The Chordata is the animal phylum with which everyone is most familiar, because it includes humans and other vertebrates. Not all chordates are vertebrates, however. All chordates have pharyngeal slits, a dorsal nerve cord, a notochord, and a post-anal tail, even if these are only found in the embryonic form of the animal.
The oldest chordate is believed to be Haikouichthys, which lived around 530 million years ago during the Cambrian period. It had a primitive notochord but lacked true vertebral elements.
Yes, a dolphin is a chordate. Chordates are animals that possess a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail at some point in their life cycle, all of which dolphins have.
There are three main types of chordate eggs: oligolecithal eggs (with minimal yolk), mesolecithal eggs (with moderate yolk), and telolecithal eggs (with abundant yolk). Each type of egg provides nutrients for the developing embryo in different ways and affects the development of the embryo.
A Chordate is a animal with a notochord. They do not need to have spines- they just need to have a spinal cord. Fish, Reptiles, Mammals, Birds, and Amphibians are all members of the Chordate phylum. There are also invertabrates closley related to these members of the Chordate phylum that are Chordates.
The postanal tail in chordates serves various functions, including aiding in swimming and balance, providing propulsion, and assisting in movement and maneuvering in the water. It is one of the defining features of chordates, along with the notochord, dorsal nerve cord, and pharyngeal slits.
A vertebrate is a type of chordate. For example In the phylum Chordata they're are three subphyla, Urochordata, Cephalochordata, and Vertebrata. Vertebrates fall in the subphyla Vertebrata.
