What is the name of group of Chordata?
chordate, any member of the phylum Chordata, which includes the vertebrates (subphylum Vertebrata), the most highly evolved animals, as well as two other subphyla—the tunicates (subphylum Tunicata) and cephalochordates (subphylum Cephalochordata).
What is the largest and most diverse chordate class?
Subphylum Vertebrata – “Backboned.” This is the largest and most diverse subphylum of chordates whose evolution has been guided by the basic adaptations of the living endoskeleton, efficient respiration, advanced nervous system, and paired limbs.
What is the name of a generalized Chordata?
Which group of chordates is the most diverse?
Which chordate class has the most species?
Vertebrates are the largest group of chordates, with more than 62,000 living species. Vertebrates are grouped based on anatomical and physiological traits. The traditional groups include Agnatha, Chondrichthyes, Osteichthyes, Amphibia, Reptilia, Aves, and Mammalia.
Which of the following is a name of group 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. More than one classification and naming scheme is used for these animals.
How many species of 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.
How many species of chordates are there in the world?
Of the more than 65,000 living species of chordates, about half are bony fish of the superclass Osteichthyes. The world’s largest and fastest animals, the blue whale and peregrine falcon respectively, are chordates, as are humans.
Which is a part of the phylum Chordata?
A chordate is any member of the phylum Chordata which includes three sub-phyla; Vertebrata (vertebrates), Urochordata (tunicates) and Cephalochordata (lancelets). Chordates usually have a notochord (a stiff dorsal supporting rod) at some stage of their development. In vertebrates, this develops into spine.
Where are the earliest fossils of chordate found?
All of the earliest chordate fossils have been found in the Early Cambrian Chengjiang fauna, and include two species that are regarded as fish, which implies that they are vertebrates.
Attempts to work out the evolutionary relationships of the chordates have produced several hypotheses. 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.
