A great white shark rises from the depths to explore a companion shark cage at Guadalupe Island, Mexico. The white shark populations at Guadalupe are wonderful shark ambassadors located a moderate boat ride away from San Diego for those who wish to learn more about these majestic creatures in their natural environment. * With @the_explorers_club@thephotosociety@aboutsharks *

Photograph by @PaulNicklen taken while on expedition in Svalbard, Norway // I am asked all of the time to show proof of the effects of a warming climate on Arctic ecosystems. One of the most shocking ones, was this polar bear I found lying dead on the shore of Spitsbergen. While I was still coming to terms with this loss, I looked up and found a second dead polar bear lying nearby. These two bears died in an area of Svalbard that historically has had sea ice year round. A scientific report was later released that they had starved to death due to a lack of sea ice. There are places in Svalbard that are already ice free for up to 6 months a year and without this floating platform from which to hunt, bears are simply unable to catch seals. For #MoreOcean#follow my 2017 return to Svalbard on my @paulnicklen feed as we continue to document this year's disappearing sea ice and its effects on this polar ecosystem.

A swell shark embryo called a pup grows inside a rubbery sac attached to a piece of seaweed. The pup will feed on the round yolk until it emerges in 9+ months depending on water temperatures. The empty case sometimes wash ashore and are called a "mermaid's purse"
Swell sharks get their name from their ability to ingest water to double their size to discourage predators. //

Repost from @natgeo - Photo by @jenniferhayesig A mushroom shaped iceberg glistens in the sun drenched sea off Ilulissat Western Greenland. The name of the town literally means "iceberg" in Kalaallisut (a dialect of Greenlandic language). This iceberg was born in the the Ilulissat Icefjord, a UNESCO World Heritage Site and one of the most active glaciers in the Northern Hemisphere. Greenland's icecap contains +10% of the worlds freshwater supply and is melting at unprecedented pace as temperatures continue to rise. Icebergs are temporary sculptures in the sea, I photographed this formation last week and as I swam away to photograph a tabular berg the mushroom shaped iceberg broke up and vanished.
