It integrates the biomechanics of animal movement with the physiology of animal energetics and the neural control of locomotion.
Locomotion Animals have evolved an amazing variety of ways to get around. There are animals with no legs; animals with one appendage that serves as a "leg" snails, clams ; animals with two, four, six, or eight legs; animals with dozens of legs; even animals with hundreds of legs.
There are animals that move constantly, and animals that stay in one place for their entire adult life. There are animals that swim purposefully and animals that drift wherever the currents take them. Animals slither, crawl, flap, glide, and swim.
Some animals spend their entire life underground, whereas others spend almost their entire life in the air. All of these are different modes of animal locomotion. Locomotion is not the same as movement. All animals move, but not all animals locomote.
In ethologyor the study of animal behavior, locomotion is defined as movement that results in progression from one place to another. Animals that spend all or nearly all their entire adult life in one place are called sessile. Animals that move around are called motile.
Typically, the animal uses the same mode of locomotion for all these functions, but there are exceptions. For example, a squid normally swims forward or backward by undulating rhythmically waving finlike flaps on the sides of its body.
However, when startled, the squid expels water through a nozzle and jets backward.
Shrimp have a similar behavior. They normally swim using modified appendages called swimerettes. When avoiding a predator, they contract their powerful tail muscles and rapidly move backward through the water. Even some normally sessile animals use crude forms of locomotion to escape predators.
Scallops can clap their shells together to produce a sort of jet propulsion. Some cnidarians such as sea anemones can break free from their attachment point and then use an undulating motion to swim away from a slow-moving predator.
Principles of Locomotion Locomotion can be passive or active. Each has its advantages and disadvantages. Passive locomotion is the simplest form of animal locomotion.
This behavior is exhibited by jellyfish and a few other animals. In this form of locomotion, the environment provides the transportation. The advantage is that no muscular effort is required.
The disadvantage of this type of locomotion is that the animal is at the whim of wind and wave. It goes where the current takes it. A somewhat different form of passive locomotion is exhibited by the remora the name for various species of fish in the family Echeneidae.
Remora attach themselves harmlessly to a larger fish or sea turtle and thus go wherever the larger animal goes. However, remora are perfectly capable of swimming on their own.
Most animals exhibit active locomotion at some stage of their life cycle.Animal Locomotion offers a fundamental understanding of animal movement through a broad comparative and integrative approach, including basic mathematics and physics, examination of new and enduring literature, consideration of classic and cutting-edge methods, and a strong emphasis on the core concepts that consistently ground the dizzying Author: Andrew Biewener.

LOCOMOTION IN ANIMALS. Locomotion is an important process for animals. Animals have to move from one place to another for many reasons.
They can’t stay in one place in order to support their living. Hence, certain body movements are observed in every organism but the means vary according to their body structure.
Gait of few animals are as.

Ethology is the study of animal behavior. Locomotion refers to the movement that causes a progression from one place to another. There are several different types of . Walking & Running. Walking is a terrestrial locomotion in which at least one leg is always in contact with the ground.
The speed of walking is limited by the lack of an aerial or leaping phase in which the animal propels itself through the air.
Biology Movement and Locomotion in Animals. Top. Movement and Types of Locomotion. The act of changing place or position by the entire body or by one or more of its parts is called movement. Movement is one of the characteristic features of living organisms.
