Isometric has to do how the animals growth and in way does the animal growth. For isometric growth, animals growth occur only in surface area and not in height. For example, frogs grow isometrically because they increase their surface area and volume and mass does not increase. Proportionally, isometeric growth size and surface area are not proportional to each other. There is a difference in size between the childhood stage and the adult stage. Adults are larger in size than a child. This occurs over time. However, all of the body parts grow at the same rate. Another example is salamanders. In salamanders, the body parts all grow at the same rate. However, the juvenile stage size is different from an adult size. Therefore, salamanders grow isomerically.
