What are the three kinds of chordates?

Chordates are divided into three subphyla: Vertebrata (fish, amphibians, reptiles, birds, and mammals); Tunicata or Urochordata (sea squirts, salps); and Cephalochordata (which includes lancelets).

What are the 3 chordates?

Chordates consist of three distinct animal groups: cephalochordates, urochordates (tunicates) and vertebrates.

What are 3 types of primitive chordates?

Urochordata = tunicates or sea squirts. Cephalochordata = lancelets (amphioxus) Vertebrata = vertebrates (or Craniata: comprised of hagfish + vertebrates)

What are 3 main characteristics of the phylum Chordata?

Animals in the phylum Chordata share four key features: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.

What are the different classes of Chordata?

Chordata contains five classes of animals: fish, amphibians, reptiles, birds, and mammals; these classes are separated by whether or not they can regulate their body temperature, the manner by which they consume oxygen, and their method of reproduction.

What are the 3 major subphylum of Chordata give its characteristics and an example for each Subphylum?

Chordates are divided into three subphyla: Vertebrata (fish, amphibians, reptiles, birds, and mammals); Tunicata or Urochordata (sea squirts, salps); and Cephalochordata (which includes lancelets). ... Chordate fossils have been found from as early as the Cambrian explosion, 541 million years ago.

What are chordates and non-chordates?

The major point to differentiate between chordates and non-chordates is that chordates have a spinal cord or backbone in their body structure whereas non-chordates are without backbone or notochord in their body structure.

What are primitive chordates?

A primitive chordate gill is present in tunicates and cephalochordates, where it serves in both respiration and feeding. The vertebrate gill may retain some role in feeding, although the current is now produced by the action of muscles, not cilia.

Are starfish chordates?

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. The most conspicuous and familiar members of Chordata are vertebrates, but this phylum also includes two groups of invertebrate chordates.

What is the first chordate?

The oldest known fossil chordate is Pikaia gracilens, a primitive cephalochordate dated to approximately 505 million years ago.

What are the 4 main characteristics of chordates?

"The four distinctive characteristics that, taken together, set chordates apart form all other phyla are the notochord; single, dorsal, tubular nerve cord; pharyngeal pouches; and postanal propulsive tail.

What are Chordata characteristics?

Characteristics of Chordata. Animals in the phylum Chordata share four key features: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.

What are 5 characteristics of chordates?

Animals in the phylum Chordata share five key chacteristics that appear at some stage during their development: a notochord, a dorsal hollow (tubular) nerve cord, pharyngeal gill arches or slits, a post-anal tail, and an endostyle/thyroid gland (Figure 2).

How many chordates are there?

Of the more than 65,000 living species of chordates, about half are bony fish that are members of the superclass Pisces, class Osteichthyes.

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.

What are the three classes of subphylum Urochordata?

The Subphylum Urochordata includes a large number of species which exhibit high degree of biological diversities. The members are classified under three classes: Ascidiacea, Thaliacea and Larvacea or Appendicularia.
