Galapagos Penguin

The Galapagos penguin with a population of a little over 1,000 makes this the rarest penguin in the world.  They have a special setting of veins and arteries, as well as less dense plumage to help regulate their body temperature with the constantly changing temperature of the water in the Galapagos.  Penguins breed only during the cold months and are flightless birds.  They are a great example of incredible biodiversity due to their unique location.  In addition to their other distinctive factors, they have behavioral adaptations such as panting, and hopping in water to deal with the harsh heat since they are sub-Antarctic birds.
