OKALOOSA ISLAND, Fla. -

Biologists are warning boaters in northwest Florida to avoid dolphins after two babies were struck and killed by a boat propeller just days apart.

The Northwest Florida Daily News reports the first dolphin washed up near Gulf Breeze last week after being hit by a boat.

The second was found Monday west of Pensacola with numerous deep cuts.

Marine biologist Steve Shippee with the Emerald Coast Wildlife Refuge performed a necropsy on the second dolphin that was struck by a fast-moving boat.

Shippee says these two dolphins are the first propeller victims he's seen. He warns boaters against getting too close to dolphins or trying to pet or feed them.
