Coastal waters can be important feeding grounds for white sharks, particularly areas with high densities of seals and sea lions. In addition, female white sharks also visit coastal waters to give birth to their young. Baby and juvenile white sharks have been found to use shallow open beach habitats and bays as nurseries. So, what does a white shark nursery look like? Probably like your favorite beach. And, why are they there? Probably for the same reasons you are; it’s safe in shallow waters, there is plenty of easy-to-obtain food (not to worry – that doesn’t include you), and it’s warm! Just like any summer beachgoer, baby white sharks don’t like the cold, so they quickly migrate to warmer waters, following the coastline when the temperature drops. We’ve learned all this using a variety of new technology such as acoustic and satellite transmitters, autonomous underwater and aerial vehicles (spybots), and underwater camera (selfie) stations. We’ve even learned about how El Niño can change their migration behavior and how that effects public perception of sharks. Come learn what we think makes for a good white shark nursery and where we might predict the next ones to pop up.
