No, you're not tripping. And these aren't CG. You're looking at Portuguese man-of-war jellyfish captured by Florida-based photographer Aaron Ansavor who finds them on a local beach.
"It's an opportunity to explore a new world," he told National Geographic.

The southern sand octopus (Octopus kaurna) whips up some seafloor "quicksand" lined with mucus and burrows into it to rest during the daytime. From New Scientist:
(University of Melbourne researcher Jasper) Montana and his team first caught the octopus in the act of burrowing in 2008 when they were scuba diving at night in Port Philip Bay, south of Melbourne, Australia. When they shone a light on the octopus, the startled animal spread out its arms and repeatedly injected high-powered jets of water into the sediment using its funnel. This caused grains of sand to be temporarily suspended in water, making it like sandy water.
“The sediment became fluid like quicksand,” Montana says. The octopus put its arms into the sand while still pumping out water and eventually dived down into the sediment. The liquefied sand is likely to reduce drag and so allow the animal to burrow more quickly, using less energy, Montana’s team speculates....
They (later) found that the animal used its arms and mantle to push the sand away and form a burrow. It also extended two arms to the surface to create a narrow chimney to breathe through. Finally, it secured the walls of its new home with a layer of mucus that kept the grains of sand together so the entire thing maintained its shape.

Robyn Malcolm captured this wonderful photo of a fur seal surfing on a humpback whale off Eden, Australia.
"We'd seen some amazing whales coming out of the water, everything was happening so quickly," Malcolm told the Sydney Morning Herald. "And it was when I went back through the photos that I realised I had actually captured the seal on top of the whale."
Geoff Ross, a whale expert at New South Wales National Parks and Wildlife Service said the only other time he'd heard of this happening is when a seal was attempting to escape an orca. Read the rest
Humpback whales doing what they do, off Moss Landing, California. They kayakers were fine. From the YouTube post:
On our 08:00 am Sanctuary Cruises whale tour, just outside the harbor in Moss Landing, two kayakers on a tandam kayak were almost crushed to death by a massive, near full-size humpback whale. We stopped to see a large aggregation of humpbacks feeding and carrying on with random acts of hijinks. There were also a lot of kayakers right in the middle of it all. Humpbacks were coming up next to and in the middle of many kayakers. It was amusing. It's all fun and games until someone gets jumped on. The next thing we knew, this thing launched right on top of these two kayakers. That was heavy. The video was shot by Sanctuary Cruises passenger Larry Plants.

A few months back, Marianne Winkler found a bottle on a German beach with a message inside requesting its return to the Marine Biological Association (MBA) that had dropped more than 1,000 bottles into the North Sea as part of a study of currents. Thing is, that experiment took place more than a century ago. From National Geographic:
"We haven't had [a bottle] returned in living memory," says Guy Baker, an MBA spokesperson.
(Former MBA president and lead researcher on the bottle study George Parker) Bidder got about half of his messages back, says Baker. And the longest it took for one of his bottles to come home—before this current one—was about four years....
Bidder's bottle has also been submitted to the Guinness World Records for consideration as the oldest message in a bottle ever recovered. The current record-holder is a 99-year-old bottle discovered in a fishing net off the Shetland Islands in 2013.

This fantastic video from the World Wildlife Fund in Australia is a turtle’s eye view of the The Great Barrier Reef. The sensitive ecological zone is home to almost 6,000 species.
To find out more about the level of pollution affecting turtles within the Great Barrier Reef, WWF is working on innovative project in Queensland with the support of our partners Banrock Station Wines Environmental Trust, James Cook University, The University of Queensland, the Great Barrier Reef Marine Park Authority, State and Commonwealth government agencies, Indigenous rangers and local community groups.
As part of that project, the opportunity arose to very carefully fit a small GoPro camera to a turtle, to better understand the post-release behaviour of tagged green turtles. The result is this amazing video.
This week, the World Heritage Committee will vote whether to keep a strong watch over Australia until the health of the Great Barrier Reef. The decision is critical to the future protection of the Reef.
