which invertebrate phylum contains the sub phylum vertebrata
PLEASE HELLLLLLLPPPPPPPPPP
Thankyou in advance1111!!!!!!!!!!
:(:(:(:(:(:(
please anybody
Chordata contains the subphylum Tunicata, Cephalochordata, and Vertebrata.
The phylum that contains the subphylum Vertebrata is Chordata. To determine this, we need to understand the hierarchical classification of taxa.
1. Taxonomic Hierarchy: In biology, organisms are classified using a hierarchical system called taxonomy. The highest level of this hierarchy is the domain, followed by the kingdom, phylum, class, order, family, genus, and species.
2. Invertebrates: Invertebrates are animals that do not have a vertebral column or backbone. They make up the vast majority of animal species. Invertebrates belong to several phyla, including Porifera (sponges), Cnidaria (jellyfish, corals), Arthropoda (insects, spiders, crustaceans), Mollusca (snails, squids), and many more.
3. Vertebrates: Vertebrates, on the other hand, are animals that possess a backbone or vertebral column. They belong to the subphylum Vertebrata. Vertebrates include fish, amphibians, reptiles, birds, and mammals.
4. Phylum Chordata: The phylum Chordata is a major phylum that includes both vertebrates (subphylum Vertebrata) and some invertebrates. Chordates are characterized by the presence of a notochord, a dorsal hollow nerve cord, and pharyngeal slits. This phylum encompasses a wide variety of animals, from simple sea squirts (invertebrate chordates) to complex mammals.
So, to answer your question, the invertebrate phylum that contains the subphylum Vertebrata is Chordata.
