    Comments on Pteropus:
    i) Bats are the only mammals capable of true flight, that is, flight powered by muscular movement as distinct from gliding.
    ii) The wing is a double membrane of skin stretched between the enormously elongated bones of four fingers and extending along the body from the forelimbs to the hind limbs and from there to the tail.
    iii) The thumb is small, clawed, and free from the membrane.
    iv) The hind limbs are small and may be rotated in such a way that the knees bend backward rather than forward, as in other mammals; this is presumably an adaptation for takeoff and flight.
    v) Bats at rest hang head down, grasping a twig or crevice with their clawed feet; they take off into flight from this position.
    vi) Nearly all bats are nocturnal and many live in caves; although they see well, they rely primarily on their highly developed hearing, using echolocation (sonar) to avoid collisions and to capture insects in flight.
