs investigated it the next day; New England Aquarium scientist John Chisholm assessed photographs and found the wound consistent with a white-shark bite.
