What animals belong to Chordata?
The Phylum Chordata includes the well-known vertebrates (fishes, amphibians, reptiles, birds, mammals). The vertebrates and hagfishes together comprise the taxon Craniata. The remaining chordates are the tunicates (Urochordata), lancelets (Cephalochordata), and, possibly, some odd extinct groups.
Which of the organisms is not in the phylum Chordata?
However, we share this phylum with two groups of invertebrates as well. Tunicates (subphylum Urochordata) and lancelets (subphylum Cephalochordata) are the only invertebrate groups within the phylum Chordata. Figure 3.97 shows some invertebrate representatives of the phylum Chordata.
What animal category is a tiger?

1) Chordata refers to a large phylum of animals that includes vertebrates as well as lancelets and sea squirts. Several well-known vertebrates, such as reptiles, fishes, mammals, and amphibians are included in the phylum Chordata.
Is a lion a chordate?
A lion is a Chordate – Phylum Chordata – it has a spinal cord.
Which organism is not in the phylum Chordata?
Is a giraffe a chordate?

: any of a phylum (Chordata) of animals having at least at some stage of development a notochord, dorsally situated central nervous system, and gill slits and including the vertebrates, lancelets, and tunicates.
What animal family are giraffes in?
Giraffids
Giraffe/Family
Giraffidaegiraffes and okapis. This family includes only two living species, the giraffe and the okapi.What species is giraffe?
Giraffa camelopardalis
Currently, giraffes are all know as species Giraffa camelopardalis, and up to 11 sub-species are recognized, including the Nubian giraffe (Giraffa camelopardalis camelopardalis).What kind of animals are in the phylum Chordata?
Animals that belong to the phylum chordata include all species of vertebrates and two groups of invertebrates. The vertebrates include: birds, fishes, mammals, amphibians and reptiles, while the invertebrates include: Urochordata (tunicates) and Cephalochordata (lancelets).
What are animals that do not have the notochord?
Animals that do not have the rod – like structure called the notochord in their body are termed as non – chordates. Essentially, this phylum includes the animals like marine species as well as the members of the phylum Porifera, Hemichordata, Echinodermata, Mollusca, Arthropoda, Annelida, Aschelminthes, Platyhelminthes, Ctenophora and Coelenterata.
What are the physical characteristics of a chordate?
Characteristics of Chordates. The deuterostomes, whose name translates as “second mouth,” consist of two phyla: Chordata and Echinodermata. Echinoderms are invertebrate marine animals that have pentaradial symmetry and a spiny body covering, a group that includes sea stars, sea urchins, and sea cucumbers.
What kind of gill slits do chordates have?
3) All chordates possess, at some stage of their development, gill slits or pharyngeal clefts. In the primarily terrestrial vertebrates these are lost during embryological development. 4) All chordates possess at some time in their lives a post anal tail, i.e. an elongation of the body beyond the end of the digestive tract.
What do all animals in Chordata have in common?
Chordata is a familiar phylum that includes organisms like mammals, fish, birds, reptiles, and amphibians (all vertebrates); sea squirts (tunicates); and lancelets (cephalochordates). All chordates have a notochord, a dorsal nerve cord, and pharyngeal slits at some point in their development.
Which phylum of animals is most related to chordates?
The closest relatives of the chordates are probably the hemichordates , since these animals possess gill slits and other features not found in other animal phyla. A slightly more remote relationship to the echinoderms is inferred on the basis of resemblances between the larvae in some groups of hemichordates and echinoderms.
What animal is a chordate but not a vertebrate?
There are animals that are chordates but not vertebrates. Tunicates and amphioxus are two animals that are chordates but not vertebrates. Acorn worms have also be classified as chordates, not vertebrates.
What are other organisms classified in the phylum Chordata?
Chordates are divided into the following taxonomic groups: Lancelets (Cephalochordata) – There are about 32 species of lancelets alive today. Members of this group have a notochord that persists throughout their entire life cycle. Tunicates (Urochordata) – There are about 1,600 species species of tunicates alive today. Vertebrates (Vertebrata) – There are about 57,000 species of vertebrates alive today.
