Fin-tastic Facts About The Gollum Fish For Kids

Gollum fish facts that the fish was unknown to humans until 2018 when it surfaced in a paddy field in India.

A newly found species of fish, the Gollum snakehead, Aenigmachanna gollum, was just recently discovered. Scientists believe this species of subterranean fish, although recently discovered, has been on the earth as long as the dinosaurs and evolved at least 109 million years ago. It is genetically distinct from other snakeheads worldwide. Due to so many distinct features of the Gollum snakehead fish, it has been put into its very own new family, Aenigmachannidae. Scientists have even claimed that the Gollum snakehead might be a living fossil due to the species being on the world and evolving 109 million years ago.

The genus Aenigmachanna is a species of subterranean fish native to Asia and is predatory freshwater fish. It is endemic to the state of Kerala in India, where the species was discovered during the Kerala floods in the year 2018. The species were washed out of their hidden aquifers habitat and into a paddy field in Oorakam of Kerala. The pictures were posted on social media by the locals. The social media pictures were noticed by the Kerala University of Fisheries and Ocean Studies. As soon as the pictures were found, they prompted an inquiry into the new species. Among fish known from Kerala aquifers, this species is the eighth species found in the large, hidden ecosystem in the difficult habitat of Kerala.

What is a Gollum Fish's habitat?

The world has not seen the Gollum snakehead ever and did not know it existed up until 2018. The snakehead fish lives in the subterranean aquifers and comes to the surface only after heavy flooding of the water body. This new group of fishes are not at all evolved as they usually stay underground and are found in Asia and Africa. The family is not abundant in the subterranean aquifers of Africa. They are mostly found in India.

This group of Channa can thrive in low oxygen waters because of a special breathing organ that allows them to breathe air easily. They live in underground areas where there are caves made of stones.

How do they reproduce?

Usually, snakeheads lay around 15000 eggs in a season, and that can be one to five times a year. The Gollum snakeheads care for their babies a lot and guard the floating eggs. This makes them a successful group of fish that protects each other. Female snakehead lays the eggs and the eggs hatch in one to two days. Like a family, both parents guard the eggs with their lives.

Gollum Fish Fun Facts

What does Gollum Fish look like?

Evolved 109 million years ago, this subterranean fish called the Gollum snakehead has some distinctive features which keep them apart from other snakeheads. The Discovery of the Aenigmachanna fishes was carried out by Ralf Britz, V.K. Anoop, Neelesh Dahanukar, and Rajeev Raghavan, and they also laid out the information on the fish in their article. Rajeev, an assistant professor at the Kerala University of Fisheries and Ocean Studies, saw the news and social media post and immediately sent it to Ralf Britz. Ralf Britz then came to the Indian continent to collect the specimen and later identified it as a new species of snakehead fishes. Ralf Britz and his group described the Gollum fish as a snakeheads species with an incredibly long body, like an eel. The snakeheads have numerous scales along their body, a very long anal fin running along their belly and tail and the family of fish has lost the ability to maintain buoyancy in the water column. They have organs that allow them to breathe air deep underwater.

The Gollum snakeheads have a slender body-colored cinnamon-brown uniformly. They do not possess long canine teeth unlike other snakeheads in the family. Its swim bladder is shorter than other snakeheads. The swim bladder is an internal gas-filled organ that helps the fishes stay afloat in water. Unlike the other family of snakeheads, the Gollum snakehead is still primitive in its evolution.  

The Gollum snakehead fish is a part of the same genus as the snakehead.

Did you know...

Fishes that stay deep in caves and underground habitats are known as subterranean fish.

The Gollum snakehead or its Tolkienesque name Dragon snakehead was found in 2018 floating during Kerala floods into a paddy field.

The species was named after the character Gollum from J. R. R. Tolkien's 'The Hobbit' and 'The Lord of the Rings' book series. The character was also cave-dwelling, similar to our new species and hence, the name. Who can forget the character Gollum eating fish raw in 'The Lord of the Rings' movies! Gollum was one of the main characters in the Lord of the Rings franchise, which made the officials name this subterranean fish after the character.

The Gollum snakehead has a sister species called Mahabali snakehead, and both of them are said to dwell in underground freshwater aquifers connected to paddy fields in the Western Ghats of Kerala in India. The freshwater fish species have been studied extensively by scientists from India, Germany, UK, and Switzerland. But as the species was just found in 2018, the research is still going on and not much information has been found yet.

It is estimated that there are almost 32000 species of fish in the world. Many new ones are getting discovered like the Gollum fish.

Do they bite?

These fishes stay away from human contact and hence there are no cases of the Gollum fish biting anyone.

Do humans eat them?

Although the Gollum snakehead fish has not been found abundantly yet, many other snakehead fishes of the family are consumed by humans. The meat of these fishes is expensive and is firm, white, and flaky. This combination lets humans prepare their food in many different ways.
