2 Americans attacked by a shark in the Bahamas share their ordeal

A dream vacation in the Bahamas for two young American tourists turned into a nightmare when they jumped into the sparkling blue water hand-in-hand and mere minutes later were attacked by a shark.

Rileigh Decker, 20, and Summer Layman, 24, were swimming in Bimini Bay, a popular resort area about 50 nautical miles off the coast of Florida, Friday evening when the attack unfolded, Royal Bahamas Police said in a statement Saturday.

The women are now back in Florida, sharing the harrowing ordeal from Decker's hospital bed, after both women suffered bites from what they believe was a bull shark.

“We’re just very grateful to still be here with all of our limbs,” Decker told NBC's TODAY show Tuesday.

On that fateful day, the girls had plunged into the sea off a friend’s yacht, but soon after Decker said she “felt something nudge my leg.”

“I was like, ‘Summer, what was that?’ And she was like, ‘Don’t scare me like that.’ And probably about two minutes later, we were right by the ladder. I felt my leg get tugged down, and I immediately knew I was bit by a shark,” Decker recalled.
