Thank you for your nice post about fish body parts. Here is a picture about fish body. http://www.gastrojosesoler.com/pez%20antomia%20interna.jpg Diversity of habitats Fishes occupy almost every conceivable aquatic habitats. Certain species abound in the lake cipronodóntidos extensive world's highest, Lake Titicaca on the border between Peru and Bolivia (3.810m), other species were found at the bottom of deepest lake, Lake Baikal (1.637m of depth) in Russia and in the deep ocean (at 7.000m deep). On a hot spring in Mexico, ciprinodóntidos tolerate temperatures up to 45 º C, while some Antarctic fish lives about -2 º C, the water does not freeze at these temperatures because of its high salt content, and the fish manages to live because their blood contains a form of biological antifreeze. Some fish live in freshwater nearly pure, while some tolerate salinities cipronodóntidos four times higher than the sea. The cave fish can spend a lifetime in complete darkness, while those in the swamps of the wilderness experience maximum solar irradiation. A group of South American annual fish survive the periodic loans drying of their habitat through the dry season as dormant eggs, leaving them and develop when the next wet season arrives. In the tropical waters are home to a larger number of marine species, especially in association with coral reefs. The greatest diversity of freshwater species occurs in the great lakes of Africa and in streams of tropical forests (rainforests), especially in the Amazon basin in South
