The fish would dry out even if it is underwater.
The outermost layer of most fish is scales.
Mucus,spikes,scales.
Cleaner fish remove scales and mucus from their host.
The clown fish's body is covered with scales and mucus over them.
Fish are animals that have moist scales. This is due to a layer of mucus coating the scales. However, a minority of fish don't have any scales at all. Catfish and eels are examples of scaleless fish.
The purpose of slime coating is to protect the fish against disease, infection and minor damage.
Yes. Most fish have back bone.
Theyre are jellyfish and starfish to name a couple that do quite well without fins. Then there are all the shellfish too. I wonder though if you meant what would have happened if fish had evolved without fins. If that is the case then the best answer I can give is that life as we know it would not exist because fins were the beginning of legs/limbs. No fins = no legs = differently evolved species. Jellyfish, starfish and shellfish are not fish. They belong in different families and are not related to fish. The person above has no idea of what he or she is talking about.
Some examples of fish without scales include catfish, eels, and sharks.
Fish have a spine and are vertebrates. They have wet skins of scales that are covered with a mucus to guard against disease.
Most fish do in fact have scales, even some with scales that are nearly microscopic in size; many catfish however do not have scales, they have armour plating, but not scales.
