The Dorsal Fin

Boston’s WHDH reports that swimmers have been warned to stay at least 300′ away from seal colonies. The large seal population in the area is believed to be responsible for the increase in white shark sightings over recent years, as the seals are a natural prey item for the shark.

The warning comes after multiple credible white shark sightings were reported in the area over the past week, as well as reports of seal carcass sightings.

According the AP, three more great white sharks were tagged yesterday (09/08/09) off of Monomoy Island near Chatham, Massachusetts. This brings the total number of white sharks tagged to five, in the past week (two great white sharks were tagged in the area on Saturday). Several Chatham beaches continued to remain closed due to the presence of the great white sharks in the area.

CBS news also reported on this story, but they apparently could not resist the temptation to play up the "Jaws" angle, as seen in the video segment below.

From a shark research standpoint, the tagging of five white sharks in the Atlantic is exciting news. Hopefully, the data acquired as a result of the taggings will lead to more insight into migratory behaviors of Atlantic-bound great white sharks.
