Endangered Species

The paper will begin by a brief introduction to Blue Whales as an endangered species. The discussion will then highlight the environmental significance of the subject and the most important ideas and theories set forth. This section will also incorporate an insight into the data and information that strongly supports the ideas or theories. The subsequent paragraphs will elaborate on the topic of interest and the reason because of which this topic was chosen. The discussion will come to a concluding note by presenting recommendations that can be implemented to make a difference.

In the past 10 years, there was a partial increase of the population in the northern hemisphere due to massive organized around hunting of whales from the 1950s. However, this situation is far from being comparable to all populations of blue whales. Between 1904 and 1967, when they were declared as belonging to a protected species, 350 000 animals were hunted in the southern hemisphere. Thousands more were killed in the 1960s by Soviet whalers. Species endangered since 1996, when a drop of over 50% of the world population was recorded over a period of just 25 years, the whale is unfortunately not yet out of the woods. Although populations are increasing, we talk of whaling. In addition, the largest threat to whales is krill fans the phasing out of food due to the effects of global warming. The current population is estimated at about 2000 individuals.

The food of blue whales is krill (crustacean). Blue whales can eat three tons (3,000 kg) of shellfish per day (between 2 and 4% of body weight). They may also eat small fish (sardines, anchovies and herring), depending on your geographic location and time of year. Blue whales may move at a speed exceeding 30 km / h, but usually move at speeds below 10 km / h. Sometimes younger people make spectacular leaps out of water. For thirty minutes can dive to depths of 150 meters, but usually feed at depths of 100 meters. Blue whales are commonly found as solitary individuals or in pairs. They are grouped in areas established during the mating season (Spilsbury and Spilsbury, p. 71). Females can form groups for breeding. Joint groups were observed in female blue whales and fin whales to perform this function. Much research has been on the songs of whales, but little is known so far for sure. So far it seems clear that the whales use their songs as a means of communication and its ability is yet to be discovered. According to some studies, a large whale songs (For example, the blue whale) could be heard and understood by other individuals at a distance of 4,000 km with the whales would have the oldest and largest communications network on earth.

Clearly this is not a human-like spoken language, but it is clear that this is a language of some sort. Several species of cetaceans have signatures that identify an individual and used to present these other fellows and answer ...
