Salmon sharks can live between 20 and 30 years and reach a maximum of 4 m (12 ft) in length. They are often mistaken for Great White sharks when found on the beach, but can be easily distinguished by the presence of a secondary caudal keel and their smooth, narrow, non-serrated, teeth.
Key identifying characteristics
1. Caudal keel (small horizontal fin in front of the tail fin)
2. Secondary keel present under caudal keel
3. Secondary dorsal fin directly above secondary ventral fin
4. Some individuals have dark splotches on white underside
5. Teeth narrow and non-serrated
