About 70 short-finned pilot whales were spotted about 5 miles off the Southern California coast on Nov. 3, marking the first time local whale-watching crews have encountered the species since 2015.
According to Jessica Rodriguez, education manager for Davey's Locker and Newport Landing Whale Watching, short-finned pilot whales typically prefer warmer, deeper offshore waters, making the encounter particularly unusual.
Rodriguez said a strong El Niñocould be influencing ocean conditions and may be connected to the whales' presence near the coast, although the exact reason remains unclear.
Despite their name, short-finned pilot whales are actually members of the dolphin family. They are highly social animals that usually travel in close-knit family groups
of 15 to 50 individuals, though multiple families can gather into much larger pods.
The species is also known for its deep-diving abilities. Short-finned pilot whales primarily feed on squid and use echolocation to navigate and locate prey hundreds or even thousands of feet below the ocean's surface.
