Answer. Advantage of metamerism in animals: It permits the body for specialized functions such as feeding, locomotion, and reproduction. Specialization of body regions in a metameric animal is called tagmatization .
Metamerism is beneficial to these organisms in several ways. Since each segment has its own set of muscles, each can move independently of the others. This allows for a unique type of mobility for annelids. The compartmentalization of the segments also lessens the impact of injury to the organism.
Beside this, What is the advantage of Metamerism in animals?
Advantage of metamerism in animals: It permits the body for specialized functions such as feeding, locomotion, and reproduction. Specialization of body regions in a metameric animal is called tagmatization .
Likewise, What is Tagmatization and why is it advantageous for Metameric animals?
What is tagmatization, and why is it advantageous for metameric animals? … The advantage of tagmatizations lies in the fact that each tagmata (made up of functionally similar metameres/ segments) performs a specialized function that is independent of other tagmata.
Also, What are the advantages of Metamerism?
What are the advantages of metamerism 1. Redundancy-repetition of parts means that if the organs in one segment fail, there are other segments that may still be functional 2. Reproduction-Loss of segments containing reproductive cells does not destroy the animal–example of the palolo worm of the South Pacific.
What are the evolutionary advantages of Metamerism?
Metamerism has helped in locomotion in many ways. The co-ordination of muscle contraction and the fluid filled coelomic cavity makes swimming and locomotion movement more efficient and it is more advanced over ciliary or creeping movement found in lower invertebrates.

What is Metameric segmentation in zoology?
Segmentation, also called metamerism, or metameric segmentation, in zoology, the condition of being constructed of a linear series of repeating parts, each being a metamere (body segment, or somite) and each being formed in sequence in the embryo, from anterior to posterior.
What are the advantages of having a segmented body?
Segmentation provides the means for an organism to travel and protect its sensitive organs from damage. The ability to divide functions into different portions of the body allows an organism to perform increasingly complex activities and use different segments to perform varying functions.
What are the advantages of a segmented body in worms?
The segmented body parts provide important structural functions. Segmentation can help the earthworm move. Each segment or section has muscles and bristles called setae. The bristles or setae help anchor and control the worm when moving through soil.
What is Metameric segmentation?
The repetition of organs and tissues at intervals along the body of an animal, thus dividing the body into a linear series of similar parts or segments (metameres). It is most strikingly seen in Annelida. … Metameric segmentation is thought to have arisen as an adaptation to more efficient locomotion.
What is the evolutionary advantage of having a segmented body quizlet?
What is the evolutionary advantage of having a segmented body? It allows for greater flexibility and more complex movements.
What does it mean to have a segmented body?
A segmented body is a division of an animal’s body plan, whereby the body is divided into functional units. These units form 3 sections, whether individually or together with other segments. … Arthropods, meaning animals with jointed appendages such as the dragonfly pictured above, have segmented bodies.
What are the advantages of a segmented body?
Answer and Explanation: A segmented body presents many advantages such as free movement of different body parts independently, it also allows for regeneration in certain species of organisms, and enables more advanced motor functions. Segmented bodies allow the organisms to travel and protect themselves from damage.
What is Metameric segmentation give example?
Metameric segmentation is the characteristic of Annelida and Arthropod. It is true segmentation in which external segmentation corresponds to the internal segmentation and the body is divided into a number of segments. Animals which belong to phyla Annelida and Arthropoda exhibit metameric segmentation.
What is Metamerism in animals?
In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions. In animals, metameric segments are referred to as somites or metameres.
What is Metamerism in zoology?
Segmentation, also called metamerism, or metameric segmentation, in zoology, the condition of being constructed of a linear series of repeating parts, each being a metamere (body segment, or somite) and each being formed in sequence in the embryo, from anterior to posterior.
