Cursorial

An animal can be considered cursorial if it has the ability to run fast (e.g. cheetah) or if it can keep a constant speed for a long distance (high endurance).

"Cursorial" is often used to categorize a certain locomotor mode, which is helpful for biologists who examine behaviors of different animals and the way they move in their environment.

[1][2] The most accepted definitions include that a cursorial organism could be considered adapted to long-distance running at high speeds or has the ability to accelerate quickly over short distances.

[3] There are a few mammals that have been termed "micro-cursors" that are less than 1 kg in mass and have the ability to run faster than other small animals of similar sizes.

[11] Elongation of the limbs does increase stride length, which has been suggested to be more correlated with larger home ranges and foraging patterns in ungulates.

Several species of birds are also cursorial, mainly those that have attained larger body sizes (ostrich, greater rhea, emu).

[22] Many Blattodea have very sensitive cursorial legs, that can be so specialized they run away at the puff of wind, such as the American cockroach.
