"It has also been observed that, when threatened, the Java mouse-deer will beat its hooves quickly against the ground, reaching speeds of up to 7 beats per second, creating a “drum roll” sound."
"One of the main predators which the Java mouse-deer face is humans. Through the destruction of their habitat, as well as from hunting and trapping the mouse-deer for food, their pelts, and for pets, humans have considerably reduced the Java mouse-deer population. Mouse-deer are particularly vulnerable to being hunted by humans at night because of their tendency to freeze when illuminated by having a spotlight shone on them."
"Historically, the mouse-deer has featured prominently in Malay and Indonesian folklore, where it is considered a wise creature. This character, Sang Kancil (pronounced “Kahn-cheel”), is a diminutive but wise mouse-deer. Sang Kancil is a tiny and cunning hero who, through his intelligence, is able to prevail over his larger tyrants and foes."
