Fish are full of surprises! Here are some unique facts about them:
Some fish can walk on land: The mudskipper spends much of its life out of water, using its pectoral fins to "walk" on land.
Parrotfish sleep in a mucus cocoon: This slimy sleeping bag protects them from predators by masking their scent.
Some fish communicate with sounds: While they don’t have vocal cords, species like the croaker and toadfish produce sounds by vibrating their swim bladders.
The clownfish can change sex: If the dominant female in a group dies, the largest male will transform into a female and take its place.
Sharks predate dinosaurs: Sharks have been around for over 400 million years—long before the first dinosaurs appeared!
The underwater world never ceases to amaze.
