where does the name killer whale come from
Killer whale According to some authors, the name killer whale is a mistranslation of the 18th century Spanish name asesina-ballenas which means literally whale killer.[16] Basque whalers would have given it such name after observing pods of orcas hunting baleen whales.
Blue whale Long and slender, the blue whale's body can be various shades of bluish-grey dorsally and somewhat lighter underneath.[7] There are at least three distinct subspecies: B. m. musculus of the North Atlantic and North Pacific, B. m. intermedia of the Southern Ocean and B. m. brevicauda (also known as the pygmy blue whale) found in the Indian Ocean and South Pacific Ocean. B. m. indica, found in the Indian Ocean, may be another subspecies. As with other baleen whales, its diet consists almost exclusively of small crustaceans known as krill.[8]
