The dolphin had a badly lacerated back when she was found in John’s Pass off Madiera Beach earlier this month.
Blair Mase of the National Oceanic and Atmospheric Administration told the Tampa Bay Times says a team of biologists and veterinarians tracking the dolphin are “slightly encouraged”.
But they consider her condition to be potentially life-threatening.
Last week biologists took pictures of the dolphin that show deep propeller cuts on her back and tail.
Mase says the cuts likely go as deep as the bone.
The agency plans to track the dolphin they’ve named Babyface through the weekend before deciding whether to let her heal in the wild or be captured and rehabilitated.
