Animal photographer Seth Casteel captures images of dogs diving into a swimming pool with reckless abandon. While all of the photos are impressive, what's most interesting (or disturbing) is how the photos combine the childlike delight of these dogs with what looks like terrifying scowls on their faces as they hone in on their play toy targets

Casteel has also posted a video of "Nevada the Diving Dog," a Border Collie determined to fetch a tennis ball as it descends to the bottom of a swimming pool. You can purchase copies of Casteel's underwater dog photography here
