A young dolphin wandered off its usual path and ended up in a creek in Clearwater, Florida. Biologists with Clearwater Marine Aquarium had been monitoring the animal since Jan. 1. It appeared reluctant to return to open waters via a small opening under a bridge. "Since monitoring began, the dolphin had not left the creek," the aquarium said last week. "This posed potential long-term problems for the animal, such as isolation from other dolphins and an increased risk of harassment and human interactions."
