The sharks – believed to be Spinners, between 3ft and 7ft long – were spotted by helicopter pilot Steve Irwin.

Experts said the sharks are probably migrating and heading for warmer waters, they typically swim close to the shore so that they can chase after bait-fish.

Steve spotted and filmed the sharks swimming parallel to the east coast’s idyllic white beaches between Fort Lauderdale and exclusive Jupiter Island.

In the late 80s I started investigating UFOs and crop circles and joined the CCCS (Centre for Crop Circle Studies) and a local group researching strange sightings and reports along the south coast of Dorset (UK). In the early ’90s I started my own research group called SPS (Strange Phenomena Studies), this was renamed in 2004 to Cryptoworld.
