The Channa asiatica, small snakehead, is an invasive aquatic snakehead fish species native to parts of Asia and Africa. This fish gets its name from the long and cylindrical body and large scales on its body, giving them the snake's look.
The northern snakehead has also introduced and established its population in places like the United States and has disrupted the natural aquatic feeding structure in the ecosystem.
In the United States, there are four other species of Channa asiatica: Channa argus (northern snakehead), Channa micropeltes (giant snakehead), Channa marulius (bullseye snakehead), and Channa maculate (blotched snakehead). This fish is also amphibious in nature and can breathe both underwater and on the land.

What class of animal does a small snakehead belong to?
Snakehead channa belongs to the fish class of the family Channidae.
How many small snakeheads are there in the world?
Snakehead Channa reproduces very fast, making their population stable in the world. According to a study done in 2019, the population range for the fish species is from 22,000-51,000 in its native range only. Since the snakehead Channa is an invasive species, their introduced population range counts around 28,600-115,000.
Where does a small snakehead live?
The family of snakehead Channa is native to parts of Asia and Africa. The fish species is native to China, North Korea, South Korea, south Siberia, and Russia. Due to their invasive nature, they can now also be found in the United States, Central Asia, East Europe, and Japan.
What is a small snakehead's habitat?
Northern snakeheads are aquatic fishes found in freshwater streams, rivers, wetlands, or ponds. This fish species can also survive cold winter or a very low oxygen environment.
They are also capable of breathing atmospheric oxygen. They can change their habitats to a better preferable one by moving out of the water to land to find a better aquatic system for them. That is also why their preferred habitats are ones with slow-moving or stagnant water.
Who do small snakeheads live with?
Northern snakehead Channa prefers to live and hunt in groups called schools. In a closed environment, they can be kept with large species of catfish or peaceful cichlids. It is not advisable to keep smaller fish species with them.
How long does a small snakehead live?
In their wild habitat, snakeheads can live for at least eight years of age. Channa argus also has a special chamber adjacent to its gills, called the suprabranchial organ, that helps them breathe in air in low oxygen areas to help them survive outside of water for up to four days.
How do they reproduce?
Snakehead Channa reach their sexual maturity at the age of one to three years and reproduce through the process of spawning. These fish breed in the summer season from April to August spawn up to five times laying about 50,000 orange-yellow buoyant eggs per year.
However, their reproductive cycle has no specific details since their nesting behaviors differ from their native range to their introduced habitat. The northern snakehead fish are known to spawn in shallow waters with macrophyte cover, where they build their nests by first clearing the area and weaving aquatic vegetation into a column to hold and protect the eggs.
These floating nests are made using bits of vegetation also to protect their eggs.
Snakeheads are known to defend their young ones for several weeks and can attack people if they come closer. Snakehead fish parents stay with their young ones for up to four weeks.
What is their conservation status?
Small snakeheads are abundantly found in their native range and their introduced habitats, thus making their population very wide in the world. Therefore it is listed as Least Concern species by the IUCN.

'Kerala five strip.'
