Adam Hanlon: Mangrove forests in Raja Ampat. Mangroves are an important part of a healthy marine environment. That provide nurseries for young creatures and their falling leaves act as organic nutrients. #wetpixelexpeditions
Adam Hanlon: A gray seal wakes up after having a nap in the kelp at the Farne Islands, UK.
Adam Hanlon: A veined (coconut) octopus emerges from its shell home. Octopuses are intelligent and charismatic, curious about their environment and obviously capable of processing information about it. Taken during the @wetpixelgram / @alexmustard1 Macro workshop wit
Adam Hanlon: Another amazing day diving and photographing with the gray seals in the Farne Islands, Northumberland.
Adam Hanlon: More Nikon D500 goodness from the Wetpixel / Alex Mustard macro workshop at @crittersatlembehresort. A Nembrotha kubaryana nudibranch makes its way across an encrusting sponge. Taken using a Nudilab Moby diopter.
Adam Hanlon: Check out Wetpixel's detailed field review of the Nikon D500.
Adam Hanlon: The reefs of Raja Ampat, #indonesia host the richest biodiversity on the planet. Photographically, they present an amazing array of subjects and compositions. Taken during the @wetpixelgram Raja Ampat expedition on the @divedamai
Adam Hanlon: In keeping with my #trash theme, a pair of yellow ornate gobies has made their home inside a plastic bottle. By directing my flashes through the bottle, I was able to get this diffused lighting effect.
Adam Hanlon: Genie in a bottle! A fangblenny peers out of its adopted home in the Lembeh Straits, Indonesia. Muck diving is often carried out in areas that are not pristine, and it is interesting to note how animals carry out their own form of recycling.
Adam Hanlon: An enigmatic painted frogfish hides while bait fish school around it. Despite appearances, these are highly evolved ambush predators with several specific adaptions. Most noticeable is the esca or lure that has been fashioned from the first dorsal fin. T
Adam Hanlon: A tiger shark (Galeocerdo cuvier) makes lots of eye contact as it approaches. Sharks use a variety of sensors in order to make sense of their environment. These correspond to the proximity of the shark to the stimulus. They initially respond to scent stim
Adam Hanlon: Sunlight lights up the shallow reef, carpeted in basket stars on a reef in Komodo, Indonesia. The coral triangle has the greatest biodiversity of any marine area on the planet. Right at it's epicentre is Raja Ampat. It is amazing that I will be there next
Adam Hanlon: It is easy to figure out how the parrotfish got its name. This rusty parrotfish (Scarus ferrugineus) shows the dentition that allow these fish to scrape algae off corals in order to feed. This process is critical for the health of the reef. If the algae
Adam Hanlon: A playful gray seal mouthsthe dome port of my camera. Similar to dogs, seals seem acutely aware of how much pressure they can apply before "play" becomes "biting". Perhaps they learn this when socialising with other young seals. Animals that exist in larg
Adam Hanlon: Every day should be #worldwhalesharkday The biggest fish on earth (Rhincodon typus) is now on the IUCN's Endangered list. Loss of habitat, overfishing and boat strikes have made the populations of these amazing, gentle giants of the seas at risk of extinc
Adam Hanlon: A great hammerhead (Sphyrna mokarran) in the blue waters of the Bahamas. These sharks were added to the CITES Appendix II at the organisation's meeting in 2013. This makes trade in products from these sharks much more difficult. In 2016, CITES meets again
Adam Hanlon: Contrary to popular belief, temperate waters often are beautiful and vibrant. Here, photographer @alexmustard1 is surrounded by dead men's fingers (Alcyonium digitatum), a type of soft coral as he moves through the abundant kelp.
Adam Hanlon: During our recent trip to the #farneislands , I came across this gray seal resting in the kelp. I got very close, until he realised that I was there. He "barked" at me very loudly telling me to back off. The bubbles in the picture are actually from these
Adam Hanlon: You need a rear view mirror when diving with these guys! A gray seal inverts in my order to grab and tug at my fins. The seals at the #farneislands really enjoy this game, coming in and gently biting your fins in order to get a reaction! #underwaterphotog

Adam Hanlon: Flat calm, wonderful underwater visibility and lots of playful seals! A great combination #farneislands #seals #nikon #nikonpro #seacam #

Adam Hanlon: A zebra crab (Zebrida adamsii) on its host fire urchin (Asthenosoma varium). These crabs often exist in pairs on an urchin. They help remove parasites from it and in return the urchins poisonous spines protect it from predators. #nikon #nikonpro #seacam #
Adam Hanlon: A striated (hairy) frogfish waits patiently on the seabed for its next meal. Equipped with a highly modified dorsal fin which creates an illicium or rod, from which it dangles a lure or esca. In some parts of the world, this has lead to #frogfish being k
Adam Hanlon: "Sealed" with a kiss. Two gray seals cavort in the kelp. Diving with #seals is an amazing experience as, unlike most marine life, they seem to welcome clumsy bubble blowing humans into their midst. #farneislands #seals #nikon #nikonpro #seacam #wetpixel #
Adam Hanlon: A riot of color and life on the healthy corals in Egypt's #redsea. The anthias (goldfish) are a ubiquitous feature of the reefs, providing color and movement as they swarm around it. #nikon #nikonpro #bbcearth #seacam #underwaterphotography #instaanimal #
Adam Hanlon: Beautiful Wastwater in the UK's #lakedistrict. Britain's deepest lake is a great place to train divers for deeper diving.
Adam Hanlon: One of the features of diving in Egypt's #redsea at this time of year are the large schools of fish that aggregate in order to breed at Ras Mohammed on the southernmost tip of the Sinai desert. The confluence of the Gulfs of Aquaba and Suez have produced
