Because they live in water, an environment which is completely foreign to us, but also because of their distance from us, their cold blood; their bodies covered with scales and their absence of expression, we often consider fish as dumb creatures of little interest, just good to be grilled. 

And yet! What diversity! What incredible abilities! What fantastic adaptations! Fish have conquered virtually all the aquatic environments of our planet, even the most extreme. They are capable of elaborate behaviors and of complex social interactions and they can express individual characters like shyness or boldness. Like birds, they communicate with elaborate sounds. We have too largely ignored these fascinating animals because we misunderstand them and their environment. This course will give you a much better and interesting vision of these animals and will also show you how a biological problem can benefit of being studied by different scientific approaches.
