Atlantic puffin with fish. Like many auks, puffins eat both fish and zooplankton but feed their chicks primarily with small marine fish several times a day. The puffins are distinct in their ability to hold several (sometimes over a dozen) small fish at a time, crosswise in their bill, rather than regurgitating swallowed fish.
The Atlantic puffin (Fratercula arctica), also known as the common puffin, is a species of seabird in the auk family.It is the only puffin native to the Atlantic Ocean; two related species, the tufted puffin and the horned puffin being found in the northeastern Pacific.
The chicks have a less varied diet, feeding mainly on sandeel or capelin from near the coast. These fish are distributed by the parents two to six times per day. [18] Unlike many other seabirds, which employ regurgitation to feed their young, horned puffins feed their chicks whole fish directly from the bill. [27]
Tufted puffins are around 35 cm (14 in) in length with a similar wingspan and weigh about three-quarters of a kilogram (1.6 lbs), making them the largest of all the puffins. Birds from the western Pacific population are somewhat larger than those from the eastern Pacific, and male birds tend to be slightly larger than females.

Some fish like carp and zebrafish have pharyngeal teeth only. [30] [31] Sea horses, pipefish, and adult sturgeon have no teeth of any type. In fish, Hox gene expression regulates mechanisms for tooth initiation. [32] [33] While both sharks and bony fish continuously produce new teeth throughout their lives, they do so via different mechanism.
