What is the largest class of Chordata?

Vertebrates are the largest group of chordates, with more than 62,000 living species. Vertebrates are grouped based on anatomical and physiological traits.

Which class is the most abundant vertebrate?

The bony fish (A) is the most abundant and diverse of the extant vertebrates. The members of the bony fish, actinopterygians, dominate the vertebrates and the fishes species in total.

What are the 5 major classes in the phylum Chordata?

The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds.

Which is the smallest class of phylum Chordata?

So under Phylum Chordata, there are Class Reptilia, Amphibia, and Class Mammalia, which humans fall under. This grouping keeps getting smaller and smaller until we get down to species. So a kingdom is a very large group, and phylum is a smaller group, and species is a single type of organism.

Does the phylum Chordata include vertebrates or invertebrates?

The most familiar group of chordates is the vertebrates. However, in addition to the subphylum Vertebrata, the phylum Chordata also contains two subphylums of invertebrates: Urochordata and Cephalochordata.

Which vertebrate group has the most species?

Fish (including sharks) make up the largest group of vertebrates. Nearly half of all vertebrates are fish. Fish have been swimming in Earth's water for more than five hundred million years- longer than any other kind of vertebrate has been on Earth.

Which group of vertebrates comprises of highest number of species?

Complete answer: Mammals have the highest that is, 177 endangered species among vertebrates which represents 3.8% of all the species.

What are the three major phyla of Chordata?

(a) Traditional view. The prevailing view holds that the phylum Chordata consists of three subphyla: Urochordata (Tunicata), Cephalochordata and Vertebrata (figure 1a).

What are chordates Class 9?

A chordate is an animal belonging to the phylum Chordata; they possess a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail, for at least some period of their life cycle.

How are chordates classified further?

They are bilaterally symmetrical, triploblastic, coelomate with organ-system level of organisation. Phylum Chordata is divided into three subphyla: Urochordata or Tunicata, Cephalochordata and Vertebrata. Subphyla Urochordata and Cephalochordata are often referred to as protochordates and are exclusively marine.

Which is the largest phylum of animal kingdom?

arthropod, (phylum Arthropoda), any member of the phylum Arthropoda, the largest phylum in the animal kingdom, which includes such familiar forms as lobsters, crabs, spiders, mites, insects, centipedes, and millipedes. About 84 percent of all known species of animals are members of this phylum.

How many species are in the phylum Chordata?

The phylum Chordata consists of both invertebrate and vertebrate chordates. It is a large and diverse phylum. It includes some 60,000 species.

How is a mammal classified?

An animal is considered a mammal if it can produce milk. Other features unique to mammals include hair or fur (chemically different from hairlike structures on non-mammals); the malleus, incus, and stapes in the ear; and a diaphragm separating the heart and lungs from the abdomen.

What are birds classified as mammals or reptiles?

Snakes, lizards, turtles, crocodilians, and birds are reptiles. Like all vertebrates, reptiles have bony skeletons that support their bodies. Scales help prevent reptiles from losing water through their skin.

Which animals are classified as chordates give examples?

Chordates (Chordata) are a group of animals that includes vertebrates, tunicates, lancelets. Of these, the vertebrates—lampreys, mammals, birds, amphibians, reptiles, and fishes—are the most familiar and are the group to which humans belong.
