About Mouse deer:
?    The Indian Spotted Chevrotain (Moschiola meminna) is often referred to as the Mouse Deer.
?    This diminutive animal is nocturnal in habit, making it very difficult to see one in daylight.
?    Occasionally a chevrotain may be seen late in the evening or early in the morning if it ventures out into the open like the one in this image, photographed one foggy morning near the Kabini backwaters in Nagarahole.
?    The mottled markings on their body provide them excellent camouflage, helping them to hide in their environment, especially if the animal stays immobile.
?    The Indian Spotted Chevrotain is a denizen of evergreen and deciduous forests of India and may be partial to well-watered areas.
?    Adults are mostly solitary except at the time of courtship. During the day, chevrotains stay concealed in dens that may be in hollows at the base of trees or in rocky crevices.
?    Being ruminants, they have a four-chambered stomach like other deer though it is not considered to be a true deer.
?    They also have many characters that are more pig-like. They lack antlers that most true deer sport and instead posses well developed canine teeth, which are probably used in fights.
