Gorilla keeper Glynn Hennessy said: "Baby gorilla Gernot has quickly become the centre of attention at ZSL London Zoo's Gorilla Kingdom, but one-year-old Alika has embraced her new role of the doting big sister.
"Western lowland gorillas live in troops and learn how to act from observing each other's behaviours and manners and here we can see Alika demonstrating some of the nurturing skills she's learned from the adults."
