Headline is to publish photographer Seth Casteel’s Underwater Babies.
Deputy publishing director Sarah Emsley acquired UK and Commonwealth rights, excluding Canada, for the book from Little, Brown US.
Casteel’s previous books, also published in the UK by Headline, have captured images of dogs and puppies underwater.
Underwater Babies will contain “a stunning new collection of portraits, 80 previously unpublished photographs of adorable babies, safely photographed underwater in an environment natural to them”.
Emsley said: “There is something magical about Seth's groundbreaking and iconic photographs. We are thrilled to remain his UK publisher.”
Underwater Babies will be released on 23rd April 2015, costing £14.99.
