Superclass Tetrapoda

SUPERCLASS TETRAPODA

It is a superclass of the subphylum Vertebrata of the phylum Chordata.
These organisms have jaws with teeth.
These animals have two pairs of appendages, i.e., four appendages and hence the name tetrapoda.
Each of the appendages has five fingers.
The endoskeleton is made up chiefly of bones.
Generally, the respiratory organs are lungs.
