Above “Whales”
Costa Rica is a small country, only 51100 km square located in Central America, which contains a wealth of natural resources in their land as the tropical waters. Recognized worldwide for its attractions, Costa Rica has taken a very important boom in the development of eco-tourism, relaxing and scientist tourism.
Within the natural alternatives that visitors can observe in the Pacific waters of Costa Rica, is the sighting of the humpback whales. Those big cetaceans are easily recognized through numerous signals as the black colouring of its top, bottom white or light gray. The head and lower jaw were covered with small bumps called tubers cephalic or skin characteristics of the species, the tail fin with its black and white patches visible when it plunges, the undulations of his back and his drawings are unique to each edge individual and are used for identification. These whales can weigh up to 40 tons.
Each pectoral fin (also with black spots and white with a drawing itself to each subject) can reach up to one third of the length of the body. That is much more than in any other species of the order Cetacean. To explain this difference so remarkable, several theories have been filed. It could be an evolutionary step to ensure greater manageability. It could also, through greater contact surface, improving the regulation of the internal temperature during migrations between cold and tropical zones.
The humpback whales are among the animals that cover more distance on Earth. Every year, these animals travel between 2,400 to 8,000 kilometers (1,500 to 5,000 miles) abandoning the rich waters of high latitudes, where they feed, to migrate to the warm tropical waters rather than their mating and birthing.
During this journey which may take weeks or months should not eat any food, subsisting on stored fat during times of food in summer. While staying in the area of mating, males emit long and impressive songs and sometimes compete aggressively among themselves by mate with the females.
The pregnant females give birth to their babies in the warm tropical waters and feed with their rich fat milk that helps them grow fast. At the end of winter, all the whales begin the long journey towards polar waters repeating this cycle every year.
In the decades of 1960 and 1970, this impressive animal was endangered because of the commercial hunter, making thinking at the time that this species was about to disappear, but thanks to the entry of an international Veda during these times was reduced considerably by keeping these extermination of a sizeable population that reaches only in the North Pacific more than 10000 individuals
The humpback whales spend 90% of their lives submerged in water, traveling through turbulent seas it impossible for scientists to gather more information on the life and habits of these animals, although there have been discoveries as differentiating males that are emitting the famous singing and females who are caring for the new babies.
One peculiarity of these animals is the song that is recognized as a melody that stands out in the chants from the rest of the animals that inhabit the earth. Studies in this field attribute this song has its own syntax and is very well composed, well-structured like a language, whose purpose is to attract the females.
