Experts are warning that great white sharks have abandoned a nursery between Del Mar and Torrey Pines in San Diego, California, which was active for four years and had seen no great whites in this area for about a year. The nursery, which had been active for several summers, has apparently fallen out of favor with juvenile great whites. Chris Lowe, director of Cal State Long Beach’s Shark Lab, believes that these sharks depleted their favorite prey and moved on to coastal waters further north with a more plentiful food supply. However, an unusually strong El Niño could bring different species north from Mexico, potentially including tiger, bull and hammerhead sharks. While this could cause a "sharky summer" in Orange and Los Angeles counties this year, it is expected to be a rare sighting in 2026. Researchers are continuing to study the differences between juvenile and adult sharks' diets and their preferred meal sites.
