Batrachoididae is a big word that means a family of fish. Just like how you have a family with your parents and siblings, fishes also have their own family with their parents and siblings.
These fishes are special because they can make a noise, just like how you can talk and sing. They use their special organs called swim bladders to produce this noise.
Batrachoididae fishes are also very good at hiding. They have special colors and patterns on their bodies that make them blend into their surroundings, kind of like how you might wear camouflage clothes to blend in during a game of hide-and-seek or while playing in the woods.
Some Batrachoididae fishes are even able to breathe air just like you do! They have a special organ called a "pseudo-lung" that helps them breathe when they come up to the surface of the water.
So there you have it, Batrachoididae is just a fancy word for a family of special talking, hiding, and air-breathing fishes!
