Every year there are dozens of cetaceans and Whales those that run aground on the shores. These phenomena remain a mystery to scientists. The reasons and advanced hypotheses differ depending on the mammals, and the coasts among others, whether it is isolated individuals or entire groups.
Last week, about Scientists gathered for a conference in Perth advanced the rationale for the malnutrition to explain the strong increase in individual strandings of Whales humpbacks off the western shores of Australia. Previously, between 1989 and 2007, the number of cetaceans that ran aground was two to three a year, but in 2008 the number rose to 13 and in 2009 to 46.
Postmortem examinations and analysis of the amount of fat in meat samples taken have shown that most young women species they were in serious condition malnutrition Most had a weak level of fat, essential to provide Energy, thermal regulation and flotation capacity.
The reasons for these lacks could be the intensification of commercial krill fishing, a key element of the regime nutritional of whales and the influence of climate warming on the quantities of these prawns in the seas.
The strandings Individuals can occur when dolphins, whales, porpoises or seals get confused, disoriented, fall ill or are victims of a infection.
It's good
The axis of rotation of the earth has changed. Cetaceans and fish are guided by the sun this phenomenon is also happening in the Mediterranean. If the central axis at the north pole was closer to Canada, you will be in Russia in a few years.
