I would say that birds are the most successful, but mammals are right up there, too. Another way to look at it . . . mammals survived when most dinosaurs did not. Birds, on the other hand, ARE modern dinosaurs of the class Therosaura.
This is like trying to answer the old question, "Which came first, the chicken or the egg?"
Amphibians
vertebrates
No , no , Amphibia is not most successful group of land vertebrates .It is least successful .
Birds are considered one of the most successful vertebrates due to their diversity, adaptability, and ability to inhabit nearly every ecosystem on Earth. Their unique adaptations such as flight, beaks, and diverse diets have allowed them to thrive and evolve into over 10,000 species globally.
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.
Insects, easily. They account for about 75% of the entire animal kingdom, including vertebrates! ^^
vertebrates
What materials make up the endoskeletons of most vertebrates
Yes, most fish species have backbones, therefore are vertebrates.
since rats are mammals, they are most definitely vertebrates.
Five organs that are found in most vertebrates are the brain, stomach, heart, eyes and skin. Vertebrates are animals that have a spine.
Inveretbrates because it gets a better mOvementi
