Eco-Economically Indispensable Borneo-Endemic Flora and Fauna: Proboscis Monkey (Nasalis larvatus), Malaysian Mahseer (Tor tambroides), Engkabang (Shorea macrophylla), Sarawak Rasbora (Rasbora sarawakensis) and Sago Palm (Metroxylon sagu)

The Borneo Island is the third-largest island and one of the greenest islands on earth. It is the natural habitat to various endemic flora and fauna such as the proboscis monkey (Nasalis larvatus), Malaysian mahseer (Tor tambroides), engkabang (Shorea macrophylla), Sarawak rasbora (Rasbora sarawakensis) and sago palm (Metroxylon sagu). In this mini review, we ventured into the current research, eco-economical aspects and potentials of each species and further provided future perspectives and recommendations to drive future research to greater heights besides supporting conservation endeavours.
