How to identify striped snakehead
Channa striata · Channidae
The characters that identify striped snakehead, ranked by how far each one can be trusted on its own.
Safety: injury while handling fish — minor injury.
How this was identified, and who took it
Identified by: The dark chevron blotching along the lower flank is the character separating Channa striata from its congeners, and it is unambiguous here. The long spineless dorsal and anal fins, the rounded tail and the flattened head plated with enlarged scales place the fish in Channa; the absence of a caudal ocellus rules out great snakehead.Reyes, R.B., CC BY 4.0, via Wikimedia Commons — source, licenceLook at this first
Turn the fish so you can see below the lateral line. Striped snakehead carries dark chevrons along the lower flank, pointing forward towards the head. Great snakehead has an eyespot at the tail instead, and giant snakehead has two bold bands down the side.
Diagnostic — settles it on its own
Each of these settles the identification on its own. If one is clear, you have your answer.
Forward-pointing chevrons on the lower flank
Oblique dark bars angled towards the head, running along the belly side of the lateral line. It is the pattern that separates this species from the other Channa likely to be in the same water, and it is legible on a fish of almost any size.
Supporting — use with other characters
Real characters that are not conclusive by themselves. Use two or three together.
No eyespot at the base of the tail
Great snakehead carries a conspicuous ringed ocellus there and this species does not. An absence, and a useful one, because the two overlap across much of South and South-East Asia.
Long spineless dorsal and anal fins on a cylindrical body
Both fins run most of the body length and neither carries a spine. This establishes the genus before any species character is applied, and it rules out the eels and elongate catfish that share the same swamps.
Build and maximum size
More slender and considerably smaller than giant or great snakehead. A very large snakehead in the same water is probably one of those two rather than this one — a probability rather than a determination.
What it gets confused with
- Great snakehead, separated by the caudal eyespot and by size.
- Giant snakehead, which as an adult carries two bold dark bands along the flank.
- Other Channa across South and South-East Asia, several of which are separated on scale and fin ray counts rather than on pattern.

Where this stops working
Channa is a large and taxonomically active genus, and several species are separated on counts that a photograph cannot supply. Juveniles of several snakeheads converge in appearance. Where the fish is outside its native range the identification carries an obligation rather than only an interest: introduced snakeheads establish readily, and their air-breathing lets them survive transport in a way most fish cannot.

Safety
Injury while handling fish — Minor injury
Snakehead teeth are small but sharp and the fish remains active and strong out of water for a long time.
What reduces it: Use pliers rather than fingers, and control the fish against a soft surface.
