Marine scientists at California State University have recently made an exciting discovery about juvenile great white sharks. They have found that these young sharks prefer warm, shallow waters near the shore, particularly within one kilometer from the coast.
This new study sheds light on the habitat preferences of juvenile great white sharks. Understanding these preferences is crucial for both shark conservation and public safety, especially as ocean temperatures continue to rise.
The researchers observed a group of baby great white sharks, also known as pups, congregating near Padaro Beach in Santa Barbara. These young sharks are left to thrive in the shallows without adult supervision, forming a unique opportunity for scientists to study them up close.
Over the course of 2020 to 2021, the research team tagged 22 juvenile white sharks with sensor-transmitters to track their movements and behavior. They found that the sharks adjust their vertical position to maintain a specific temperature range between 16 and 22 °C, with optimal growth occurring between 20 and 22 °C.
The study also revealed that juvenile white sharks occupy much shallower waters than adult great whites, who are rarely seen in nursery areas. The sharks’ movement patterns are influenced by three-dimensional temperature variations, with deeper waters cooling causing them to move closer to the surface.
While temperature plays a crucial role in attracting juvenile white sharks to these nursery areas, there are likely other factors at play. The researchers suggest that the sharks may be using specific areas within the aggregation site to increase their foraging success.
Future research will explore individual behaviors and relationships among juvenile white sharks to further enhance our understanding of their habitat preferences. These findings not only aid in conservation efforts but also help minimize human-shark interactions, ultimately ensuring the safety of both sharks and beachgoers.
