Puffins are members of the seabird family called alcids.
The Atlantic puffin is only one of three kinds of puffins. The horned puffin and the tufted puffin are found in the Pacific Ocean. It is estimated that there are 15 to 20 million pair of puffin in the world. Puffins resemble penguins as their white underbelly contrasts their black coat. This coloring is a form of camouflage called counter shading.
