He was smuggled from the wild to Isreal as part of the pet trade, but was seized by officials. Hananya along with other young chimps Tikko, Semach and Gypsy (who was born in captivity), were brought to Monkey World on 28th August 1996 where they were put into the nursery along with three captive born chimpanzee siblings named Bob, Arfur and Jess to be cared for by Sally. On 29th September, they were joined by another young chimpanzee named Simon, who was rescued from Spain. In 1998, they were joined by Trudy, whom Hananya and Semach treated like a younger sister and would protect her from their playmates' rough play.
That same year, Monkey World's staff made a new chimpanzee group out of Sally's group along with several adult chimpanzees named Charlie (who served as dominant male), Pacito, Mojo, Peggy and Mona (the latter three were previously members of Chico's Group until his death). Later that year, Bob died from a stomach infection and shortly afterwards, Sally became ill. Believing that Sally may have caught the same illness that killed Bob, Hananya and his playmates were brielfy separated from the adult members of the group and returned to their nursery enclosure to prevrnt them from becoming ill too. In 1999, Charlie (who had mental scars due to his earlier life as a photographer's prop) kept lashing out at the other members of the group, resulting in him and Pacito being moved into the Bachelor Group (which Mojo joined a short time before) whilst Sally returned to the nursery to care for younger chimps. Hananya, his playmates along with Mona and Peggy became members of Rodney's new group. During this time, Hananya began spending time with Jess (who had recently entered puberty), much to the dismay of Arfur, who had been raised with Jess and had a close bond with her.
Eventually, Hananya became Rodney's second-in-command. In 2004, Hananya's loyalty to Rodney faded and he into a fight with him. The other male chimps in the group (who had grown up with Hananya) took Hananya's side and attacked Rodney, but stopped after realising that they had hurt Rodney. Afterwards, Rodney was taken from the enclosure to be tended to, but died during the night from a heart attack.
Following Rodney's death, the group looked to Hananya as their new leader, but he struggled to control the group for the first few years as he found it difficult to act superior to the chimps that he had grown up with, but eventually settled into the role. He also took Tikko as his second-in-command.
In 2005, Hananya became a father after having a son with Jess named Rodders. However, Jess rejected Rodders, who was then hand reared and now lives in Bryan's Group.
In 2008, two young chimps named Ben (Rodney and Peggy's son) and Pip (Rodney and Cherri's daughter) moved into Hananya's Group from the nursery group. When meeting Hananya, Pip acted submissive to him and was accepted by him. However, Hananya felt threatened by Ben and attacked him, despite the younger chimp showing no aggression towards him. Following this, the staff decided to remove the tips of Hananya's canine teeth to stop him hurting other members of the group. Hananya and Ben where kept separate from each other until Ben moved to the Bachelor Group in 2009 following Pip's death.
In 2013, Hananya had two daughters with Cherri named Thelma and Louise. Sadly, Louise died shortly after her birth due to a hole in her heart.
Currently, Hananya still leads his group with Simon as his second-in-command, following Tikko's death in 2016.
