Cave Diver, Anhumas Abyss, Bonito, Brazil: The Anhumas Abyss is an underground cavern with a crystal-clear lake below, more than 260 feet (79 m) deep. A visitor must enter through a narrow opening at the top of the chamber and rappel into the cave. Snorkeling and scuba diving in the lake reveal amazing scenery.

“24.27 N, 81.44 W. These coordinates mark the spot of the final resting place of an old brave soldier, the USS General Hoyt S. Vandenberg. In 2009 it underwent a complete change when the creaky steel monster became a mystical bearer of secrets. In May of that year, the Vandenberg was lowered down into the darkness of the ocean off the coast of Florida to become an artificial reef, where it would dwell in rigor mortis at a depth of 130 feet. This lively, animate, secretive nothingness, this menacing, wild emptiness would haunt and seduce the renowned Austrian photographer and passionate diver Andreas Franke...”. – The Sinking World (Photo by Andreas Franke)

Californian photographer and conservationist Octavio Aburto had spent years photographing the school in Cabo Pulmo National Park, Mexico – and had been trying to capture this exact shot for three years. “Together with my friend David Castro, we were diving with a large group of Bigeye travellies at Cabo Pulmo National Park, Mexico. Thousands of fish forming a ball during the reproduction courtship. In the afternoon, these fish congregate to form a large spawning aggregation around the reefs of the National Park”.

“The series of photos called Workwears, by French photographer Bruno Fert, visually juxtaposes people’s private lives with their lives at work. A firefighter, a fisherman, a nurse, a diver, a judge. One by one, Fert’s photos show people in their homes wearing everyday clothing – followed by another photo showing them dressed in the clothing of their chosen professions. Our reaction, Fert said, reminds us how tightly humans hold on to certain stereotypes about some professions. “I like to break those stereotypes”, he said”. – Thom Patterson via CNN.

“David Doubilet (born 28 November 1946) is a well known underwater photographer known primarily for his work published in National Geographic Magazine. He was born in New York and started taking photos underwater at the young age of 12. He started with a Brownie Hawkeye in a rubber anesthesiologist's bag to keep the water out of the camera. During his summer holidays, he spent his time along the New Jersey coast. He later worked as a diver and photographer for the Sandy Hook Marine Laboratories in New Jersey. He also spent much time in the Caribbean. While a dive instructor in the Bahamas he found his motivation to capture the beauty of the sea and everything in it”. – Wikipedia.
