Fish

Today i'm going to speak about fish.

Fish are vertebrates, aquatic, typically ectothermic, which have a fusiform body, the members turned into flippers or fins (absent in more basal groups) supported by cartilaginous or bony rays, gills or gills that breathe oxygen dissolved in water (although the use lungfish lungs) and for the most part, the body covered with scales.The breath of fish is quite different from human. They breathe causing water to pass through the mouth and then up to the gills (gills), where oxygen is removed from the water.Fish have a vision of short, though fantastically blind in all directions. They can not hear very well, but have sensitive parts of the body that allow them to realize what is happening nearby. The blood of the fish, unlike ours, is cold.

Dolphins

Today i'm going to speak about dolphins.

The dolphins are animals cetaceans and very good swimmers.His great intelligence is the focus of many studies by scientists. In captivity you can train them to perform variety of tasks, some of great complexity.They can live 25 to 30 years and give birth to a cub at a time. They live in groups, are social animals, both of them, as with other animals and humans.Predators of dolphins are sharks, killer whales and especially humans. The tuna fishermen, tend to look for dolphins, which also hunt, at which there is a mutualism. The dolphin is the school of fish and the fishermen throw their nets trapping the fish and let the dolphins feeding and then pull the nets. Thus, both species benefit from the food. But often the dolphins end up screwing the networks, and may die.
