The UNIMAS expedition team defined the animal and plant species collected from 1,500 m to 1,800 m range above sea level as species originating from the Mount Murud; because specimens collected below this level can originate from the mountain surroundings. Mjöberg noted in 1925 that nine species of birds that were previously known as originated from Mount Kinabalu are also found at Mount Murud. This is supported by another evidence that 77% of Pteridophyte and 75% of orchids are common in both mountains. However, despite the close proximity of Mount Murud with Mount Mulu (65 km WSW of Mount Murud), both mountains have different summit flora. As of 1995, a total of 35 pteridophytes, 7 gymnosperms, 96 monocotyledons, and 207 dicotyledons were listed as summit flora of Mount Murud. The tropical pitcher plant species Nepenthes murudensis is named after the mountain and is thought to be endemic to its summit area. Also Murud black slender toad Ansonia vidua is only known from this mountain.
