I find that very good for the fish's to be kept in school, not only they can be kept away from predators, just like Monica said. Its no different from African wild dogs. African wild dogs run away from predators together because they know who to follow, instead for them looking around because they know when one runs they all run. here is the link. http://www.awdconservancy.org/ Good job Aurora!

Just like the others have previously commented, fish swim in schools for ecological advantages as well as survival and reproduction advantages. According to an article posted about observations collected from researchers at Penn University, schooling is now considered a form of imprinting. As baby and young fish, they swim together in pairs or in very small groups. But, when the fish reach adulthood, they swim in larger groups called schools. The behavior is also innate because it is strictly based on the genes of the fish, and every individual of the same species "schools" in the same exact way. On the other hand, to answer Aurora's second question, fish of different species do not school together. As others have stated, the advantages of schooling pertain to the specific species because there are predator advantages, energy reduction, and more mating opportunities only within that one species.

Before researching more about the topic, I was trying to come up with another logical reason for why the fish swim in schools. I was thinking, similar to what you had mentioned, that the fish who swim alone are much much more vulnerable and more likely to get eaten by a predator, than a fish who is swimming among hundreds of other fish. It could also cause the predator to become overwhelmed at the number of fish and also become distracted by their sudden and rapid movements. When researching, I found that the schooling process goes unnoticed among young fish and they don't even realize what is happening. It kind of comes quite naturally to them. They also use vision to be synchronized with the other fish, and they also have hair-like receptors that help them to move through the water. It is also beneficial for a fish to swim in a school because it makes it becomes easier to scare off a predator. Fish, like many other organisms, are genetically programmed to know that safety lies in numbers. I really loved this post, Aurora! http://scienceray.com/biology/marine-biology/why-do-fish-swim-in-schools/ This was truly fascinating, Aurora.

I agree there are multiple benefits for fish to travel in schools. A benefit for swimming in schools that i found in my research are that there is a better chance of surviving if a fish is more focused on a whole pack, then one specific fish. I think that a fish is unable to swim with a separate species, because a fish is commonly attracted for a favorable fish. If more then 1 species of fish is traveling in a pack that would attract more predators of different species.

When fish create a wagging motion the create a displacement in water that allows the fish behind it to move a higher speed, these small currents are called vorticles. When the water around the fish is moving quickly it takes less energy for the fish itself to move. While traveling in a school fish can cover larger distances! http://scienceray.com/biology/marine-biology/why-do-fish-swim-in-schools/ Fish also swim in schools because they create a huge water current that helps eachother move.

Not only is it able to find a mate in large crowds, but it is also harder for a predator to locate one single fish which it turn increasing a fish's odds of survival. I find it interesting that a similar process occurs with human beings. when there is a large crowd, we all move in oone giant group when a group is scared or nervous. This way, it is harder to pick out a single person. Birds also travel incrowds http://freshaquarium.about.com/cs/beginnerinfo/a/schooling.htm the schooling of fish is a great evolutionary advantage for the species.

This is so fascinating! I did a little more research on schools of fish and found out that it has been discovered that schools of fish take on the same overall shape. According to a study performed by Andrew Brierly of the University of Saint Andrews in Scotland, it was observed that Antarctic krill fish maintained a constant surface area to volume ratio. Although the size and density of the group varied significantly, the shape of the swarm of the fish remained the same. To explain this discovery, reseachers used computer technology to come to a simple solution. The researchers tentatively came to the conclusion that the shape of the school of fish depends solely on the amount of oxegyn in the water, along with the fishes' instict to remain protected from predators, as Aurora began to explain earlier. http://www.sciencedaily.com/releases/2010/09/100916121320.htm Below are some interesting photos of Schools of Fish: http://photography.nationalgeographic.com/photography/photos/schools-fish.html#/orange-basslets-laman_18408_600x450.jpg Great post Aurora!

I also did some research after read your post. I find that some fish that swim in schools secrete a slime that helps fish in their school reduce the friction between their body and the water, making it easier for them to swim.I think it's very interesting, then I know that fish are not born to swim, they also need to learn how to swim. There's some fish that are better then others. Fish only swim in schools with fish of the same species. I guess it's because that the different species have different color and size, so they can not do synchronization very well. And it doesn't work when the different species go together.

I did a little research and found out many cool facts that I never knew about fish and their schools. I learned that a school of fish could have as many as one million members, and usually, the members are of the same species. I was always curious about that, and my research clarified it for me. I also found out that fish swim in schools, not only for protection, but because they are family. For example: Piranhas swim in schools, even though they are very tough, and if a piranha from a different family tries to join that school, the other piranha will kill him. Did you know that 20% of the fish population do not swim in schools? I thought that all fish swim in schools, but it turns out that some fish, such as Clown fish or swim in solitude. http://freshaquarium.about.com/cs/beginnerinfo/a/schooling.htm http://findarticles.com/p/articles/mi_m0EPG/is_n12_v28/ai_16817882/ Great post Aurora!

This truly is a unique way for fish to protect themselves. After researching this topic, I learned that there is variability between how long fish swim in schools. Whereas some of them only swim in schools right after they are born, some stay in schools for their entire lives. As for Taylor's question, it is easier for fish to find food when they are traveling in schools because it is more likely for a large group of fish to spot food than it is for one or two of them to find some on their own. http://findarticles.com/p/articles/mi_m0EPG/is_n12_v28/ai_16817882/ Awesome post, Aurora!
