Photographer Seth Casteel's underwater photographs have captivated an international audience, from our best companions in Underwater Dogs and Underwater Puppies to some of the decade's most innovative animal photography. Now, after what are among the most joyful shoots of his career, Seth has found a remarkable new way to capture images of our youngest humans at their most playful and pure: underwater.

A beautiful gift book with more than 70 previously unpublished photographs, Underwater Babies reveals adorable babies as they explore the underwater world, chubby-cheeked, curious, mischievous, and joyous, all in Casteel's signature style.
