What are the soft-bodied animals?
This include animals such as earthworms, jellyfish, tapeworms, squids and an enormous variety of animals from almost every part of the kingdom Animalia.
What is soft-bodied animals with hard external shell?
Molluscs, one of the largest groups in the animal kingdom, have soft bodies and generally have a hard shell for protection – so they are often called “shellfish”.

Is jellyfish an animal?
jellyfish, any planktonic marine member of the class Scyphozoa (phylum Cnidaria), a group of invertebrate animals composed of about 200 described species, or of the class Cubozoa (approximately 20 species).
Are arthropods soft-bodied?
The soft-bodied arthropod has primary segmentation and muscles that are intrasegmental, or within each segment. Movement of the body and its parts is relatively simple because the body wall is flexible.
Which animals are also known as soft-bodied invertebrates?
Soft-bodied animals called mollusks are the second largest group of invertebrates. Octopuses, jellyfish, sponges, and starfish are a few of the many mollusks that live in or near the water. Some mollusks, such as snails, clams, and oysters, do not have an exoskeleton.
Why molluscs are called soft-bodied animals?
The name “mollusca” signifies a soft body, since the earliest descriptions of mollusks came from observations of unshelled cuttlefish. Mollusks are predominantly a marine group of animals; however, they are known to inhabit freshwater as well as terrestrial habitats.
Is a clam a shell?
Like oysters and mussels, clams are bivalves, a kind of mollusk that's encased in a shell made of two valves, or hinging parts. And that shell comes in all different sizes.
Are invertebrates soft bodied?
Invertebrates are generally soft-bodied animals that lack a rigid internal skeleton for the attachment of muscles but often possess a hard outer skeleton (as in most mollusks, crustaceans, and insects) that serves, as well, for body protection.
Do insects have shell?
Insects have exoskeletons made of a substance called chitin. ... The animal's body then forms a new exoskeleton. The animal has no protection while the new exoskeleton is forming. Such animals as clams, oysters, mussels, and snails have a type of exoskeleton called a shell.
Are exoskeletons shells?
An exoskeleton (from Greek έξω, éxō "outer" and σκελετός, skeletós "skeleton") is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. In usage, some of the larger kinds of exoskeletons are known as "shells".
What has a shell but is not an animal?
Mollusks. Most of the seashells we know are part of a classification of animals collectively called “mollusks.” Clams, mussels and the triton or trumpet shell are just some of the invertebrates that belong to the phylum Mollusca.
