Overview
The porbeagle shark (Lamna nasus) is a member of the Lamnidae family, which also includes the great white shark. They have a streamlined, torpedo-shaped body with a pointed snout and a large, crescent-shaped tail. Their coloration is typically dark gray to blue on the dorsal side and white on the ventral side. Porbeagles are distinguished from other similar species, such as the mako shark, by their shorter, more rounded snout and their lack of a prominent keel on the underside of their caudal peduncle.

Migratory Patterns
Porbeagle sharks exhibit seasonal migratory patterns. They typically move northward in the spring and summer, and southward in the fall and winter. In the western North Atlantic, they migrate from waters off New England and Nova Scotia to areas around the Gulf of Maine and Georges Bank. Some individuals may travel as far south as New Jersey and North Carolina in winter. In the eastern North Atlantic, they move between the waters off Norway and the British Isles to the Bay of Biscay and occasionally the Mediterranean Sea. Southern Hemisphere populations show similar patterns, moving between temperate and subantarctic waters off New Zealand, Chile, and Argentina.
