Biologists in Southwest Florida are watching a dolphin tangled in fishing line and suffering from a chronic skin disease. The mammal was last seen with fishing line wrapped around the top of its dorsal fin and the outer edge of its tail. The biologists say the dolphin’s life is not threatened now and they’re monitoring in case it becomes further entangled of its health condition declines. The dolphin is often spotted in canals in Port Charlotte and Punta Gorda.
