How is the fish able to survive in water?
Adaptations for Water
Fish have gills that allow them to “breathe” oxygen in water. Water enters the mouth, passes over the gills, and exits the body through a special opening. Gills absorb oxygen from the water as it passes over them. … They are typically long and narrow, which reduces water resistance when they swim.

Do fish have voices?
Fish don’t have vocal chords, so they vocalize using two different anatomical methods. The first is when a fish uses its muscles to drum or vibrate its swim bladder, an internal organ that helps fish control their buoyancy.
Can clownfish live in freshwater?

Do fishes cry?
