# Review finds 427 cases of primates bonding with other animals 2026-08-07T08:41:49+00:00 | Health & Science | Indian Opinion Desk Corroboration: 1 independent outlet A systematic review has identified 427 documented cases of primates engaging socially with animals outside their own families, involving 88 primate species and 127 non-primate species. The findings, reported by The Times of India from a Springer study, cover wild and captive settings, with 311 cases recorded in the wild and 111 in captivity. Play and grooming were the most common behaviours, accounting for 139 and 136 cases respectively. Young primates played more often, while adult females showed more grooming and caregiving. Examples include Japanese macaques grooming and riding sika deer, gorillas cradling bushbabies and a capuchin caring for a marmoset. The review cautions that some encounters involved violence, abduction or neglect, rather than mutual care. ## Coverage - timesofindia.indiatimes.com Tags: animal behaviour, evolution, primates, scientific research, wildlife Canonical: https://indianopinion.org/review-finds-427-cases-of-primates-bonding-with-other-animals/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
