Scientists just identified the mysterious creature from 2009 footage as a ghost shark

  • Experts at the Monterey Bay
    Aquarium Research Institute have identified the mysterious creature they caught on camera in 2009 as a ghost shark,
    otherwise known as a chimaera.
  • Pacific Shark Research Center program
    director Dave Ebert called the discovery “dumb luck.“ 
  • The institute’s geologists spotted the animal off the Pacific coast of
    the U.S. via a remotely operated vehicle they plunged as far as 6,700
    feet beneath the ocean’s surface.
  • But at first, the researchers weren’t
    entirely sure of what they were seeing. Read more

Octopus Eyes Are Crazier Than We Imagined

by Maddie Stone

The latest fascinating cephalopod insights come to us from a
father/son team of researchers at the University of California, Berkeley
and Harvard University, who’ve learned that weirdly-shaped pupils may
allow cephalopods to distinguish colors differently from any other
animals we know of. The discovery is published this week in the Proceedings of the National Academies of Sciences.

Boring animals like humans and birds see color using a combination of
light-receptive cone cells, each of which contains pigments that are
sensitive to a different part of the visual spectrum. It’s only by
combining information from different cone cells that colors can be
properly distinguished. Hence, when a person lacks a particular type of
cone, he’s considered colorblind.

Cephalopods only have a single type of light receptor, which means
they should not be able to distinguish color at all. And yet, many
octopuses, squids and cuttlefish have color-changing skin that’s used
for elaborate camouflage ruses and courtship rituals. Clearly, these
colorblind animals have become masters of color manipulation. How? …

Deep in the ocean, a mission is underway to explore the “unknown and poorly known areas” around the Mariana Trench.

“Despite decades of previous work in the region,” the National Oceanic and Atmospheric Administration says, “much of the [trench] and surrounding areas remain unexplored.”

Between April 20 and July 10, the government agency and its partners are collecting and sharing data on the creatures and habitats they find in the Mariana Trench, which stretches 1,500 miles in the Pacific Ocean near Guam.

You can follow NOAA’s live video streams from the Okeanos Explorer, including images from the ocean floor.

It’s all pretty mind-blowing when you think about it, but here’s one of our favorites: A mesmerizing jellyfish found around 3,700 meters (2.3 miles) down (video above!).

“At the beginning of the video, you’ll see that the long tentacles are even and extended outward and the bell is motionless,” NOAA notes. “This suggests an ambush predation mode. Within the bell, the radial canals in red are connecting points for what looks like the gonads in bright yellow.”

Pygmy Seahorses: Masters of Camouflage

Tiny and delicate, pygmy seahorses survive by attaching to vibrant corals where they become nearly invisible to both predators and researchers. Now, biologists at the calacademy have successfully bred them in captivity for the first time. Finally, they’re able to study the seahorses’ amazing act of camouflage up close.

Better Than A Van Gogh: NASA Visualizes All The World’s Ocean Currents 

We imagine the ocean as having high tides and low tides, water that comes in and out in waves. Beyond that, how does water actually move around the world? What’s that flow look like?

NASA Scientific Visualization Studio assembled this remarkable animation of the surface currents of our oceans. It’s called Perpetual Ocean, and the full work is 20 minutes of HD video, assembled from a huge amount of satellite, on location, and computational data generated by ECCO2 (Estimating the Circulation and Climate of the Ocean, Phase 2). ECCO2 itself exists to better understand our oceans and their role in the changing global climate.

What you’re looking at is the surface current flow (not anything deeper) of oceans around the world, recorded from 2006 to 2007. The white lines are the currents, and the darker blue colors of the water represent bathymetry (the fancy word for misnomer “ocean topography”).

Lava reaching the sea from the Kilauea volcano in Hawaii

These piping hot pictures cost photographer Miles Morgan a tripod and pair of shoes, and almost turned him to toast when he came within a foot to capture lava reaching the sea from the Kilauea volcano in Hawaii.

Viper Moray Eel

This shot of a viper moray, a saltwater eel in the moray family, comes from a new exhibit at the National Museum of Natural History in D.C. called X-Ray Vision: Fish Inside Out. Read more about it here, or, better yet, just head to the museum. The exhibit’ll be there until August.
