Over 40 pilot whales have been stranded off Florida's gulf coast, and officials are working desperately to herd them in to deeper water. A fishing guide discovered a group of 51 whales in shallow water near Highland Beach earlier in the week. Since the discovery, 10 whales have either died or had to be euthanized. The whales need to make it at least 20 miles to reach deep waters. So far, attempts to herd the pod of whales have been unsuccessful.

It is not known how these whales ended up in such shallow waters. Typically, whales are stranded due to sickness, poor food supply, or parasites. Because pilot whales are highly social, it's possible that some of the healthy whales are staying with their ill podmates. Officials are not optimistic that the whales will make it back to safety. "It's not a good sign that they're staying so close," said Linda Friar, a spokeswoman for the park. "They're a species that like to stay together, and we're just not able to get them to move away."
