Gorilla celebrates her 55th birthday with her own cake

Jenny also enjoyed banana leaf-wrapped treats at her wooded home in the complex.

Her caretakers say that Jenny, about 210 pounds, has a few joint issues and her eyesight isn't what it used to be. But Jenny still looks good for an old ape.

Curator Todd Bowsher says 55 is a good long old age for a gorilla.

In the wild, gorillas normally would live to about 35.

Her handlers at the Dallas Zoo describe Jenny as very sweet, though a little bossy, especially when she doesn't want to go out into a more open area of her pen.
