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.

The Cellular Secret to Resisting the Pressure of the Deep Sea (quantamagazine.org)
The bottom of the ocean is cold, dark and under extreme pressure. It is not a place suited to the physiology of us surface dwellers: At the deepest point, the pressure of 36,200 feet of seawater is greater than the weight of an elephant on every square inch of your body. Yet Earth’s deepest places are home to life uniquely suited to these challenging conditions.
