Try looking up sea squirts (Tunicata), acorn worms (Enteropneusta) and Pterobranchia. Oh, and Branchiostoma of course, the lancelet. And in some ways hagfish aren´t considered real vertebrates either.
The octopus is not a member of phylum Chordata, so it is not a chordate.
The Phylum is Chordata, which are vertebrate animals
It's 'Chordata'
Chordata.
chordata
Cats are mammals.
Birds belong to Chordata
Yes. All animals which have a spine, or backbone, are classified in the phylum Chordata. There are three subphylums in Chordata: Urochordata (tunicates), Cephalachordata (lancelets), and Vertebrata (vertebrates). Dolphins belong to the phylum Chordata because they are vertebrates.
Birds belong to the phylum Chordata, specifically the subphylum Vertebrata. This means that birds are vertebrate animals with a backbone.
No, the phylum Chordata includes both vertebrate and invertebrate animals. Vertebrates are a subphylum within Chordata and have a backbone or spinal column, whereas invertebrate chordates, like tunicates and lancelets, lack a backbone.
None , as vertebrates are part of phyllum Chordata .
A speckled flying fox is most defiantly a vertebrate. All mammals are vertebrates being a part of the phylum chordata.
