A northern elephant seal pup curiously inspects its reflection in the glass dome of my underwater camera. It is always a very humbling experience when a wild animal decides that I am worthy of its curiosity. Once hunted to near extinction in Pacific Ocean, today the species has made a remarkable conservation comeback. Shot #onassignment for @natgeo in collaboration with @maresmexicanos

A very up close and personal look at Bohar snappers in one of the wild tidal channels of Aldabra Atoll. I am thrilled that this and five other photographs from my @natgeo magazine Seychelles story have won the 2017 Wildlife Photographer of the Year Portfolio Award #WPY53 Thanks to all my fantastic partners in the #Seychelles who made this @natgeo story possible: @sif_seychelles @saveourseasfoundation @birdislandlodge_seychelles @fregateislandconservation #islandconservationsociety


In this short video I freedive off Fernandina Island in the western Galápagos to photograph marine iguanas for @natgeo It was one of the most surreal moments of my life coming face to face underwater with these mini Godzillas. Video shot by the best assistant team a photographer could ever hope for. Thank you @ottowhitehead and @animal_ocean


Getting photographs of Indo-Pacific bottlenose dolphins in the surf zone was a bit tricky. To make this image I had to free dive in and out of the breaking waves. Exact timing meant the difference between getting the shot or getting pounded by the surf.

Blacktip reef sharks swim into the current as the tide drives water into Aldabra's giant Manhattan size lagoon. This remote Atoll belongs to the Seychelles and its conservation is expertly managed by @sif_seychelles. Inshore, sharks are unbelievably abundant and photographing there is almost like traveling back in time.........I would love hear about your favorite shark encounter - where, what species and why was it special?


On assignment for @natgeo photographing blacktip reef sharks in the near pristine waters of Aldabra Atoll. Still one of my all-time favorite wildlife encounters. Video shot by my fantastic assistant Otto. Please follow him @ottowhitehead for more behind the scenes videos and show him some love!


A great white shark crosses paths with a small school of silversides in the deep blue Pacific off Guadalupe Island, Mexico. A long camera exposure and flash creates a motion blur as shark and fish travel in different directions. Shot on assignment for the Sept 2017 @natgeo magazine feature Ocean Stewards. This story was shot in collaboration with @maresmexicanos and written by the very very very tall and talented @erikvance

BEFORE and AFTER my @natgeo assignment to photograph seabirds on some of the most remote islands on our planet. Time for a shave and haircut @natgeocreative #beards #beardsofinstagram #onassignment


A juvenile King Penguin on sub-Antarctic Marion Island investigates my camera. I left it on the ground for less than a minute before multiple youngsters came in at close range to investigate. Shot on assignment for @natgeo magazine on expedition with the South African Antarctic Program and the SA Department of Environmental Affairs.


One of the most expressive eyes in the animal kingdom zeros in for a closer look. I have photographed marine mammals for almost 20 years but never before have I experience an encounter this close. Can you guess what ocean animal this is just by looking at its eyeball? Send me you answers in the comments below. I will post the identity of the animal in 24 hours. Shot #onassignment for @natgeo magazine. ANSWER: Wow, we got more than 1000 guesses to try and identify the mystery animal just by its eye. A large number of you knew it was some sort of whale in fact more than 170 people thought it was a humpback. Fantastic to see that everyone here is so into marine wildlife. Humpback was a very good guess, but it was in fact a gray whale that I photographed in San Ignacio lagoon in Baja California, Mexico. Some of the more outlandish and interesting I.D's included a dairy cow and a rhinoceros
