“Dolphins”

     Dolphins are mammal animals, which live in almost all seas the world. They are found worldwide in temperate and tropical waters, being absent only from 45 degrees of the poles in either hemisphere. In the Pacific Ocean, dolphins are found from northern Japan to Australia and Southern California to Chile. There are also offshore in the tropical Pacific, almost as far as the Hawaiian Islands.

     There are several methods of power, dolphins eat fish and squid and these are the main food. They use very different hunting tactics, for example; often hunt using his speed, but also they look for prey buried in the sand.

     Dolphins have few natural enemies; species of sharks like the bull shark, tiger shark and the great white shark are a potential risk, especially for the young. Environmental pollution of the oceans, seas and rivers is a concern. Pesticides, heavy metals, plastics and other industrial and agricultural pollutants that do not disintegrate rapidly in the environment can cause reduced dolphin populations. On several occasions, especially the tuna purse seine fishery kills dolphins being caught in the nets.

     In these days the International Union for Conservation of Nature is the international body responsible for setting the various states of preservation of species in the world.
