Overview

The porbeagle is a cold-water mackerel shark with the dense, streamlined look typical of the lamnid family. It is a strong swimmer of temperate northern waters rather than a bottom shark, and its clean crescent tail makes it easy to separate from softer-bodied coastal species.

In this guide it is recorded from the North Atlantic, including European waters and the northwest Atlantic. Recorded maximum length: 3.5 m.

In the field, the clean lamnid outline, cool-water Atlantic setting, and firm crescent tail are the quickest cues.
