Arboreal locomotion is the locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally (scansorial), but others are exclusively arboreal.
Legged locomotion is the dominant form of terrestrial locomotion, the movement on land. The motion of limbs is quantified by the kinematics of the limb itself (intralimb kinematics) and the coordination between limbs (interlimb kinematics). [1] [2] Figure 1. Classifying stance and swing transitions of the front right (red) and left (blue) legs ...
Adaptations for cursorial locomotion in terrestrial vertebrates include: Increased stride length by: Increased limb bone length; Adoption of digitigrade or unguligrade stance; Loss of clavicle in mammals, which allows the scapula to move forwards and backwards with the limb and thereby increase stride length. Increased spinal flexion during ...

In addition to animal locomotion, most animals are motile, though some are vagile, described as having passive locomotion. Many bacteria and other microorganisms , including even some viruses , [ 9 ] and multicellular organisms are motile; some mechanisms of fluid flow in multicellular organs and tissue are also considered instances of motility ...

Scansoriopterygidae (meaning "climbing wings") is an extinct family of climbing and gliding maniraptoran dinosaurs.Scansoriopterygids are known from five well-preserved fossils, representing four species, unearthed in the Tiaojishan Formation fossil beds (dating to the mid-late Jurassic Period) of Liaoning and Hebei, China.
Rectilinear locomotion relies upon two opposing muscles, the costocutaneous inferior and superior, which are present on every rib and connect the ribs to the skin. [5] [6] Although it was originally believed that the ribs moved in a "walking" pattern during rectilinear movement, studies have shown that the ribs themselves do not move, only the muscles and the skin move to produce forward ...
