  • Structure: A streamlined body covered in scales for protection, fins for steering and movement, and gills for breathing oxygen directly from the water.

💡 Fun Facts

  • Gills: Gills are made of feathery filaments full of blood vessels. As water flows over them, they pull oxygen out, a bit like lungs in reverse.
  • Scales: Fish scales overlap like tiles on a roof, creating a flexible suit of armor. They are covered in a layer of slime that helps the fish glide through the water and protects it from germs.
  • Fins: A fish's tail fin (caudal fin) provides the main power for swimming, while other fins are used for steering, stopping, and hovering.
