Females give birth to litters of two to fourteen pups, each about 4-5 feet long at birth. Young sharks, known as juveniles, typically inhabit warmer, shallow waters close to shore, which serve as their nursery grounds.

California's "Red Triangle" is notorious for its high incidence of shark attacks. Over one-third of all great white shark attacks in the United States occur in this region. The region's moniker, the "Red Triangle," reflects its dangerous reputation, covering roughly 200 miles of coastline. It begins around Bodega Bay, extends southward to about 50 miles west of San Francisco, and concludes in the Big Sur region.

However, it's not the beachgoers and surfers that attract these formidable predators. Instead, the Red Triangle is teeming with marine mammals such as elephant seals, harbor seals, sea lions, and sea otters, which are the preferred prey for great whites. As apex predators, great white sharks play a critical role in the marine ecosystem by maintaining the balance of species below them in the food chain. They primarily feed on marine mammals, as well as fish and seabirds. Their hunting strategy involves powerful, stealthy ambush attacks, using their keen sense of smell and ability to detect electromagnetic fields to locate prey.

Despite their preference for marine mammals, great whites occasionally come into contact with humans. Contrary to the popular myth that great whites mistake surfers for seals due to poor eyesight, these sharks actually have excellent vision. Their interactions with humans are often the result of their curious nature, leading them to "taste test" unfamiliar objects, including people. Globally, great white sharks are responsible for more human attacks than any other shark species. Nonetheless, it's important to remember that shark attacks remain rare, and the overall risk to beachgoers is still minimal. Since record-keeping began, there have been only 16 fatal shark attacks in California.

For those interested in observing Great White Sharks, guided tours are available at various locations along the California coast.
