Yes, however they may require a fuel not created by themselves.

well in rivers, smallmouth go by areas where a boulder breaks the current, beacuse bait fish and crayfish get caught up in the current then the smallmouth come up and eat them. in lakes, smallmouth hang out around rock piles and grass beds to feed on mainly crayfish and then come up to the surface to feed on minnows and shad

An Angler Fish eats fish, srimps and crustaceans. There is a huge diffence between the female angler fish and the male. He eats smaller portions at younger age; because he is very small compare to the female.

The Female can grow up to 47 inches and the male only to 2.5 inches. Saying this when the male is grown enough, if he attached himself to the female by bitting her skin that will be HIS LAST BITE!

For that moment on he will mate forever with that Female and will depend on her for everything including nourishemnt(feed). Their bodies will become one and the only way that the male can feed is attaching himself to the female blood streamed; and this is for the rest of his life. He will lose all his organs including his eyes.

The angler fish male does not have a digest tube.

the cat to the monkey to the dog to elephant to the fish to the mouse to the ant then to the blue tangs.

I know this isn't much, but the fish is so small it can fit through the teeth of other fish that are bigger than it in the rock pool. Also the fish has gills which allows it to swim far down in the water and stay in the water because one of its predators (the seagull) can't go in the water. Lastly, the fishes scales tend to be dark green so they can camouflage. But say the fish is a florescent color then because its small it can squeeze into small rock gaps.

near the end of a food chain but pikes eat them....

You can make it as simple or as complicated as you wish:-) I'm in the UK, so am able to fish around the Med several times each year, as a part of vacation trips, and the methods vary very little from country to country. If you are in an urban centre / city, it is possible / probable that you will be able to take part in organised fishing trips on board a boat, which can be anything from dangling a line overboard to big-game fishing. Most fishing probably takes place from shores / breakwaters, in harbours etc ... and remember, tides are not really an issue in the Med, as for all intents and purposes, they do not exist!:-) Fishing methods can range from the lightest rod that you own, with a naural bait (virtually anythiung edible!), to a powerful rod capable of casting 5 ounces (160grams) well over 150 yards / metres .. or anything in between, including the full range of lure / baitcasting rods. It REALLY is that flexible .. take what you have and simply enjoy yourself .. like the world over, you'll find that anglers talk to each other:-)

Food

All the other animals would die on the food web because there food disappeared! its a chain reaction

if grasshoppers were removed which would suffer the most a bird or a baboon
