A free diver exercises dynamic apnoea below an iced platform, in the chilly salt water of the White Sea, at minus 2 degrees Celsius. Must be extremely prepared, brave and self-controlled to free-dive, holding the breath, in ambient without a fast and clear access to the surface. Reaching the underwater world, is an adventure itself since a thick layer of ice bars the passages every night, due to very low temperatures, and every day one must cut ice holes (called mainas by locals) into the ice platform. Salted water needs very low temperature to freeze. Below the ice platform, the upper layer is a melt of fresh and salt water, allowing a surprising amount of life to thrive. Location: White Sea, northern Russia.

'Octopus Training', At the end of a session of free diving, I noticed a soccer ball, in the distance and on the surface. Intrigued I approached it, and then I noticed that below it was an octopus that was being pulled along by the current. I do not know what it was doing under the ball, but I think it is training for the next football World Cup! There was time for me to take a couple of shots before the octopus let go of the ball and dropped back to the seabed.

Free diver is swimming over a pod of Sleeping sperm whale (Physeter macrocephalus) Researchers first saw this unusual sleep behavior in sperm whales in 2008. The scientists in that study found that sperm whales dozed in this upright drifting posture for about 10 to 15 minutes at a time, Vulnerable (IUCN). The sperm whale is the largest of the toothed whales. Sperm whales are known to dive as deep as 1,000 meters in search of squid to eat. Dominica, Caribbean Sea, Atlantic Ocean. Photo taken under permit n°RP 16-02/32 FIS-5.

Visualization flow of water in a sponge - Aquarius Reef Base ; Fluorescein dye is used to visualize how water is absorbed at the outside and then exhausted by a sponge.The Caribbean barrel sponge, Xestospongia muta, is a large and common member of the coral reef communities at depths greater than 10 m, and has been called the “redwood of the deep”, due to its up to 2000 year lifespan as well as its size and color. Despite its prominence, high biomass and importance to habitat complexity and reef health, very little is know about the basic biology of this massive sponge, including rates of mortality and recruitment, reproduction, growth and age. Like reef corals, this sponge is subject to bleaching and subsequent mortality.
With support from NOAA's Aquarius Reef Base at UNCW, NOAA's Coral Reef Conservation Program, and the Florida Keys National Marine Sanctuary, a research group has been monitoring populations of X. muta in the Florida Keys since 1997.
