An enormous blue whale, considered the largest animal on Earth, has washed up onto a beach in southern Chile, probably after dying at sea, local authorities said Sunday.According to the non-governmental Cetacean Conservation Center (CCC) of Chile, the family of Balaenopteridae, or rorquals, includes a variety of species, ranging from the nine-meter (30-foot) minke whale to the blue whale -- which at up to 30 meters is considered the largest animal on Earth. pa/dg/clr/bbk/mlm
