What significant historical southern limit did the Atlantic walrus range once reach off the coast of Nova Scotia?
Answer
Sable Island
Historically, the Atlantic walrus subspecies possessed a much broader distribution than is currently observed, pushing significantly further south than their modern, more segmented Arctic range. Specifically, evidence points to colonies flourishing historically as far south as Sable Island, which is an island located off the coast of Nova Scotia, Canada. This historical southward extension also included the area around the Greater Gulf of St. Lawrence region, demonstrating a previous ability to utilize more temperate, southerly feeding grounds compared to today's restricted Arctic habitat.
