    Chordate - Wikipedia

    • A chordate is a deuterostomic bilaterial animal belonging to the phylum Chordata (/kɔːrˈdeɪtə/ kor-DAY-tə). All chordates possess, at some point during their larval or adult stages, five distinctive physical characteristics (synapomorphies) that distinguish them from other taxa. These five synapomorphies are a notochord, a hollow dorsa… See more

    History of name

    The name "chordate" comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate body plan structuring and movements. Chordates are also bilaterally symmetric, have a … See more

    Anatomy

    Chordates form a phylum of animals that are defined by having at some stage in their lives all of the following anatomical features:
    • A notochord, a stiff but elastic rod of glycoprotein wrapped … See more

    Classification

    The following schema is from the 2015 edition of Vertebrate Palaeontology. The invertebrate chordate classes are from Fishes of the World. While it is structured so as to reflect evolutionary relationships (similar to a … See more

    Subphyla

    Cephalochordates, one of the three subdivisions of chordates, are small, "vaguely fish-shaped" animals that lack brains, clearly defined heads and specialized sense organs. These burrowing filter-feeder… See more

    Phylogeny

    There is still much ongoing differential (DNA sequence based) comparison research that is trying to separate out the simplest forms of chordates. As some lineages of the 90% of species that lack a backbone o… See more

    Closest nonchordate relatives

    The closest relatives of the Chordates are believed to be the Hemichordates and Echinodermata, which together form the Ambulacraria. The Chordata and Ambulacraria together form the superphylum … See more

  1. Fish, amphibians, reptiles, birds, and mammals
    The phylum Chordata contains all of the animals that have a rod-like structure used to give them support. In most cases this is the spine or backbone. Within Chordata there are five classes of animals: fish, amphibians, reptiles, birds, and mammals.

    What is the phylum Chordata?
    The phylum chordata is named for the notochord, a longitudinal, flexible rod between the digestive tube and the nerve cord; in vertebrates, this is the spinal column. The chordates are also characterized by a dorsal nerve cord, which splits into the brain and spinal cord.

    What are the characteristics of Chordata?
    Chordates are also bilaterally symmetric, have a coelom, possess a closed circulatory system, and exhibit metameric segmentation. Although the name Chordata is attributed to William Bateson (1885), it was already in prevalent use by 1880.

    When did the vertebrate phylum Chordata begin?
    An extensive vertebrate fossil record begins about 400 million years ago. Embryological evidence places the phylum Chordata within the deuterostomes (bilaterally symmetrical animals with undeterminate cleavage and whose mouth does not arise from the blastopore), which also includes the phyla Hemichordata, Echinodermata, and Chaetognatha.

    Are urochordates and vertebrates part of the phylum Chordata?
    A separate clade, consisting of urochordates, vertebrates, and cephalochordates, has been identified as part of the phylum Chordata. Within Chordata, the clade formed by cephalochordates is considered the earliest, while urochordates and vertebrates form a sister group.

    Is Chordata a echinoderm?
    Chordata is a major phylum within the superphylum Deuterostomia, which also includes echinoderms, such as starfish and sea urchins. These two groups share a similar embryonic development pattern, but they differ significantly in their adult forms.

    Is Chordata a phylum of Xenacoelomorpha?
    Chordata, Ambulacraria, and possibly Xenacoelomorpha are believed to form the superphylum Deuterostomia, although this has recently been called into doubt. [ 10 ] Chordata is the third-largest phylum of the animal kingdom (behind only the protostomic phyla Arthropoda and Mollusca) and is also one of the most ancient taxons.
