Former Answer by some dummy: "The most diverse group is insects, which belong to the group ARTHROPODA*.*Arthropoda-Largest and most diverse animal phylum, mostly insects."This answer is completely wrong based on the question.Arthropods are invertebrates! They are the most numerous INvertebrates.The most diverse vertebrates are BONY FISH.
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.
No. Most fish are vertebrates but the blobfish is special. It does not have any bones therefore it is a invertebrate.
fish is a type of animal. Same with birds.
vertebrates
The first and most basic distinction is to separate them into mammals, birds, reptiles and amphibians. But, every species is different and in a species there can be subspecies with their own differences. So, there are as many differences as there are species.
