Animals that live in cold climates must avoid losing heat to survive. Animals with a minimum amount of surface area exposed to the environment can better conserve body heat. Penguins have cylindrical shape.
Find the efficiency ratio for each penguin. Which one lives in a colder climate?
Galapalagos: 0.371
King: 0.203
King penguins have a smaller efficiency ratio, so they can live in colder climates
