There are many reasons why the mangrove in Senbena attracts people to visit. Most of them are long-nosed monkeys, who are very selective. They are said to eat only mangrove leaves, and their habitat can not be more than 600 meters away from the sea. Finally, the old ancestors of the long-nosed monkeys decided collectively to be in this tropical mangrove in Sabah, Malaysia, and attracted them. Explorers and tourists came thousands of miles to visit.
