Centipedes have one pair of legs per body segment, with typically around 50 legs, but some species have over 200. The terrestrial animals with the most legs are the millipedes. They have two pairs of legs per body segment, with common species having between 80 and 400 legs overall – with the rare species Illacme plenipes having up to 750 legs.
The definition of orthograde posture can easily be derived from its roots “ortho-” meaning “upright” and “-grade” meaning “ascent.” This was true for the early Hominidae , whose transition to upright walking took place approximately six to seven million years ago evident in Orrorin tugenensis .

Animal Locomotion: An Electro-photographic Investigation of Consecutive Phases of Animal Movements is a series of scientific photographs by Eadweard Muybridge made in 1884 and 1885 at the University of Pennsylvania, to study motion in animals (including humans).
Colugos (/ k ə ˈ l uː ɡ oʊ / [2] [3]), flying lemurs, or cobegos (/ k ə ˈ b iː ɡ oʊ / [4]), are arboreal gliding euarchontogliran mammals that are native to Southeast Asia. Their closest evolutionary relatives are primates .
The smallest flying vertebrates are the bee hummingbird and the bumblebee bat, both of which may weigh less than 2 grams (0.071 oz). They are thought to represent the lower size limit for endotherm flight. [citation needed] The smallest flying invertebrate is a fairyfly wasp species, Kikiki huna, at 0.15 mm (0.0059 in) (150 μm). [23] Fastest.
By manipulating the alula structure to create a gap between it and the rest of the wing, a bird can avoid stalling when flying at low speeds or when landing. Feathers on the alular digit are not generally considered to be flight feathers in the strict sense; though they are asymmetrical, they lack the length and stiffness of most true flight ...
In terrestrial vertebrates, digitigrade (/ ˈ d ɪ dʒ ɪ t ɪ ˌ ɡ r eɪ d /) [1] locomotion is walking or running on the toes (from the Latin digitus, 'finger', and gradior, 'walk').A digitigrade animal is one that stands or walks with its toes (phalanges) on the ground, and the rest of its foot lifted.
In spite of the differences in leg number shown in terrestrial vertebrates, according to the inverted pendulum model of walking and spring-mass model of running, "walks" and "runs" are seen in animals with 2, 4, 6, or more legs. The term "gait" has even been applied to flying and swimming organisms that produce distinct patterns of wake vortices.
