Drone footage captured a rare moment off Ventura County, California, when a great white shark released a cloud of white particles while swimming. Videographer Carlos Gauna, 45, said such natural behaviours are seldom seen and offer a unique glimpse into the lives of these predators.

Officials in Scarborough informed the public of a "potential shark sighting in local waters, specifically in the area off the south tip of Richmond Island, Crescent Beach State Park, Higgins Beach and Pine Point Beach" located along the Maine coast. All beaches are within a half-hour's drive of Portland.

White sharks, made famous 50 years ago in the movie “Jaws,” are not commonly seen off Maine, but have lived in the state’s waters for centuries. Sightings ticked up in recent years, and some scientists say the state’s growing population of seals could be a reason for more shark activity. White sharks feed on marine mammals such as seals.
