Largest single-celled organisms found 6 miles under the sea
Researchers have found new examples of the strange singled-celled creatures called xenophyophores more than six miles beneath the surface of the Pacific in the Mariana Trench. At more than four inches in length, they are perhaps the largest single-celled organism on Earth. These protists make a living by sifting through sediments and can accumulate high levels of toxic metals like uranium, lead, and mercury.

STARFISH LARVA:
This starfish (magnification x 180) is in its second stage of larval development. The dimples mark where five arms will start to grow on a juvenile starfish.

SEA GHOSTS
“These remarkable creatures are still very much a secret world,” Kirby writes. Much scientific mystery still surrounds many plankton, including these sea anemone larvae (magnification x 100).

A gelatinous nudibranch (Janolus barbarensis) adds a splash of color to the ocean in Morro Bay, Calif. Nudibranches are ocean-dwelling mollusks without shells; they’re often called sea slugs, but some sea slugs are in a family of their own, unrelated to the 3,000 or so species of nudibranch.

Digitized Deep-Ocean Expedition Discovers Surprising Oasis of Life
Marine biologists have discovered a never-before-seen duo of organisms colonizing a deep-sea hydrothermal vent in the Atlantic Ocean.
The team discovered the unlikely duo of shrimp and tubeworms, neither of which can rely on sunlight at the bottom of the ocean to power a food chain below them. Instead, the creatures have evolved to harbor chemosynthetic bacteria that feed on rich nutrients that billow from hydrothermal vents. [Read More]

What does this 3-mm crustacean have in common with a whale?
According to new research, they both regulate buoyancy in the same way: with a ‘diving belt.’
The stores of oil in the copepods work in a similar way to how some marine biologists think whales change their buoyancy at different depths: as the copepods swim deeper to their winter retreats, the increased pressure causes their oily body fluids to solidify. As the oil transforms into a more buttery substance, the copepods gain neutral buoyancy preventing them from constant swimming in deep waters. This saves the creatures’ energy.
