What about other schools of fish? Do they have leaders?

Dolphins live in a tribe.There can be up to 150 dolphins in each tribe.The mother is the centre of the family.\n\nWhen hunting they use a method called "Kettle technique".\nThey manage to gather the fish together into a ball shape by letting out piercing cries and by surrounding them with bubbles. In this way it is very easy to catch them.\n\norcas work in co-operation with one another, swimming in unison to create a wave pattern in an attempt to knock the seals off of the ice. This clever hunting technique quickly and efficiently could provide dinner for a pod of orcas.\n\nI once read about a incident where the orcas followed a young blue whale and its mother for 4 days and when it got exhausted they had eaten it.The mother was too big for them and they could possibly not harm it.

Sensory and nervous system\nFishes have well-developed nervous systems that organize around a central brain, that is divided into different parts. The most anterior, or front, end of the brain are the olfactory bulbs, which are involved in the fish's sense of smell. Unlike most vertebrates, the cerebrum of the fish primarily processes the sense of smell rather than being responsible for all voluntary actions. The optic lobes process information from the eyes. The cerebellum coordinates body movements while the medulla oblongata controls the functions of internal organs. Most fishes possess highly developed sense organs. Nearly all daylight fish have well-developed eyes that have color vision that is at least good as a human's. Many fish also have specialized cells known as chemoreceptors that are responsible for extraordinary senses of taste and smell. Although they have ears in their heads, many fish may not hear sounds very well. However, most fishes have sensitive receptors that form the lateral line system. The lateral line system allows for many fish to detect gentle currents and vibrations, as well as to sense the motion of other nearby fish and prey. Some fishes, such as catfish and sharks, have organs that detect low levels electric current. Other fishes, like the electric eel, can produce their own electricity.

from a moron ar the bottom of the food chain that's pretty funny.  they do three things and they do them better than anybody else.  they eat, and make baby sharks, the third is a by product of the eating thing.  BTW they've been around-unchanged-for somewhere around 70 million years.  not bad for a retard, huh.

Tilapia is a good food fish to raise. Ornamental fish (like bettas) being in a lot of money as well. Look for University Extension Offices in your area for free information & good workshops. The following publications will help.

That is not a good question. A cladogram expresses the ancestor-descendant relationships by means of _branches_, not by means of an ascending or ordered system. Thus, a goldfish would not come "before" a horse, nor a lamprey before a platypus. All the animals in your list do not even belong to a single nested group of taxa.\nThe sparrow is more related to the crocodile, the horse with the human and they in turn with the platypus, but all them, as well as lampreys, frogs, goldfish,  have their own evolutionary histories and their phylogenetic relationships are more complex than that.\nTell that to your teacher!

for bait id say minnows and salmon eggs. they love 'em. for lures run spoons, spinners, rooster tails, even some rapala minnows will get eaten by the big ones.\n\ngood luck and leave a few for me!

Rotifers   are the only I can think of  now if it were Phylum Mollusca it could be Snails, Clams, and squids\n                                 good luck

I don't think Finding Nemo set out to portray ocean life accurately. It's a fantastical story. As far as fish communication, I'm sure it exists, but not in the form of "talking." Fish communicate through body gestures most likely, and possibly some other means such as body secretions or even sound production. \n\nWhatever the means, though, fish communication is almost certainly centered around extremely basic topics such as keeping a school together or coordinated hunting in the case of larger fish like sharks.

I prefer FLW other than bass masters. FLW is a better chance for an everyday fisherman to have fun and be able to fish against some of the best. As far as bass masters being better fisherman, the best fisherman fish both.I think what did it for me was when bass dropped Ranger Boats and went with Triton. Also starting out with FLW you fish tournaments against other pros or amateurs . Bass you join a club , real crappy way to do it. That is a long story on how that works , more complicated.

Great question!\n\nFish have what we might call the "beginning" of a cortex.  Non-vertebrate chordates do not.  It should be noted that cephlopods have a nervous system that rivals a cortex (certainly surpasses that of fish).

Fish have a what is known as a slime coat, or mucous layer all over thier body. This layer is continually rubbed off and worn off. It helps keep of bacteria and some parasites.\n\nSome fish with take a brief sabd bath or mud bath on the bottom substrate. While others enlist the aid of others. Many large marine fish will have a cleaner shrimp or cleaner wrasse pick off parasites.\n\nIn general fish do not get dirty, so there is no real reason for them to keep clean.\n\nThey have a slime coat for protection against cuts and scrapes and parasites, and that is all they need.

Think of an ant on top of mount everest,thats relationship between a fish and the ocean.There are over a a trillion fish in the ocean.

I found this article on parasites and fish.  Hope it helps.\n\nhttp://www.charkbait.com/article/RAPC2.htm

All I can say there are plenty of fish in the pond, keep looking there are more than you think. Unless you want the big meaty ones... they are hard to find and mostly for mature fishermen.. :)
