GALAGO, the name of the long-tailed African lemur-like Primates (q.v.) ; classed with the lorises and pottos in the Lorissiformes. They are characterized by the great elongation of the upper portion of the feet (tarsus) and the power of folding the large ears. They pass the day in sleep, but are active at night, feeding on fruits, insects and small birds. When they descend to the ground they sit upright, and move about by jumping with their hindlegs like jerboas. They are pretty little animals, varying from the size of a small cat to less than that of a rat, with large eyes and ears, soft woolly fur, and long tails. There are several species, of which G. crassicaudatus from Mozambique is the largest.
