Answers

Any of a subphylum (Vertebrata) of chordates consisting of animals (such as mammals, birds, reptiles, amphibians, and fishes) with a bony or cartilaginous spinal column that replaces the notochord.

The vertebrates are frogs and fish.

What are the characteristics of vertebrates?

  • The anatomy of vertebrates is strikingly similar, with the presence of a vertebral column, gastrointestinal tract, and spinal cord.
  • The notochord develops into a vertebral column, with the vertebrae on the dorsal side.
  • The presence of the central nervous system is an important indicator. The spinal cord's anterior nerve tube expands into the brain.
  • Jaws can be found in some vertebrates. Jawless species are included in the order of vertebrates.
  • The internal skeleton facilitates the distribution of various muscle attachment nodes.

Why frogs and fishes are vertebrates?

  • Frogs and fish are both members of the phylum Chordata and the subphylum Vertebrata.
  • Frogs and fish, like humans, have a spinalcord and a backbone.
  • Furthermore, all chordates have bilateralsymmetry.
