The word "Channidae" refers to a family of predatory fish commonly known as snakeheads. Being a scientific name, it may not be familiar to everyone, but there are several synonyms that may ring a bell. For instance, these fish are often called "freshwater sharks" due to their razor-sharp teeth and their ability to breathe air, which allows them to survive out of the water for short periods. They are also known as "walking fish" because they can move on land using their fins. Additionally, in some countries, they are referred to as "dragon fish" or "snake fish" due to their distinctive features and behavior.
