Kayla Aven, 13, of Memphis, Tenn., helps look for Bama, a 1000-pound manatee in Scipio Creek off the Apalachicola River in Florida, Friday, June 18, 2010, in order for her father, Allen Aven, a graduate student at the Dauphin Island Sea Lab, to observe her behavior. Aven is closely monitoring Bama, and Bumpy, two manatees tagged by the Dauphin Island Sea Lab, for changes in their behavior since the Deepwater Horizon oil spill.
