Food critics
Gorillas are picky feeders, spending a quarter of their day eating vegetation
Growing pains
Gorillas take around 12 years to become fully grown
Sharp smiles
Unusual for a herbivore, gorillas have large, sharp canines which they use for display and defence
Small but mighty
Newborn gorillas are born weighing around 1.5-2kg, smaller than a human baby

This helps maintain healthy and resilient zoo-based animal populations by preserving genetic diversity, supporting animal husbandry knowledge, and ensuring exceptional animal welfare, safeguarding the species for the future.
Conservation status (IUCN)
Critically Endangered
Saving the Silverbacks
With less than 300,000 Western Gorillas and only 5000 Eastern Gorillas left in the wild, all four subspecies are Endangered or Critically Endangered. The loss of habitat for mining, palm oil, agriculture, and urban expansion are pushing gorillas closer to each other and people. Living closer to people leads to higher rates of poaching for bushmeat. Civil war and unrest in the region have further decreased populations in recent decades. Their close relatedness to humans also puts them at risk of catching diseases from people, including Ebola and COVID-19. Most gorillas live in unprotected land, increasing these risks.
Protecting gorillas requires protection of their habitat, allowing to live, forage and reproduce without risk of poaching and diseases from humans.
Taronga has supported a range of programs in Africa focused on ending poaching, protecting habitat and eliminating poverty for those that live alongside gorillas. Every mobile phone recycled at Taronga further supports these efforts.
