Buttons (click for field notes) 

Buttons is a male twin manatee who was rescued the day after he was born after being hit by a boat.  The impact collapsed one of his lungs. Unable to dive, he couldn't nurse from his mother.  He was rescued from the Keys in September of 2001 and taken to the Miami Seaquarium for treatment.  After many months of care, his lung is fully functional and he can dive and eat normally.  He was released in the Miami area with Douglas on March 2nd. 

Below are some pictures of Buttons from Miami Seaquarium:
