Greta Thunberg, the 17-year-old environment activist, has inspired thousands of people across the world, now, that effort has been offset, as two species have been named after her, and that list could probably increase.

From the forests of Nairobi, Kenia, and inspired by its labour, this tiny beetle has been named Nelloptodes gretae, and belongs to the Ptiliidae family, a highly diverse group of minute beetles, with over 400 species within, but is was stored unnamed in the Natural History Museum of Londo’s collection after it was collected in mid 60's , until late 2019, when is was formelly described and named by researches at  NHM.

- The tiny Nelloptodes gretae, measures 0.79 millimetres long, and it has no eyes or wings.

Greta's own passion has inspired other scientists, who named a microsnail as Craspedotropis gretathunbergae, honouring her. This tiny snail inhabit Borneo tropical rainforests, and is very sensitive to the droughts and temperature extremes that are likely to be more frequent as climate change continues, comment dutchs researchers at Taxon Expeditions, who made the discovery

Blind shrimps, translucent snails

By Jenny Davis, Charles Darwin University; Daryl Nielsen, CSIRO; Gavin Rees, CSIRO, and Stefanie Oberprieler, Charles Darwin University

There aren’t many parts of the world where you can discover a completely new assemblage of living creatures. But after sampling underground water in a remote, arid region of northern Australia, we discovered at least 11, and probably more, new species of stygofauna.

Stygofauna are invertebrates that have evolved exclusively in underground water. A life in complete darkness means these animals are often blind, beautifully translucent and often extremely localised – rarely living anywhere else but the patch they’re found in.

The species we discovered live in a region earmarked for fracking by the Northern Territory and federal government. As with any mining activity, it’s important future gas extraction doesn’t harm groundwater habitats or the water that sustains them.

Our findings, published today, show the importance of conducting comprehensive environmental assessments before extraction projects begin. These assessments are especially critical in Australia’s north, where many plants and animals living in surface and groundwater have not yet been documented.

When the going gets tough, go underground

Stygofauna were first discovered in Western Australia in 1991. Since then, these underground, aquatic organisms have been recorded across the continent. Today, more than 400 Australian species have been formally recognised by scientists.

The subterranean fauna we collected from NT aquifers, including a range of species unknown to science. A–C: Atyid shrimps, including Parisia unguis; D-F: Amphipods in Melitidae family; G: The syncarid species Brevisomabathynella sp.; H-J: members of the Candonidae family of ostracods; K: the harpacticoid species Nitokra lacustris; L: a new species of snail in the Caenogastropoda: M-N: Members of the Cyclopidae family of copepods; O: The worm species Aeolosoma sp. GISERA, Author provided

Stygofauna are the ultimate climate change refugees. They would have inhabited surface water when inland Australia was much wetter. But as the continent started drying around 14 million years ago, they moved underground to the relatively stable environmental conditions of subterranean aquifers.

Today, stygofauna help maintain the integrity of groundwater food webs. They mostly graze on fungal and microbial films created by organic material leaching from the surface.

In 2018, the final report of an independent inquiry called for a critical knowledge gap regarding groundwater to be filled, to ensure fracking could be done safely in the Northern Territory. We wanted to determine where stygofauna and microbial assemblages occurred, and in what numbers.

Our project started in 2019, when we carried out a pilot survey of groundwater wells (bores) in the Beetaloo Sub-basin and Roper River region. The Beetaloo Sub-basin is potentially one of the most important areas for shale gas in Australia.

What we found

The stygofauna we found range in size from centimetres to millimetres and include:

two new species of ostracod: small crustaceans enclosed within mussel-like shells

a new species of amphipod: this crustacean acts as a natural vacuum cleaner, feeding on decomposing material

multiple new species of copepods: tiny crustaceans which form a major component of the zooplankton in marine and freshwater systems

a new syncarid: another crustacean entirely restricted to groundwater habitats

a new snail and a new worm.

These species were living in groundwater 400 to 900 kilometres south of Darwin. We found them mostly in limestone karst habitats, which contain many channels and underground caverns.

Perhaps most exciting, we also found a relatively large, colourless, blind shrimp (Parisia unguis) previously known only from the Cutta Cutta caves near Katherine. This shrimp is an “apex” predator, feeding on other stygofauna — a rare find for these kinds of ecosystems.

Protecting groundwater and the animals that live there

The Beetaloo Sub-basin in located beneath a major freshwater resource, the Cambrian Limestone Aquifer. It supplies water for domestic use, cattle stations and horticulture.

Surface water in this dry region is scarce, and it’s important natural gas development does not harm groundwater.

The stygofauna we found are not the first to potentially be affected by a resource project. Stygofauna have also been found at the Yeelirrie uranium mine in Western Australia, approved by the federal government in 2019. More research will be required to understand risks to the stygofauna we found at the NT site.

The discovery of these new NT species has implications for all extractive industries affecting groundwater. It shows the importance of thorough assessment and monitoring before work begins, to ensure damage to groundwater and associated ecosystems is detected and mitigated.

Where to from here

Groundwater is vital to inland Australia. Underground ecosystems must be protected – and not considered “out of sight, out of mind”.

Our study provides the direction to reduce risks to stygofauna, ensuring their ecosystems and groundwater quality is maintained.

Comprehensive environmental surveys are needed to properly document the distribution of these underground assemblages. The new stygofauna we found must also be formally recognised as a new species in science, and their DNA sequence established to support monitoring programs.

Many new tools and approaches are available to support environmental assessment, monitoring and management of resource extraction projects. These include remote sensing and molecular analyses.

Deploying the necessary tools and methods will help ensure development in northern Australia is sustainable. It will also inform efforts to protect groundwater habitats and stygofauna across the continent.

💛Golden Mystery Snail🐌

Mystery snails are in the apple snail family that contains over 100 different known species!

Here’s a cool little guy commonly called a mystery snail. They’re in kingdom Animalia, phylum Mollusca, class Gastropoda, family Ampullariidae, genus Pomacea, and their scientific name is Pomacea bridgesii. 

They are known to live in the Paraguay and Amazon rivers. They’re active at night and enjoy swamps, ponds, lakes, and rivers. Mystery snails are bottom feeders and spend time usually in the open at the bottom of a body of water. 

They are often kept in aquariums

Mystery snails reproduce sexually. The female will then deposit the many fertilized eggs near the surface of the water. After 2 to 4 weeks, they will hatch and eat their way out of the egg. They feed on soft algae the first few days after hatching and soon will grow to be the same size as their parents!

Eggs ^

Here’s a video of some of the babies up close. 

Here’s another video showing some cute little baby mystery snails being fed in an aquarium. 

They have evolved from a common ancestor of gastropods,the Caenogastropoda.

Tracing the mysterious green flashes of light produced by a sea snail has revealed a creature built to shine from the inside – and with a shell that may be designed for communication as well as protection.  

Typically found in tight clusters or groups at rocky shorelines, the clusterwink snail, or Hinea brasiliana, was known to produce light. But scientists like Dimitri Deheyn assumed the sea snails did their light thing just like their pals on the land. Terrestrial snails produce a glowing light from their foot when it's sticking outside the shell.

Nerida Wilson of the Australian Museum in Sydney was working with the Hinea snail when she noticed these bright flashes and not the usual snail glow, so she contacted her colleague Deheyn, of the University of California-San Diego’s Scripps Institution of Oceanography, and sent him some snails.

The first difference he noticed upon receiving them was that, instead of glowing continuously, they produced light flashes that occurred only when touched.

Not only that, but when the snails retreated into their shells, as snails normally do when startled, they  continued to produce light – light that you could see on the outside of the shell.

The flashes are super-fast, Deheyn said, pulsating once every hundred milliseconds or less. And as long as you keep tapping the shell, the snail continues its psychedelic outpouring. "I have records of light flashes for like a half-hour, just flashes, flashes, flashes," Deheyn told LiveScience.
