Cartilaginous structure attached to the tarsus and supporting the interfemoral membrane.
2nd metacarpal
Long wing bone connecting the carpus to the first phalange of the 2nd finger and supporting the wing membrane.
3rd metacarpal
Long wing bone connecting the carpus to the first phalange of the 3rd finger and supporting the wing membrane.
4th metacarpal
Long wing bone connecting the carpus to the first phalange of the 4th finger and supporting the wing membrane.
5th metacarpal
Long wing bone connecting the carpus to the first phalange of the 5th finger and supporting the wing membrane.
claw
Stiff pointy corneous structure mainly enabling the bat to attach itself to an object.
foot
Terminal end of the foot having five toes pointing toward the back and ending in powerful claws; with it, the bat hangs upside down when at rest.
tibia
Long and powerful leg bone supporting especially the interfemoral membrane.
tail
Terminal appendage of the body supporting especially the interfemoral membrane.
interfemoral membrane
Fold of smooth skin between the legs and the tail; it provides stability when the bat is in flight and capturing prey.
thumb
First digit of the wing; it is short and bears a claw.
radius
Long and powerful wing bone supporting the wing membrane.
elbow
Articulation allowing flexion and extension of the wing.
wrist
Articulation of the wing to which the digits are attached.
nose leaf
External opening of the nasal cavity located above the mouth and having a highly developed olfactory function in particular.
tragus
Protuberance of the external opening of the ear; it improves receptivity by concentrating beams of incoming sound echoes.
ear
Organ of hearing that receives echoes of the sounds the bat emits to locate obstacles and prey.
wing membrane
Smooth fold of skin stretching between the digits of the wings and extending to the feet; it is used mainly for flight and thermoregulation.
blood vessels
Channels in which blood circulates; they regulate the body’s temperature.
head
Anterior portion of the body containing the main sensory organs and the brain.
wings
Appendages of flight comprised of a cutaneous membrane supported by four very long fingers (only the thumb remains free); the bat folds its wings when resting.
