Black and White Ruffed Lemur, MadagascarThe black and white ruffed lemur is quite large for a lemur and can grow up to 4 feet tall. They are strictly diurnal and active during daylight hours only. Like most members of the family Lemuridae, they are endangered due to habitat loss and other factors. This one was living free on an island for rescued lemurs in central Madagascar.
