Chordates Animals and Nature. 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.

- Urochordates are all marine, and are enclosed in a tough cellulose-like tunic (hence the common name tunicate Tunicates are members of the true chordates, and represent some of the most primitive ancestors of the Subphylum Vertebrata (see Fig, 2.14 - 2.18 in text).

What are protostomes and deuterostomes? Deuterostomes are also known as enterocoelomates because their coelom develops through enterocoely. There are four extant phyla of deuterostomes: 1  Phylum Chordata (vertebrates and their kin). 2  Phylum Echinodermata (sea stars, sea urchins, sea cucumbers, etc.).

Bony Fish Coelacanths. Class Osteichthyes Fish are all members of the phylum Chordata, sub-phylum Vertebrata. Fish are generally spindle-shaped, oval in section, and flattened either sideways or dorsal-ventrally. The skin is covered in protective scales, with some exceptions (lampreys, ocean sunfish).lass Osteichthyes Fish are all members of the phylum Chordata, sub-phylum Vertebrata.

- Chordates (Chordata) are a group of animals that includes more than 75,000 living species. Chordates are divided into three basic groups: vertebrates, tunicates, lancelets.

Cephalochordataâ Overview Comprehensive Description. The cephalochordates, or lancelets, comprise one of the three subphyla in the phylum Chordata (the other two being the vertebrates and tunicates). Lancelets are small fishlike animals that are generally less than 5 cm in length, although some reach 6 to 9 cm. Lancelets are found most commonly in shallow subtidal tropical, subtropical, and temperate sand flats, where they burrow in clean gravel or sand (not silty sediments) with just the head exposed.

General Biology/Classification of Living Things/Eukaryotes/Animals/Phyla This phylum consists of tunicates, lancelets, and the vertebrates. There are four major features that characterize the phylum Chordata. 1  A notochord, or a longitudinal, flexible rod between the digestive tube and the nerve cord. 2  In most vertebrates, it is replaced developmentally by the vertebral column.

- Taxonomically, the phylum includes the subphyla Vertebrata, which includes mammals, fish, amphibians, reptiles and birds; Tunicata, which includes salps and sea squirts; and Cephalochordata, comprising the lancelets.or the leaf shape, see Cordate. Chordates (/ˈkɔrdeɪts/) are animals possessing a notochord, a hollow dorsal nerve cord, pharyngeal slits, an endostyle, and a post-anal tail for at least some period of their life cycles.

- The current consensus is that chordates are monophyletic, meaning that the Chordata include all and only the descendants of a single common ancestor, which is itself a chordate, and that craniates' nearest relatives are tunicates.

Chordates Another characteristic of chordates is a structure called the endostyle, a ciliated groove on the ventral wall of the pharynx that secretes mucus and traps small food particles that enter the pharyngeal cavity.

- Most chordates are vertebrates. Invertebrate chordates, which belong to two of the subphyla of chordates—Cephalochordata and Urochordata, also have a dorsal tubular nerve cord, a notochord, pharyngeal pouches, a postanal tail, and, possibly, an ancestral thyroid gland. They ha ve no backbone, however.

Extremities In chordate animals a distinction is made between unpaired and paired extremities. In lower chordates (the larvae of tunicates and the lancelet) unpaired extremities are represented by a skin fold in which it is possible to distinguish dorsal, ventral, and caudal parts. Unpaired extremities are also formed in the larvae of cyclostomes, fish, and amphibians in the form of a common fold.

INVERTEBRATE MEMBERS OF THE PHYLUM CHORDATA Chordates are coelomate animals that possess: 1  a supporting rod or notochord; 2  a single hollow dorsal nerve cord; ‘ 3 metameric segmentation’: division of the body muscles into similar units, known as segments, that are arranged serially one behind the other;hey differ from the invertebrate chordates in possessing 1  : an internal skeleton, including a vertebral column which encloses the nerve cord; 2  a brain enclosed in a skull; 3  a pumping heart and efficient blood circulation.
