A chilling drone video shows a hammerhead shark circling a seemingly oblivious swimmer off a Miami beach. The video was posted to Instagram by drone operator and photographer Jason McIntosh. The Miami Herald reports that the close encounter was captured off South Beach on Sunday. McIntosh captioned the video, "Hammer Time," and used MC Hammer's famous song "U Can't Touch This" as the soundtrack. The video has been viewed more than 29,000 times since it was posted last week.

A stunning drone-shot video shows a great white shark swimming off a Southern California beach. The drone footage was shot by Tyler Martindale, reports KEYT News Channel 3. Martindale says that the huge predator was about 656 feet south of Santa Claus Beach in Carpinteria, Santa Barbara County. The video, which was shot on Saturday morning, clearly shows the shark swimming back and forth. Martindale said that the shark was about 10 feet long. While the great white was far away, it was still close enough to swim closer to the shore, according to Martindale.
