See 11 Adorable Babies Swimming Underwater

Seth Casteel, famous for his photographs of dogs underwater, is back with his latest book Underwater Babies. He was inspired to start this project after learning that drowning is the number one cause of accidental death for children under the age of five in the United States.

To create these photos, he teamed up with infant swimming schools throughout the United States, with each photo shoot happening during a swim lesson.
