Giant snakeheads can't live on land because they are fish and fish, as you know, have gills to breath under water...

The only fish species that i know of that lives out of water is the dead kind.
i recomed the gold fish or well i dont know what its name is but come kind of cleaner fish that sticks to walls that would keep the dirt and muck out of the way and under control
I only know of Marine Star fish.
i believe it is under it but i know its not directly at it because as light enters or leaves the water (which is denser than air) it is bent slightly
Whales don't lay eggs and they have to come up for air unlike fish which lay eggs and don't need to come up for air because they breathe under water.
it is used my SONAR. When something is underwater. I.E fish. The sound sends a frrequency to the fish, and it bounces back off the fish back to the SONAR. and thats how people know where to go and how to find stuff underwater
if you want to know if your fish has cancer, check if a certain place on your fish is puffy, or it looks like there is something under the skin (contact a fish store if so)
