Anything that is not categorized in the Phylum Chordata and Subphylum Vertebrata is considered an invertebrate In short, the grasshopper is the invertebrate
The majority of chordates are found in the subphylum Vertebrata, which includes organisms with a backbone composed of vertebrae. Vertebrates such as fish, amphibians, reptiles, birds, and mammals belong to this subphylum.
The oldest subphylum is likely the subphylum Vertebrata, which includes animals with a backbone, such as fish, amphibians, reptiles, birds, and mammals. Fossil evidence suggests that vertebrates appeared around 500 million years ago during the Cambrian period.
The subphylum Vertebrata is composed of seven distinct classes of organisms, including Agnatha (jawless fish), Chondrichthyes (cartilaginous fish), Osteichthyes (bony fish), Amphibia (amphibians), Reptilia (reptiles), Aves (birds), and Mammalia (mammals).
