Definition of flying squirrel in English English dictionary
Any of 43 species of squirrels from the Pteromyinae subfamily; they cannot fly, but glide from tree to tree
Any of various nocturnal squirrels of the genera Pteromys, Petaurista, Glaucomys, and related genera, having membranes along each side of the body between the forelegs and hind legs that enable it to glide between trees. Any member of two distinct groups of rodents that are able to make gliding leaps by means of parachute-like membranes connecting their forelegs and hind legs on each side. North American and Eurasian flying squirrels, in the squirrel family (Sciuridae), are slender, long-limbed forest dwellers with soft fur and large eyes. They are 3-24 in. (8-60 cm) long, excluding the often-flattened tail, and feed on nuts, fruit, other plant material, and insects. They seldom descend to the ground. They can glide 200 ft (about 60 m) or more from one tree to another. The scaly-tailed flying squirrels of Africa (family Anomaluridae) have rows of scales on the underside of their tufted tail that help them climb and cling to trees. They are similar in appearance and feeding preferences to the sciurids and are about 4-16 in. (10-40 cm) long without the tail
squirrel that can glide through the air due to winglike folds of skin between its front and hind legs
One of a group of squirrels, of the genera Pteromus and Sciuropterus, having parachute-like folds of skin extending from the fore to the hind legs, which enable them to make very long leaps
