Conservation Status
(IUCN 3.1)
The Blue Whale (Balaenoptera musculus) is the largest of all whales. It comes in four sub-species including:
  • Northern Blue Whale (B. musculus musculus)
  • Southern Blue Whale (B. Musculus intermedia)
  • Indian Ocean Blue Whale (B. musculus indica)
  • Pygmy Blue Whale (B. musculus brevicauda)


Blue Whales can be found in all oceans, mostly depending on the type of sub-species it is. In the winter they are mostly in warmer waters, but in the summer they move to polar waters. In the summer most Blue Whales are feeding in the Antarctic. They all mate in tropic and temperate waters. The Blue Whale is very elusive and hard to find no matter how large their range is, it's numbers are declining.

Conservation StatusEdit

The Blue Whales were safe long ago from early whaling, although in 1868 the invention of the exploding harpoon gun put lots of pressure on the Blue Whales. Whalers started to focus on these types of whales in the 1900s, and Blue Whales were killed by the tens of thousands. The Blue Whale was protected in 1966, almost too late, by the IWC. An estimated low 5,000 Blue Whales are existing today.
