What are Sphenisciformes?

Sphenisciformes is the scientific order that includes all species of penguins. These flightless aquatic birds are primarily found in the Southern Hemisphere, particularly in Antarctica and surrounding regions. Penguins are known for their distinctive black and white plumage, adapted for swimming and diving in cold ocean waters. They are social animals, often living in large colonies, and they primarily feed on fish, krill, and other marine organisms.
