They are the both in the same kingdom, phylum, class, and order but they belong to different taxonomic families. (worldatlas.com)
Frogs belong to phylum Chordata of the Amphibia Class . (worldatlas.com)
Amphibians1
They have a backbone just like all animals in the phylum Chor data.In evolution terms, reptiles are the intermediates between the warm-blooded mammals and the cold-blooded amphibians. (worldatlas.com)
Kingdom1
This kingdom is then broken down into over 30 groups, or phyla (plural form of phylum ). (yourdictionary.com)
Vertebrata2
Lizards (phylum Chordata, subphylum Vertebrata, superclass Tetrapoda, class Reptilia, order Squamata, suborder Lacertilia) are reptiles with a slender body covered by scales, four limbs (hence the superclass Tetrepoda which means "four legs") and a tail. (blogspot.com)
Chordata is broken down into diverse subphyla, commonly the three subphyla of Urochordata (tunicates), Cephalochordata (lancelets or amphioxus), and Vertebrata (although the hagfish , which lack vertebrae, are sometimes not classified in Vertebrata but their own subphylum of Myxini and in some taxonomies the subphlyum Craniata is used to include hagfish and other vertebrates).

Chordates4
Phylum Chordata - Phylum Chordata Charactertistics of Chordates All chordates possess a notochord. (powershow.com)
Chordates - Chordates Phylum Chordata Chordates What is a chordate? (powershow.com)
Chordate - Chordate Chordates (phylum Chordata) are a group of animals that includes the vertebrates, together with several closely related invertebrates. (powershow.com)
The original Linnaean system of classification did not include two major categories now in common use (phylum and family), but included all of the others (i.e., class, order, genus, and species). (surfnetkids.com)
Cnidaria1
Another way of looking at the phyla is shown in Figure 3, taken THE MOLECULAR BASIS OF EVOLUTION THE TIME SCALE AND SOME EVOLUTIONARY PRINCIPLES 3 Mollusca DEUTEROSTOMIA Echinodermata Primitive acoel flatworms BILATERIA Cnidaria Primitive medusa ee_) Giher Protoz0® Flagetlata Figure 2. (nih.gov)
Arthropoda1
Most documented animal viruses have been sampled from just two phyla - the Chordata and the Arthropoda - with a strong bias towards viruses that infect humans or animals of economic and social importance, often in association with strong disease phenotypes. (nih.gov)
Likewise, the sharing of a ventral nerve cord among species of particularly invertebrate phyla shows the unity within these taxon. (newworldencyclopedia.org)

Fossils1
At the end of the Pre-Cambrian, most of the in- / iz vertebrate phyla were relatively well differentiated, although the ab- 2 / sence in most instances of structural elements that could survive as a / fossils makes the reconstruction of their phylogenetic tree somewhat controversial. (nih.gov)
Order1
It is based on an arrangement of animals in order of structural complexity, without separation of the Years x1976 L- 4000 allied phyla. (nih.gov)
Vertebrate1
This arrange- Earth Scale Era ment of the phyla, which includes the higher vertebrate forms for comparison is, according to its author, L. H. Hyman, not to be taken literally but is only suggestive. (nih.gov)
Notochord2
Other distinguishing features of the Chordata phylum is that they all have, at some stage in their life, a notochord , a post-anal tail, an endostyle, and pharyngeal slits. (newworldencyclopedia.org)
or (2) the typically solid, ventral, double row of nerve fibers found in some phyla of invertebrates ( ventral nerve cord ). (newworldencyclopedia.org)
The ventral nerve cord is a bundle of nerve fibers, typically a solid double stand (pair) of nerve cords, that runs along the longitudinal axis of some phyla of elongate invertebrates , and forms part of the invertebrate's central nervous system . (newworldencyclopedia.org)
Among the phyla exhibiting ventral nerve cords are nematodes (roundworms), annelids (such as earthworms , and arthropods (such as insects and crayfish ). (newworldencyclopedia.org)
Major1
Here we see the major phyla, as they have existed through most of biological time, in terms of their relative abundances. (nih.gov)
