Lilly, a western lowland gorilla born at the theme park last year, is very small. She weighs just 10 pounds, less than half of what a gorilla her age should weigh.
Disney's Animal Programs team hasn't determined the source of her underdevelopment. There's no sign of another case like hers, so team members are giving Lilly the kind of occupational therapy typically reserved for human children who are developmentally challenged.
It appears that they've done a battery of tests on her, and still can't find anything. Let's hope the physical therapy works.
