"Apes are one of the most studied species in the world. If we can still find new species in this category after 200 years of biological research, does this mean that we need to find more new information about other species, which we ignore? " Environmental protection scientist Eric megard said.

Long tail dwarf lemur

Another lovely arboreal animal, the long-tailed dwarf lemur, is smaller than a squirrel. It is the only known primate that hibernates for a long time. In order to prepare for seven months' sleep, these animals will gobble up fruits and flowers and store 40% of their body fat on their tails.

Vannunu mouse

The local people in Solomon Islands have been talking about a kind of coconut-eating Wannu mouse, which is nearly 2 kg long, but no scientists have ever confirmed its existence. Until 20 17, a big mouse fell from a tree cut down by a lumberjack to a park ranger.

"This is the first mouse found in Solomon in 80 years. It's not that people haven't tried it-it's just hard to find it. " Ravelli, the first mammalian scientist to identify the species through DNA analysis, said.

Because of the development of logging industry, scientists believe that this kind of mouse is on the verge of extinction. The mouse that Lavery found in the fallen tree soon died. "For this mouse, if we don't find it now, we may never find it." He said. "It was found in one of the remaining uncultivated forest areas."
