Scientists discover life in environment long thought to be too hostile to thrive VIDEO

A recently discovered microscopic animal in the sediments of the Great Salt Lake in the US state of Utah is revealing a hidden layer of life that scientists had completely overlooked.

The shoreline of the Great Salt Lake in Utah often appears almost deserted. The lake’s extreme salinity limits the number of animals able to survive there, and most research has focused only on a few well-known species, as highlighted in an article by The Daily Galaxy.

Tiny crustaceans Artemia franciscana, better known as brine shrimp, fill the water in massive seasonal swarms.

Along the shoreline, brine shrimp reproduce in dark mats that cover the edge of the lake. Together, they provide food for millions of migratory birds that use the lake as a feeding ground. But all this time something else had been quietly living in the mud beneath the water.

Scientists from the University of Utah collected sediment samples from several locations in the lake. Between grains of mud and salt crystals they discovered microscopic roundworms — animals belonging to the group known as nematodes. These organisms are among the most abundant animals on the planet.

They inhabit soils, oceans, freshwater lakes and even deep underground environments. Despite their widespread presence, scientists had never confirmed their existence in this hypersaline lake — a place often considered too salty for many animal species.

The researchers found that the worms are permanent inhabitants of the lake rather than accidental visitors. During the analysis, they also identified several different types of roundworms. This diversity suggests that more than one species has adapted to the lake’s harsh chemical conditions, with each species potentially occupying slightly different ecological niches within the sediments.

By feeding on microbes and breaking down organic remains, the worms contribute to nutrient cycling in soils and aquatic sediments. Their movement also helps mix the finest layers of sediment, influencing how oxygen and nutrients move across the lakebed.
