Because they both belong to the Phylum Chordata in which they are both chordates (chordates are defined as organisms that possess a structure called a notochord, at least during some part of their development).

What else can I help you with?
What level of classification do humans share with lizards?
Humans and lizards share the same level of classification as vertebrates, belonging to the Phylum Chordata.
Is hemichordata same as protochordata?
No, hemichordata and protochordata are not the same. Hemichordata is a phylum of marine deuterostome animals, while Protochordata is a subphylum of chordates that includes organisms like tunicates and lancelets. Both groups are primitive chordates but belong to different taxonomic classifications.
What is classified as the same phylum as humans?
Sea squirts are classified in the same phylum (Chordata) as humans.
Why are sharks and humans in the same phylum?
Sharks and humans are in the same phylum, Chordata, because they both have a notochord (a flexible rod that provides support) at some stage of their development. This common characteristic places them in the same phylum, alongside other animals that possess a notochord at some point in their life cycle.
Two species belonging to the same class must also belong to the same?
Phylum. Organisms in the same class belong to the same phylum, which is a higher taxonomic rank that groups organisms based on shared characteristics.
Do tunicates and lanceletes have back bones?
No. They are both chordates, which means during embryonic development they have a notochord, the same as vertebrates. This does not persist in tunicates, but it does in lancelets (adults still have a notochord). Neither tunicates or lancelets have a backbone.
Is the phylum the same for all vertebrates?
Yes. All vertebrates are in the Phylum Chordata.
Classes with similar characteristics are grouped into the same?
Phylum.
What level of classification do humans share with lizards?
Humans and lizards share the same level of classification as vertebrates, belonging to the Phylum Chordata.
Amphibians are grouped in what kingdom?
Amphibians are part of the kingdom Animal. Same worms and humans. To narrow it down, they are part of the Phylum Chordate.
Is hemichordata same as protochordata?
No, hemichordata and protochordata are not the same. Hemichordata is a phylum of marine deuterostome animals, while Protochordata is a subphylum of chordates that includes organisms like tunicates and lancelets. Both groups are primitive chordates but belong to different taxonomic classifications.
How closely related is a lobster to a spider?
About as closely as we are to frogs. Crustacea and Chelicerata (arachnids) are different classes in the same phylum (Arthropoda), just like mammals and amphibians are different classes in the phylum Chordata (vertebrates).
What is classified as the same phylum as humans?
Sea squirts are classified in the same phylum (Chordata) as humans.
What phylum is sharks in?
Sharks belong to the phylum Chordata, which is the same phylum that includes other vertebrates such as mammals, birds, reptiles, and amphibians. Within the phylum Chordata, sharks specifically belong to the class Chondrichthyes, which includes cartilaginous fish like sharks, skates, and rays.
Why are sharks and humans in the same phylum?
Sharks and humans are in the same phylum, Chordata, because they both have a notochord (a flexible rod that provides support) at some stage of their development. This common characteristic places them in the same phylum, alongside other animals that possess a notochord at some point in their life cycle.
Are reptiles the same as vertebrates?
No, they are not the same, but all reptiles are vertebrates. Not all vertebrates are reptiles, they could be fish, mammals or birds.
Is phylum Cnidaria same as phylum coelenterata?
Yes. Coelenterates are the same as Cnidaria.
