Consigli per l'identificazione

1. 1

   Head Shape

   The most distinguishing feature is their flattened, snake-like head, which gives them their common name. This is particularly noticeable when viewed from above.

2. 2

   Dorsal and Anal Fins

   Observe the long, continuous dorsal and anal fins that lack spines. This differentiates them from many other predatory freshwater fish.

3. 3

   Body Markings

   Pay attention to the specific patterns, spots, or stripes on the body, as these are often species-specific and crucial for identification within the Channa genus.

4. 4

   Air Breathing

   If observed in the wild, their habit of surfacing to gulp air is a strong indicator of a snakehead. This behavior is unique among many freshwater fish.
