Reptilia : possess 3 - chambered heart with one incompletely divided ventricle.
Chordata : Possess a mouth provided with an upper and lower jaw.
Chondrichthyes : Possess cartilaginous endoskeleton.
Mammalia : Give birth to young one.
A : Biradial, organisms is divided into unequal halves by any plane through the central axis.
B: Bilateral, body is divided into equivalent right and left halves by only one plane.
A: Asymmetrical, organisms is not divided into equal halves by any plane through the central axis.
B: Radial, in which any plane passing through the central axis of the body divides the organism into two identical halves.

They are bilaterally symmetrical, triploblastic and coelomate animals.
Body is covered by a calcareous shell and is unsegmented with a distinct head, muscular foot and visceral hump.
The mouth contains a file-like rasping organ for feeding, called radula.
