What kinds of animals are in the chordata phyla?
Animals with spinal cords (ex. humans, dogs and cats, whales, snakes, etc.).
All phyla except for one (Chordata) include only invertebrates, so 8 phyla include only invertebrates. The phylum Chordata is made up of the subphylum Vertebrata so therefore Chordata also has some species in it that are invertebrates. Humans are included in the phylum Chordata as well as the subphylum Vertebrata.
Chordata is a phylum, vertabrate (vertabrata) is a sub-phylum. Although this is not well-known, the phylum chordata contains some (very few) invertabrates (animals without a backbone) such as sea squirts. So the phylum chordata is futher classified into 2 sub-phyla, vertabrata (vertabrates) and invertabrata (invertabrates).
My reference is a book which is "A Cyber Science". It says here that there are so many phyla. Example of phyla: Phylum Platyhelminthes Phylum Nemathelminthes Phylum Annelida Phylum Arthropoda Phylum Porifera Phylum Chordata Phylum Nematoda Phylum Coelenterata Phylum Mollusca Phylum Gastropoda I can't explain these phyla but maybe a week, I can see a reference book who has these definitions.
A phylum is the taxonomical rank below kingdom and above class. The kingdom Animalia contains approximately 40 phyla. Organisms are grouped into phyla based on a general body plan. For example, the phylum Chordata contains all those animals with a spinal cord. The phylum Arthropoda contains all those animals who are spineless and have an exoskeleton. The level of classification between kingdom and class.
Insects are animals. The animal kingdom is divided into phyla. One such phylum is Chordata, which holds the vertebrates - fish, amphibians, reptiles, birds and mammals. Another phylum is Arthropoda, which holds insects, arachnids, crustaceans and centi/millipedes. We're not exactly closely related, but we are both animals. Other phyla are Mollusca (slugs, snails, oysters, squids), Annelida (ringworms) and Cnidaria (jellyfish and corals), and many others... see how it works? :)
Invertebrates Animals without a Backbone or Spinal Column: Vertebrates Animals with a Backbone or Spinal Column: (All these animals are in the phyla Chordata and the subphyla Vertebrata.) Protozoa (phyla: protozoa) Fish (group: Pisces) Echinoderms such as starfish (phyla: Echinodermata) Amphibians such as frogs (class: Amphibia) Annelids such as earthworms (phyla: Annelida) Reptiles such as crocodiles (class: Reptilia) Mollusks such as octopus (phyla: Mollusca) Birds (class: Aves) Arthropods such as crabs, spiders and insects (phyla…
