This video was filmed a few days after Momoka left Ueno Zoo. This episode is a continuation of the previous one. In this episode, you will see how Riki is steadily climbing the ladder to becoming a silverback. Haoko seems to get away from his persistent son by the end of the video. Enjoy!

Ueno Zoo released Toto's pathological exam result on October 19, 2025.

I went to see the troop on October 20, 2025, and Toto seems to be doing well with the troop. She was being fed directly by the keeper on several occasions during my visit.

About Western Lowland Gorilla
Gorilla gorilla gorilla
Habitat: The most widespread gorilla subspecies, it can be found across more than 700,000 km² of Central and West Africa.
Lifespan: 35 yrs in the wild (up to 60 yrs in captivity)
IUCN Red List: Critically Endangered
It is the smallest of the four gorilla subspecies, which also include the Cross River gorillas, Grauer’s gorillas, and mountain gorillas. It has shorter black-brown hair, longer arms, and a more prominent ridge along its brow. The adult males, called silverbacks, have silvery-grey hair on their backs and thighs. Their heads are large and pointed, with a sagittal crest forming the back of the top of the head. Its population has been decreasing due to poaching and disease. The estimated population in 2013 was almost 362,000 individuals (IUCNredlist.org). Fewer than 150,000 western lowland gorillas remain in the wild (gorillas.org).
