Fun Fact(s):
One of oldest reptiles ever female named Tu’I Malila, estimated to have hatched in 1777 & died on May 16, 1996. 1 source claims Captain James Cook/1 of his crew members gave her as gift to Tongan royal family in July 1777. Other source claims Tongan king George Tupou I got her from vessel called in Ha’apai in early 1800s. Either way, she was taken to Mu’a in E part of main Tongan island & kept in compound called Malila, where she got name. In 1921, she was moved from Malila to Royal Palace by queen Salote Tupou III, where she lived until death.
