In July 2018, scientists from four Russian institutions collaborating with Princeton University reported that they had analyzed about 300 prehistoric nematode worms recovered from permafrost above the Arctic Circle in Sakha Republic, and that after being thawed, two of the nematodes revived and began moving and eating.
The worms colonize the methane ice and appear to survive by gleaning bacteria, which in turn metabolize the clathrate. In 1997, Charles Fisher, professor of biology at Pennsylvania State University , discovered the worm living on mounds of methane ice at a depth of half a mile (~800 m) on the ocean floor in the Gulf of Mexico .

A paper by two Russian scientists in Global Health Action, a journal published by Umeå University in Sweden, had warned of the risk that the old burial grounds of cattle which had died to anthrax in the early last century may thaw and lead to the re-emergence of the viable pathogen.

Photographs of seahorses taken by scuba divers revealed evidence of a long-lost species of marine worm that hasn’t been seen since the mid-1950s, scientists say. Long-lost ocean worms photobomb ...
A cold seep (sometimes called a cold vent) is an area of the ocean floor where seepage of fluids rich in hydrogen sulfide, methane, and other hydrocarbons occurs, often in the form of a brine pool. Cold does not mean that the temperature of the seepage is lower than that of the surrounding sea water; on the contrary, its temperature is often ...
