Stunning Antarctic Sea Creatures Discovered After Iceberg Breaks Away (scientificamerican.com)
A large sponge, a cluster of anemones, and other life is seen nearly 230 meters deep at an area of the seabed that was very recently covered by the George VI Ice Shelf in Antarctica. Sponges can grow very slowly, sometimes less than two centimeters a year, so the size of this specimen suggests this community has been active for decades, perhaps even hundreds of years.

Scientists predict and witness evolution in a 30-year marine snail experiment (phys.org)
Snails on a tiny rocky islet evolved before scientists' eyes. The marine snails were reintroduced after a toxic algal bloom wiped them out from the skerry. While the researchers intentionally brought in a distinct population of the same snail species, these evolved to strikingly resemble the population lost over 30 years prior.

Plankton balloon to six times size in newly discovered mode of oceanic travel (phys.org)
Many plankton journey from the cold, dark depths of our oceans to the surface, only to eventually drift down again into the darkness in a perpetual rhythm. Yet, how single-celled phytoplankton, most of which have no appendages to help them swim, make this pilgrimage has remained a mystery.

Tubeworms live around deep-sea vents (economist.com)
HYDROTHERMAL VENTS are the planet’s exhaust pipes. Kilometres below the ocean surface, they relentlessly belch out searing hot water rife with harsh chemicals from beneath Earth’s crust. When they were first discovered in 1977, nobody expected these inhospitable sites to bear signs of life. And yet, thriving alongside these vents were colonies of tubeworms, mussels and clams entirely new to science. It is hard to think of an environment that could be more hostile.
