Annelida shows metmerism .
they are metameric beings (segmented body), they have anexoskeleton made of chitin and they present articulated limbs.
In biology, metamerism is 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.
No Mollusc has any segmentation.
Vertebrates belong in the phylum Chordata.
In the Kingdom Animalia, there are nine major phyla:Phylum Porifera (sponges) Phylum Cnidaria (jellyfish) Phylum Platyhelminthes (flatworms) Phylum Nematoda (roundworms)Phylum Annelida (earthworms)Phylum Mollusca (snails)Phylum Echindodermata (starfish)Phylum Arthropoda (lobsters)Phylum Chordata (humans)
Metameric segmentation is a characteristic feature of the phylum Annelida, which includes segmented worms such as earthworms and leeches. These animals have a linear series of body segments that are repeated along the length of their body.
Distinguishing characteristics of the phylum annelida are conspicuous metameric segmentation, they are triploblastic, coelomate, bilaterally symmetrical, tubular bodies (worms), they have a nervous system and some sense organs
If an organism is "metamerically segmented", it is composed of many connected parts which are very similar in structure. For example, an earthworm is metamerically segmented, because if you look at it you can see lots of little rings. Check the Wikipedia page on "Metamerism" for more information.
segmentation
Annelids is one type of worm, their long and moist body composed of many internal organs that are duplicated all times. Well, by having metameric segmentation, they can still survive if one other segment damaged or injured.
No, molluscs do not have segmentation, although there are three body regions which are not considered segmentations; a head, visceral mass and the (muscular) foot.

Annelida (segmented worms) is the phylum in kingdom Animalia that exhibit external segmentation, with visible body segments along their length. This characteristic segmentation is a defining feature of the group, allowing for greater flexibility and movement.

There are three phylums that contain worms. Platyhelminthes are the flat worms, Nematoda are the round worms, and Annelida are the segmented worms. The Bearded Fireworm is a part of the Annelida phylum because its body has segmentation.
