The common thresher shark (Alopias vulpinus) is a distinctive and rarely seen species in the waters off Monterey, California, known for its extraordinarily long, whip-like tail fin, which can be as long as its body. In Monterey, they are often found in both nearshore and offshore environments, particularly around the Monterey Submarine Canyon, where they take advantage of the abundant marine life. While not as frequently encountered as other shark species in the area, thresher sharks are sometimes observed by fishermen, divers, and researchers. They are highly migratory and prefer temperate waters, making Monterey’s cooler, nutrient-rich ecosystem a suitable habitat during certain times of the year. Conservation efforts are important for this species, as they are vulnerable to overfishing and bycatch due to their slow reproductive rates.
