The flippers of penguins have at least three branches of the axillary artery, which allows cold blood to be heated by blood that has already been warmed and limits heat loss from the flippers. This system allows penguins to efficiently use their body heat and explains why such small animals can survive in the extreme cold.
The Galápagos penguins' flipper-like wings and streamlined bodies enhance their easy movements in water. [14] Their white and black colors also aid in thermal regulation and camouflaging.
