The rhinoceros auklet (Cerorhinca monocerata) is a species of seabird mainly found in North America and parts of Asia like Japan and Korea. Their range includes California, South Dakota, the Aleutian Islands, Alaska, Hokkaido, Washington, and the Pacific coast. They are the only species left in the order Charadriiformes and they are in the Alcidae family and have the genus of Cerorhinca. Rhinoceros auklets are also known as unicorn puffins and horn-billed puffins. They are closely related to puffins like the tufted puffin.

Rhinoceros auklets, like all auks, are diving birds and hunt for food underwater. Their main diet involves small fish, particularly schooling fish species and crustaceans. They tend to return to the shore only during the breeding season when the rhinoceros auklet is known to create nesting colonies. They create these nesting colonies in close vicinity to each other and hunt and fly in flocks. These nesting birds lay their eggs in deep burrows and usually lay only one egg each breeding season. Rhinoceros auklets are dark gray on the upper side and pale gray below. They have a sharp bill with a white horn as well.
