That depends on your definition of the word "successful." If you mean which group is more numerous and has populated more of the world, it would be the invertebrates. If you mean which has more higher intelligence, it would be vertebrates. If you mean which group is more essential to the food chain, it would be the invertebrates. If you mean which has the largest animals, it would be the vertebrates. It all depends on what you're talking about.
They are qualified as invertebrates and belong to the group of arthropods or crustaceans
Vertebrates are animals with back bones. Invertebrates don't.
Invertebrates. They are an insect.
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.
All reptiles are vertebrates.
Gorillas are vertebrates. They belong to the group of animals called mammals, all of which are vertebrates because they have a backbone or spinal column.
No, vertebrates. Vertebrates have a backbone, invertibrates do not. Anything that has a complicated skeleton definitely has a backbone.
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 ArthropodaArthropods are invertebrates
this group is called invertebrates and vertebrates :)
vertebrates and invertebrates
The group with the most species is that of the arthropods - insects, arachnids and crustaceans. But molluscs and the three groups of worms also make up a good part. Vertebrates is just another group like the arthropods for example - "invertebrates" is incredibly general. There are way more invertebrates than vertebrates.
