What are the 3 classes of fish found in phylum Chordata?
The Chordata and Ambulacraria together form the superphylum Deuterostomia. Chordates are divided into three subphyla: Vertebrata (fish, amphibians, reptiles, birds, and mammals); Tunicata or Urochordata (sea squirts, salps); and Cephalochordata (which includes lancelets).
Is a fish in the Chordata phylum?
As members of the phylum Chordata, fish share certain features with other vertebrates. These features are gill slits at some point in the life cycle, a notochord, or skeletal supporting rod, a dorsal hollow nerve cord, and a tail.
Which animal is included in phylum Chordata?
Chordata is a familiar phylum that includes organisms like mammals, fish, birds, reptiles, and amphibians (all vertebrates); sea squirts (tunicates); and lancelets (cephalochordates). All chordates have a notochord, a dorsal nerve cord, and pharyngeal slits at some point in their development.
Why are fish chordates?
Fish are members of the chordate phylum because they display certain defining characteristics: a dorsal stiffening rod called the notochord • a dorsal nerve cord • pharyngeal gill slits • a tail that extends beyond the anus.
What are the 7 classes of Chordata?
The classes of the Phylum Chordata are the Amphibia, the Reptilia, the Fish, the Birds, and the Mammalia. Amphibians include frogs, salamanders, toads, newts, and some less familiar animals, such as caecilians.
In which fish Placoid scales are present?
Placoid scales are found in sharks and rays, and can vary greatly in external appearance. Unlike the scales of bony fishes, placoid scales do not increase in size as the fish grows, instead new scales are added between older scales. Placoid scales are often referred to as denticles.
What classifies a Chordata?
: any of a phylum (Chordata) of animals having at least at some stage of development a notochord, dorsally situated central nervous system, and gill slits and including the vertebrates, lancelets, and tunicates.
Are humans phylum Chordata?

Where did chordates evolve from?
It is thought that chordates evolved from a common ancestor of deuterostomes (echinoderms, hemi- chordates and chordates) by organizing these characteristic features.
When did chordates evolve?
Evolution of Chordates. The fossil record of chordates begins in the early Cambrian period, roughly 530 million years ago. The oldest known chordate fossil was found in China and described in 1995.
