In the first two days of September, there were 22 confirmed great white shark sightings off the outer coast of Cape Cod, the arm-shaped Massachusetts peninsula that has become the epicenter of great white shark activity in New England. In the past decade, a glimpse of a shark off the vacation hotspot’s sandy shores went from a newsworthy event to an everyday occurrence during beach season. The resurgence of great whites in New England in recent years is attributed to successful conservation measures. A similar process could be unfolding in Maine. One reason why Maine may never see sharks in large congregations is the aggregation of seals in Maine and Massachusetts is vastly different. The coast of Cape Cod has massive seal haul outs.
