Of all aquatic animals that live in aquariums, zoos, safaris and so on., Which is certainly better adapted to life in captivity is the dolphin. Animal strong and agile, with great intelligence, dolphins conquered the sympathy of the audience with their fantastic tricks and cute and playful character.

In the wild, dolphins are grouped to form flocks, sometimes over a hundred individuals accompanying the major trends and their jumps are a source of entertainment for passengers and cruise ships.  The dolphin has a characteristic way of swimming, jumping and sinking rhythmically in the water as if they ride the waves. This is because being a mammal, need to surface to breathe, which is increasingly looming head.

The dolphin’s body is spindle-shaped, with a total length of 2 or 2.5 meters. Its head is small and the snout is elongated in a duck-billed. His mouth has 20 to 50 teeth in each jaw. The dorsal fin, tall and slim, is another feature in common with normal fish.

Dolphins are extremely voracious animals. Engulfs all kinds of small fish in large quantities. He lives in warm seas, especially in the Mediterranean and Black Sea.  Its flesh is highly prized, so you will only be pursued in some areas, and usually more than an object to avoid the damage that can be felt while fishing

The gestation (pregnancy) of a dolphin is 12 months and once he is born, the baby dolphin with her mother is 3 to 6 years. During this period they learn fishing techniques and social habits. The dolphins live in relatively small groups and occasionally visit other groups without this being a problem.

Dolphins are very supportive. If a dolphin is dying, other dolphins will come to help his group, supporting all your body to the hole that used to breathe to stay above water level.  The greatest danger to the dolphins are sharks and humans, threatening the dolphin through direct hunting, pollution and because they often get caught in the nets of vessels fishing for other fish such as tuna.

Dolphins use gestures to communicate, but communicate through a noise like a whistle. Some research in the life of dolphins seem to show that the birth of a dolphin, her mother hisses again and again to help your baby recognize your voice and to help the baby to create his own “signature” voice. It is thought that each dolphin has its own “signature” – a staff that is unique whistle, like signing people.

Tuna swim fast, and like other species of fish, cold-blooded. Unlike most species of fish living in the ocean, with white flesh, the flesh of tuna is pink. This is because the tuna’s blood has an oxygen-carrying capacity higher than other fish species.

Some of the larger species such as blue fin tuna can raise their blood temperature above the water temperature with muscular activity. Although this does not mean it is warm blooded, you can live in colder waters and survive in environments that are more extensive than other types of tuna.

The tuna is a very popular fish for feeding. Some varieties such as blue fin, are endangered by abuse of his capture, while others are found in large quantities and yellow fin tuna.

Mercury levels are often relatively high in the tuna and found in a high area of ​​the food chain. It’s hard to keep the tuna in captivity, the aquarium of the bay of Monterrey is one of the few aquariums in the world to successfully maintain the exhibition of tuna.

Against any parameter studied in the different establishments in the world audiological Dr. Sarabia says, backed by scientific studies conducted at the University of Cambridge, Minnesota. The tuna would be valued and distributed towards the free market does not by its size or physical appearance which is considered the color and flaking tuna, but, due to its syntactic calorie it contains.

The object of fishing is opposed to this, since high cost is to analyze the pulse of a fish water stress and thus reveal their data contribution to nutrition and calorie diet. Michael has 6 years researching, after working 12 years in the industrial fisheries rube. \ “The fish itself should not be judged by their appearance, but contents \” was what he repeated several times. It is an aquatic percipient, which must be sold for its real value, not by their size.
