An unusually strong El Niño phenomenon has brought a variety of exotic marine species to California's shores, creating a notable visual display and a buzz among fishermen and marine enthusiasts. The longfin bigeye fish was spotted in California for the first time last month, and sea turtles nested on its beaches. Additionally, a venomous yellow-bellied sea snake swam ashore, while whale sharks and hammerheads have been observed cruising just off the coast. This influx of tropical species is attributed to the warm ocean water pushed farther north by El Niño. Businesses like Dana Wharf Sportfishing & Whale Watching have reported a significant increase in catches of species such as yellowfin tuna, wahoo, and dorado. Experts anticipate conditions will return to normal after El Niño passes next year, though kelp, which thrives in colder waters, may face short-term harm.
