The Swell Shark can be ⁣found in the eastern Pacific Ocean, predominantly along the coastlines of North America and South America. ​These ⁣sharks do not exhibit migration patterns.


They prefer rocky, kelp-filled ⁣waters ‌and are usually found ⁢at a depth ⁢between 2 to ⁣450 meters. They withstand a varied temperature range, adapting to anything between​ very cold to warmer ​coastal waters.

When and ‍Where to See

Swell Sharks come out at ​night to hunt and during the day they⁣ hide ⁤in caves or crevices. Unlike ​other shark species, they exhibit⁣ no seasonal patterns.

Best Fishing Locations

Top places ⁤to ​find⁤ Swell Sharks include:
– Santa Catalina⁣ Island, California
– Baja California, Mexico
-⁢ Chilean coastline

If you’re ‌after Swell Sharks, ‍look in crevices, over ⁢rocky reefs, and under kelp ​beds, particularly at night when they are most active.
