A Strange Underground Fish Was Recently Discovered in India

A team of researchers has made a stunning discovery in underground waters in southern India. They found living members of a family of eel-like fish, which is named dragon snakeheads. These primitive fish are considered a “living fossil” because they are believed to have diverged from their relatives some hundred million years ago.

The Dragon Snakehead Joins a New Family of Fish

The Gollum Snakehead Fish In taxonomy, the family is the category placed above genus and species, and discovering a new one is not very common. Usually, taxonomic families are large and diverse, but the new fish family includes only two species. The first one is named the Gollum snakehead, after the famous Lord of the Rings character, and the dragon snakehead is now the second member of this family.

The study leader Ralf Britz shared that he believes this might be the most exciting discovery in the fish world for the last decade. These long-bodied fish usually dwell in aquifers of porous rock, which explains why they are rarely seen. They would only come to the surface after heavy-rain floods.

The fish live in the Western Ghats of southern India, which is known as a biodiversity hot spot. In the aquifers there, scientists have discovered ten new species of subterranean fish. However, the water there is used for around six million wells, and this lowers the water table, putting some of the obscure species that call it home in peril.

Enigmatic Fish Species

Enigmatic Fish Species Back in 2018, researcher and study co-author Rajeev Raghavan saw a photo of an odd fish that was retrieved from a backyard well. He and Britz had no idea what the species, genus, and family of the fish were and described it as a new species and genus – Aenigmachanna Gollum or the Gollum snakehead. During a similar and more recent discovery, Britz and his colleagues thought they found the same fish in another well. After performing further research on their genetics and anatomy, they found they belong in a whole new family.

The new dragon snakeheads exhibit a series of primitive characteristics, and these unique traits include fewer vertebrae with ribs, a shortened swim bladder, and a lack of a suprabranchial organ. These features show that the dragon snakeheads are not as specialized as regular snakeheads and can really be called “living fossils.” Genetic analysis showed that dragon snakeheads diverged from their nearest relatives over 120 million years ago when Africa and India were still the same landmass.

Global Clean-Energy Investments Reaching a Record High in Technology

clean-energy examples - solar panels and a wind turbineAccording to a BloombergNEF report released on the 14th of January, there are more than $500 billion in clean-energy technologies investments, and this is the first time ever for such peaks. The technology sector has always been expected to increase in capital, and investing in clean energy is definitely a big step.

Clean-Energy Technologies Are Expanding

Global energy transition investment, 2004-20If the world is to adequately address climate change, such investment highs should just be the beginning in the technologies that are making energy and other materials cleaner. It’s Clean-energy technologies

Clean-energy investments are accelerating due to a series of overlapping factors, such as increasing political goals (including the US elections) and falling costs.

VC Investments Are Also Breaking Records

Venture capital investment in climate tech, globally - 2009-2020The BloombergNEF report comes on the heels of a previous one, showing that the venture capital investments are also breaking records. The report shows that the VC investments in technologies are majorly aimed at combating climate change.

Low-carbon energy investment reached $501.3 billion in 2020, which is 9% more than in 2019. What’s interesting is that despite the ongoing world pandemic, this is a significant increase.

The tally also includes investments in renewables, energy storage, electric vehicle charging stations, carbon capture projects, hydrogen production, and more with the largest areas of investment being renewable energy and electrical transportation.

It’s Too Good to be True

There’s always a but to every good statement. In this particular case, the big problem is that the report mentioned above reflects another border trend, which is that investment often lags in technologies beyond renewable electricity and electric cars. As already stated, a huge portion of the investments goes to carbon capture and industrial processes such as cement.

Carbon emissions, factory However, this is still good news and if the clean-energy trends keep up, an even bigger increase will be reported next year according to the International Energy Agency.
