The first land animals belong to which group A arthropods B echinoderms C mollusks D vertebrates?
mice and that is all i can think of.sorry........ ------------------------------------------------------ Mice, rats, and other vertebrates- including fish, mammals, amphibians, reptiles, birds, primates, rodents and marsupials- all have spines. There are many invertebrate animals (spineless) including protozoa, annelids, echinoderms, mollusks and arthropods. -Shiloh
No, they are not. Vertebrates have vertebra, which are the bones in the spinal column. Arthropods are a group of animals that have no backbone but what's called an exoskeleton. a 'skeleton' outside the body like a shell. No they are invertebrates under the group Arthropoda Arthropods are invertebrates
All animals belong in the animal kingdom. Otherwise, they would not be classified as animals. Animals themselves belong to the kingdom Eukarya, which is comprised of all multicellular life. The other two are Bacteria and Archea. The animal kingdom is made up of two groups: vertebrates and invertebrates. Some vertebrates are: mammals, reptiles, amphibians, birds, and fishes. Some invertebrates are: molluscs, worms, arthropods, coelenterates, and echinoderms.
Animals are divided into two groups, vertebrates and invertebrates. Vertebrates are animals with a backbone and invertebrates are animals without a backbone. In the invertebrates group there are mollusks, Insects, crustaceans and arachnids. Spiders are part of the arachnid group along with scorpions.
Starfish are not mollusks. Starfish are classified as echinoderms, which is a phylum of marine animals that are known for their symmetry as adults. Other animals in this phylum are sand dollars and sea urchins. Sea-stars, or starfish, belong to the class Asteroidea. Like mollusks, however, starfish can be found in the intertidal zone of the ocean, where mollusks are commonly found.
There are several different groups in the hierarchy. Animals is the kingdom that all animals are a part of. From there they are categorized by phylum, class, order, family, genus, and species. Some are: 1. amphibians 2. annelids 3. arthropods 4. birds 5. echinoderms 6. fish 7. mammals 8. mollusks 9. reptiles Those are just some of the terms!
Arthropods are only one group of invertebrate animals. There are many other invertebrates in the world. Some examples would include single-celled animals, worms, jellyfish, gastropods like slugs and snails, and echinoderms like starfish and sand dollars. Most animals in the world are, however, in the arthropod category. WikiAnswers
Echinoderms are animals that are spiny skinned like:starfish, sea cucumbers, sea urchins, sand dollars, and brittle stars. Mollusks are animals with very soft bodies, like cephalopods: squid, octopi, cuttlefish, gastropods: snails and slugs, and bivalves: clams, oyster, mussels, scallops, cockles. ~7th grader
